Background: Ganoderma lucidum triterpenes are bioactive compounds with recognized anti-inflammatory, antitumor, and immunomodulatory properties. This systematic review synthesizes evidence regarding the anti-inflammatory activity of these triterpenes based on studies from the last two decades. Methods: A systematic search was performed in PubMed, Medline, and Embase (2003–2025) for original in vitro and in vivo (non-clinical) studies evaluating G. lucidum triterpene extracts or isolated compounds. Clinical trials, reviews, and multi-species extracts were excluded. The review is registered on PROSPERO (CRD42024510982), and animal study quality was assessed using the SYRCLE Risk of Bias tool. Findings: From over 3000 records, 23 articles were included. Studies utilized diverse models, including macrophages, human PBMCs, and various animal strains (mice, rats, chickens). All studies reported significant anti-inflammatory effects via reduction in pro-inflammatory markers (TNF-α, IL-1β, IL-6), primarily through downregulation of MAPK and TLR-4/NF-κB signaling pathways. Meta-analysis of in vitro data confirmed significant reductions in NO levels (−3.29 [95% CI: −5.21, −1.37]; p = 0.0008), IL-6 (−3.51 [−4.73, −2.29]; p < 0.00001), and TNF-α (−2.20 [−2.93, −1.48]; p < 0.00001). Similar anti-inflammatory profiles were observed in vivo across hepatic and splenic tissues. Interpretation: Evidence consistently demonstrates the potent anti-inflammatory activity of G. lucidum triterpenes, highlighting their potential as therapeutic candidates for inflammatory diseases. However, the structural complexity and isomer diversity of these compounds remain significant barriers to pharmacological standardization. Future research must prioritize clinical translation by investigating compound synergism, bioavailability, and long-term toxicity profiles, which were notably absent in current non-clinical literature.

Ganoderma is a genus of medically significant fungi, that is used in traditional medicine and is increasingly incorporated into modern nutraceuticals and pharmaceuticals. Accurate species identification and product standardization remain major challenges due to morphological plasticity and cryptic diversity. This review articulates current advances in Ganoderma systematics, phylogenetics, and metabolomics, with an emphasis on molecular identification strategies and chemical profiling. Internal transcribed spacer (ITS) sequencing has substantially improved species delineation compared with morphology alone, but its resolving power is limited in closely related species complexes, necessitating complementary multilocus approaches. Advances in metabolomics, and LC-MS- and HPLC-based profiling of triterpenes and polysaccharides, have enhanced species discrimination, chemotaxonomic resolution, and quality control of commercial products. Integrating molecular barcoding with metabolomic fingerprints provides a more robust framework for classification, pharmacological evaluation, and standardization. This review also highlights significant geographic knowledge gaps, particularly in Africa, where molecular and metabolomic data remain scarce despite high species diversity. Full article

Lung cancer is the leading cause of cancer-related deaths worldwide. Non-small cell lung cancer (NSCLC) is the major subtype, accounting for more than 85% of all lung cancer cases. Recent advances in precision oncology have allowed NSCLC patients bearing specific oncogenic epidermal growth factor receptor (EGFR) mutations to respond well to EGFR tyrosine kinase inhibitors (TKIs). Due to the high EGFR mutation frequency (up to more than 50%) observed particularly in Asian NSCLC patients, EGFR-TKIs have produced unprecedented clinical responses. Depending on their binding interactions with EGFRs, EGFR-TKIs are classified as reversible (first-generation: gefitinib and erlotinib) or irreversible inhibitors (second-generation: afatinib and dacomitinib; third-generation: osimertinib). While the discovery of osimertinib represents a breakthrough in the treatment of NSCLC, most patients eventually relapse and develop drug resistance. Novel strategies to overcome osimertinib resistance are urgently needed. In Asian countries, the concomitant use of Western medicine and traditional Chinese medicine (TCM) is very common. Ganoderma lucidum (Lingzhi) and Coriolus versicolor (Yunzhi) are popular TCMs that are widely consumed by cancer patients to enhance anticancer efficacy and alleviate the side effects associated with cancer therapy. The bioactive polysaccharides and triterpenes in these medicinal mushrooms are believed to contribute to their anticancer and immunomodulating effects. This review presents the latest update on the beneficial combination of Lingzhi/Yunzhi and EGFR-TKIs to overcome drug resistance. The effects of Lingzhi/Yunzhi on various oncogenic signaling pathways and anticancer immunity, as well as their potential to overcome EGFR-TKI resistance, are highlighted. The potential risk of herb–drug interactions could become critical when cancer patients take Lingzhi/Yunzhi as adjuvants during cancer therapy. The involvement of drug transporters and cytochrome P450 enzymes in these herb–drug interactions is summarized. Finally, we also discuss the opportunities and future prospects regarding the combined use of Lingzhi/Yunzhi and EGFR-TKIs in cancer patients. Full article

Background/Objective: Ganoderma spp. have long been studied for their bioactive pharmacological properties, and their biomass and extracts have been obtained from various sources. This study adopts a novel approach: enriching a liquid culture of Ganoderma mexicanum with a vineyard pruning waste extract to identify bioactive compounds with antiproliferative activity through enriched chromatographic fractions. Methods: The ethanolic extract from a mycelial culture was separated following a partitioning process, and the hexane fraction was subsequently separated in a chromatographic column. The fractions were evaluated for their antiproliferative properties against cancer cell lines. The interactions of the molecules identified with peroxisome proliferator-activated receptor gamma (PPAR-γ) were analyzed via molecular docking. Results: Three chromatographic fractions (FH11–FH13) exhibited antiproliferative activity which was significantly more effective against non-small lung cancer cells (A549). The cells treated with the crude extract and fractions presented a balloon-like morphology. A chemical analysis of the active fractions allowed us to identify four compounds: one fatty acid (9-Hydroxy-10E,12Z-octadecadienoic acid) and three triterpenes (ganoderic acids DM, TQ, and X). These compounds showed interactions with the PPAR-γ receptor through molecular docking. Conclusions: Ganoderma mexicanum is a promising source of compounds with antiproliferative activity that could serve as natural ligands for PPAR-γ and has possible applications in lung cancer therapy.

Ganoderma lucidum is a traditional Chinese medicinal fungus, and ganoderma triterpenoids (GTs) are one of the main bioactive compounds. These compounds have various pharmacological functions, including anti-tumor, antioxidant, anti-inflammatory, liver-protective, and immune-regulating effects. However, the manner in which they accumulate, and their biosynthesis mechanisms remain unclear. To screen for the genes that are involved in the biosynthetic pathway of GTs, this study analyzed the differential metabolites and differentially expressed genes (DEGs) among different growth stages of G. lucidum, including the primordia (P), the matured fruiting body (FM), and the post-spore fruiting bodies (FP) using targeted metabolomics and transcriptomics analysis, respectively. The results showed that a total of 699 components were detected, including lignans, terpenoids, amino acids and derivatives, and phenolic acids, among others. Among them, a total of 112 types of triterpenes were detected. Compared with the primordia, there were eight differential metabolites of triterpenoids, with three decreasing and five increasing in the FM stage. A comparison between the FM stage and the FP stage revealed that there were 13 differential metabolites of triterpenoids. A transcriptomics analysis showed that there were 371 DEGs in the P_vs_FM group, including 171 down-regulated genes and 200 up-regulated genes. In the FM_vs_FP group, 2567 DEGs were identified, with 1278 down-regulated genes and 1289 up-regulated genes. Through targeted metabolomics and transcriptome correlation analysis, six TFs and two CYP450s were significantly associated with four triterpenoid components. The results showed that these TFs and CYP450s were positively or negatively correlated with the four triterpenoid components. In addition, interestingly, some flavonoids and phenolic compounds, which have been reported in plants, were also detected in G. lucidum, indicating that it has the potential to be engineered into a strain capable of synthesizing flavonoid compounds. This study provides useful information about key genes involved in GT biosynthesis, but further exploration and in-depth research are needed to better understand the functions of these genes.

Dietary intervention is the basis for the treatment of diabetes mellitus. This study employed Ganoderma lucidum (GL) mycelium to ferment a compound medium of oat and purple potato (OPP), optimized fermentation conditions to increase the triterpene content in the resulting product (F-OPPF), and systematically investigated the impact of fermentation on the nutritional quality, structural characteristics, and functional properties of OPP. The results indicated that the triterpene content in F-OPPF significantly increased from 8.53 mg/g to 17.23 mg/g under optimal conditions (temperature: 28 °C, inoculum size: 10%, material quantity: 36 g/250 mL, and fermentation time: day 13). Fermentation resulted in enhanced nutritional quality, with increased contents of protein, soluble protein, crude fiber, ash, mineral elements, essential amino acids, polysaccharides, flavonoids, and total phenols. Mycelium not only enveloped the OPP surface but also penetrated its interior, forming a porous honeycomb-like structure. The types of reactive groups and crystals (C + V-type) were not changed after fermentation, while the crystallinity increased. F-OPPF exhibited positive changes in thermogravimetric properties, antioxidant and hypoglycemic activities, and adsorption capacity of insoluble dietary fiber. Additionally, incorporating F-OPPF into the diet markedly reduced fasting blood glucose levels and promoted weight gain in T2DM rats induced by a high-fat diet and streptozotocin. The fermented groups exhibited improvements in glyco- and lipo-metabolism, oxidative stress, and the function and pathological morphology of the pancreas, liver, and kidneys compared to the unfermented group. Collectively, these findings suggested that GL mycelium fermentation enhanced the nutritional and functional values of OPP, and F-OPPF holds potential as a raw material for developing diabetic-friendly foods.

Ganoderma lingzhi, a species of white rot fungus, possesses the highest abundance of lignocellulose-degrading enzymes among these fungi, as well as a relatively high carbon conversion rate. Corn straw, as an important sustainable resource, is used as a substrate for the liquid culture of G. lingzhi. However, little is known about the genes encoding the lignocellulose degradation and polysaccharide and triterpenoid biosynthetic pathways involved in this process. This paper employs transcriptomics to uncover the key genes involved in lignocellulose degradation and the synthesis of polysaccharides and triterpenoids during the liquid fermentation of G. lingzhi using corn straw as the substrate, as well as their associations. Carbohydrate-Active enzymes analysis of differential genes in the sequencing results was used to analyze the genes related to lignocellulose degradation. Among these, 43 core genes encoding CAZymes were obtained after 0 to 5 days of fermentation, and 25 core genes encoding CAZymes were obtained after 5 to 12 days of fermentation. The differential expression levels of DN3690_c0_g1 (EGL), DN3627_c0_g2 (XYN), DN4778_c0_g1 (XYN), DN2037_c0_g1 (LACC), and DN277_c2_g1 (MnP) were used to identify the key genes. The polysaccharide synthesis metabolic pathway favored mannitol synthesis, and the expression of triterpene precursor-metabolizing enzyme genes revealed higher expression levels of key enzyme genes such as ACAT, HMGS, and MPK. A correlation clustering analysis of genes related to lignocellulose degradation, polysaccharide, and triterpene anabolism during liquid fermentation showed that lignocellulose degradation genes mainly influenced arabinose and mannitol anabolism, as well as the synthesis of triterpene precursors.

Edible fungi have certain photo-sensitivity during the mushroom emergence stage, but there have been few relevant studies on the responses of Ganoderma lucidum to different light irradiation conditions. Ganoderma lucidum were planted in an environmentally controllable mushroom room with different light supply modes that were, respectively, continuous white light (CK), red light (R), green light (G), blue light (B), and intermittent red light (R-), green light (G-), and blue light (B-), with a total light intensity of 15 μmol·m⁻²·s⁻¹ and a light/dark (L/D) period of 12 h/12 h for each treatment. The interval in intermittent light treatments was 30 min. The optimal light supply mode suitable for the growth of Ganoderma lucidum was explored by analyzing the characteristics, nutritional quality, and extracellular enzyme activity in mushrooms exposed to different light treatments. The results showed that red light (whether in continuous or intermittent supply modes) inhibited the fruiting body differentiation of Ganoderma lucidum, showing delayed differentiation or complete undifferentiation. The highest stipe length and pileus diameter of fruiting bodies were detected under G- treatment, which were, respectively, increased by 71.3% and 3.2% relative to the control. The highest weight of fruiting bodies was detected under G treatment, which was significantly increased by 21.4% compared to the control (p < 0.05). Intermittent light mode seemed to be more conducive to the size development of the fruiting body, while continuous light mode was beneficial for increasing the weight. The highest contents of crude protein and total triterpenes in pileus were detected under G treatment (significantly 14.9% and 28.1% higher than the control, respectively), while that of the crude polysaccharide was detected under G- treatment (significantly 35.7% higher than the control) (p < 0.05). The highest activities of extracellular enzymes such as cellulase, hemicellulase, laccase, lignin peroxidase, and amylase were detected in fruiting bodies subjected to G treatment, which were significantly increased by 11.9%~30.7% in the pileus and 9.5%~44.5% in the stipe. Green light might increase the weight and nutrient accumulation in the pileus of Ganoderma lucidum via up-regulating the extracellular enzyme activities. This study provides an effective light supply strategy for regulating the light environment in the industrial production of Ganoderma lucidum. Full article

Ganoderma triterpenes and spore powder have shown promising results in mitigating cadmium-induced renal and hepatic injuries. Ganoderma lucidum active peptide GLP4 is a natural protein with dual antioxidant activities derived from the mycelium of Ganoderma lucidum. However, its efficacy in alleviating cadmium-induced lung injury remains unexplored. This study aims to investigate the protective effects of GLP4 against cadmium-induced lung injury in mice. Mice were exposed to cadmium chloride via nebulization to induce lung injury. The protective effect of GLP4 was assessed by measuring the total cell count in BALF, levels of inflammatory cytokines, and the expression of NLRP3 in lung tissues a through histopathological examination of lung tissue changes. The results showed that GLP4 significantly mitigated histopathological damage in lung tissues, decreased the secretion of inflammatory cytokines, and reduced the expression of NLRP3, which was elevated in cadmium-exposed mice. In vitro studies further revealed that GLP4 inhibited the cadmium-induced activation of the NLRP3 inflammasome. Notably, acute cadmium exposure by the respiratory tract did not affect the liver and kidneys of the mice. The findings suggest that GLP4 reduces cadmium-induced lung injury in mice by inhibiting the activation of the NLRP3 inflammasome, which provides a theoretical foundation for using Ganoderma lucidum as a preventive and therapeutic agent against cadmium poisoning.

Ganoderma lingzhi is an important medicinal fungus, and it is particularly important to select strains with high yields and active substance contents. In this study, protoplasts of G. lingzhi were thermally inactivated to destroy intracellular enzyme proteins and preserve DNA. The DNA of G. resinaceum was damaged by ultraviolet (UV) radiation, and other components of the protoplasm except DNA were preserved. Then, the protoplast was induced using polyethylene glycol (PEG) for fusion. The results showed that the optimal thermal inactivation conditions for G. lingzhi were 30 min in a 45 °C water bath, and the optimal UV inactivation conditions for G. resinaceum were 70 s of irradiation using a 20 W UV lamp at a vertical distance of 15 cm. Antagonistic tests, internal transcribed space (ITS) and mitochondrial DNA identification, intersimple sequence repeat (ISSR) molecular markers and morphology were used to distinguish the parents from the fusants. Four true fusants were obtained, and the yield was 2.5%. The fruiting body yield of the fusants was significantly higher than that of G. lingzhi, and the polysaccharide and triterpene contents of the RAD-64 fusant were significantly higher than those of G. lingzhi. The results presented in this paper show that protoplast fusion technology can effectively improve G. lingzhi varieties and support the breeding of new varieties. Full article

The genus Ganoderma has been little studied in arid areas worldwide. Ganoderma subincrustatum and Ganoderma weberianum strains were obtained from the Sonoran Desert, Sonora, Mexico. Ganoderma spp. synthesize triterpenoids such as ganoderic acids with antiproliferative activity because they inhibit specific targets, induce apoptosis, and increase the activity of killer cells. Mycelium and fruiting body chloroform extracts from G. subincrustatum and G. weberianum were tested on HeLa, A549, L-929, and RAW 264.7 cell lines. Extracts from the fruiting body present higher antiproliferative activity than mycelium. All extracts induced vesicle and cellular debris formation in all cell lines, being non-selective for cancerous cells. Chloroform extract from G. subincrustatum fruiting bodies presented higher activity against all cell lines. Fractions F7 and F15 from this extract exhibited an IC₅₀ of 37.9 and 41.9 µg/mL on the A549 cell line, respectively; however, chloroform crude extract showed higher activity (IC₅₀ of <25 µg/mL) in all cell lines. Flow cytometry assays of F7 revealed cell death by apoptosis in A549 cells. NMR suggested the presence of ganoderic acids in F7. In future research, it will be interesting to characterize these fractions (metabolites, their bioactivities, and mechanism of action). Full article

(1) Background: Ganoderic acids (GAs) are specific triterpenes of Ganoderma lucidum. The HPLC fingerprint profile of GAs of the fruiting body is well known, but their mycelial fingerprinting remains unclear. (2) Methods: An ethanol extract of the mycelium of G. lucidum (YK-01) was further purified via preparative HPLC. The triterpenoid compositions for four strains of G. lucidum and one strain of G. formosanum (purple lingzhi) were analyzed using HPLC. (3) Results: Nineteen lanostane triterpenes, including five new triterpenes, GA-TP (1), ganodermic acid J_c (GmA-J_c) (2), GmA-J_d (3), GA-TQ₁ (4), and ganoderal B₁ (5), and fourteen known triterpenes 6–19 were isolated from the ethanol extract. Their structures were identified by mass and extensive NMR spectroscopy. A green chemical HPLC analytical method was developed using ethanol and acetic acid as a mobile phase, and all isolated compounds can be well separated. These triterpenes comprise a unique HPLC chromatograph of the G. lucidum mycelium. All four G. lucidum strains showed the same HPLC chromatographic pattern, whereas G. formosanum displayed a different pattern. Quantitation methods for ganoderic acid T (10) and S (12) were also validated. (4) Conclusions: The triterpenoid HPLC analytical method can be used to identify the G. lucidum species and to determine the contents of GA-T and GA-S. Full article

Medicinal mushrooms, e.g., Lion’s Mane (Hericium erinaceus (Bull.) Pers.), Reishi (Ganoderma lucidum (Curtis) P. Karst.), Chaga (Inonotus obliquus (Ach. ex Pers.) Pilát), Cordyceps (Ophiocordyceps sinensis (Berk.) G.H. Sung, J.M. Sung, Hywel-Jones and Spatafora), Shiitake (Lentinula edodes (Berk.) Pegler), and Turkey Tail (Trametes versicolor (L.) Lloyd), are considered new-generation foods and are of growing interest to consumers. They are characterised by a high content of biologically active compounds, including (1,3)(1,6)-β-d-glucans, which are classified as dietary fibre, triterpenes, phenolic compounds, and sterols. Thanks to their low-fat content, they are a low-calorie product and are classified as a functional food. They have a beneficial effect on the organism through the improvement of its overall health and nutritional level. The biologically active constituents contained in medicinal mushrooms exhibit anticancer, antioxidant, antidiabetic, and immunomodulatory effects. In addition, these mushrooms accelerate metabolism, help fight obesity, and slow down the ageing processes thanks to their high antioxidant activity. The vast therapeutic properties of mushrooms are still not fully understood. Detailed mechanisms of the effects of medicinal mushrooms on the human organism still require long-term clinical studies to confirm their nutraceutical effects, their safety of use, and their dosage. Medicinal mushrooms have great potential to be used in the design of innovative functional foods. There is a need for further research on the possibility of incorporating mushrooms into food products to assess the interactions of their bioactive substances with ingredients in the food matrix. This review focuses on the properties of selected medicinal mushrooms and their effects on the human organism and presents current knowledge on the possibilities of their use in the production of functional foods.
