St. John’s wort (Hypericum perforatum L.) has been extensively utilized across various traditional medicinal systems, including ancient Greek medicine, traditional Chinese medicine, and Islamic medicine. H. perforatum is a well-known medicinal plant due to the presence of hypericin and hyperforin, which are natural antidepressants. Recent studies indicate that the inflorescences of wild H. perforatum are a source of rare tocotrienols, primarily δ-T3. Similar studies are lacking for cultivated species. H. perforatum was grown for three years. At full bloom each year, the plant was cut and separated into its parts: stems, leaves, flower buds, and flowers. Tocotrienols (T3s) were present in each part of the H. perforatum. The lowest concentration of tocotrienols was recorded in stems and the highest in flower buds (1.7–4.2 and 88.2–104.7 mg/100 g dry weight, respectively). Flower buds and flowers were the main source of α-T3 and δ-T3 tocotrienols. The plant part has a significant impact on the tocochromanol profile and concentration, while the year of harvest/plant aging does not. The present study demonstrates that cultivated H. perforatum flower heads are the first known flowers with relatively high concentrations of tocotrienols. St. John’s wort flower buds accumulate tocotrienols over tocopherols, regardless of the year of the plant. Full article

Natural extracts derived from plants have gained attention as potential therapeutic agents for obesity management. Some natural extracts were demonstrated to inhibit pancreatic lipase and alpha amylase, potentially influencing nutrient absorption and contributing to weight management. Pinus nigra subsp. laricio (Poir.) Maire, commonly known as the Calabrian pine or larch pine, is a subspecies of the black pine native to the mountains of southern Italy and Corsica. This study investigated the phytochemical content and antioxidant (DPPH and β-carotene bleaching assays) and enzymatic (lipase and amylase inhibition) activities of ethanolic extracts from apical shoots and branches, fractionated into n-hexane, dichloromethane, and ethyl acetate. All the extracts were also subjected to a preliminary evaluation of their anti-inflammatory potential by measuring the ability to inhibit nitric oxide (NO) production in RAW 264.7 macrophages. The ethyl acetate branch fraction exhibited the strongest antioxidant activity (DPPH IC50 15.67 ± 0.16 μg/mL), while the total branch extract best inhibited pancreatic lipase (IC50 0.62 mg/mL). Amylase inhibition was strongest in the ethyl acetate apical shoot fraction (IC50 22.05 ± 0.29 µg/mL). The branches’ hexane and dichloromethane fractions showed the greatest anti-inflammatory potential, inhibiting NO production in RAW 264.7 cells with IC50 values comparable to the positive control.

Lilium lancifolium Thunb. is a herbal medicine that is widely used to treat inflammation and lung diseases. In this study, a simultaneous quantitative method was developed for the quality control of BLL using high-performance liquid chromatography coupled with a photodiode array detector (HPLC–PDA), and their antioxidant effects were evaluated. Eight regalosides (i.e., regaloside A, B, C, E, F, H, I, and K) were selected as marker substances and separated on a Gemini C18 reversed-phase analytical column by gradient elution with distilled water–acetonitrile mobile phase containing 0.1% (v/v) formic acid. The method was validated with respect to linearity, sensitivities (limit of detection (LOD) and limit of quantitation (LOQ)), accuracy, and precision. The antioxidant effects of the extract and each component were evaluated using the 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay and 2-2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) assay. The coefficients of determination values used as indicators of linearity for all components were ≥0.9999. LOD and LOQ concentrations were 0.10–0.66 μg/mL and 0.29–2.01 μg/mL, respectively. The recovery was 95.39–103.925% (relative standard deviation; RSD ≤ 2.55%), and precision RSD was <2.78%. The HPLC–PDA method was applied to real samples, and all components were detected at 1.12–29.76 mg/freeze-dried g. The evaluation of antioxidant effects showed that regalosides C, E, and K exhibited significant antioxidant effects. Our knowledge will be appropriately utilized in raw material management and conducting clinical and non-clinical studies on L. lancifolium or herbal medicine prescriptions containing L. lancifolium.

The use of medicinal herbs is highly developed in Haiti. However, there is a significant lack of knowledge in the literature on medicinal plants and their uses. The objective of this study was to determine the knowledge and practices of Haitian families for the prevention/treatment of COVID-19, influenza, and respiratory diseases, as well as the mode of preparation and administration of the plants. Individuals were interviewed using the TRAMIL questionnaire as the information holder. The data obtained were analyzed by calculating 5 indices (relative frequency of citation, use value, the family use value, informant consensus factor, and fidelity level). The study surveyed 120 Haitians and collected 75 plants from 43 botanical families. The botanical family most used for all these preventions and remedies is the Lamiaceae. The highest ranked species with a relative frequency of citation value > 0.3. Infusion, decoction, and in the form of punch are the methods used for the remedies. The study found that the use of herbal remedies is still prevalent in the study area, and many of the commonly used plants have been scientifically validated. However, some plants, such as Samyda rosea Sims, lack sufficient research and are recommended for further investigation. Full article

Plants have long been used to treat serious illnesses in both humans and animals. A significant underappreciated medicinal tree, Peltophorum africanum Sond is utilized by many different ethnic groups to cure a wide range of illnesses. A variety of electronic databases, including ScienceDirect, Scopus, Scielo, Scifinder, PubMed, Web of Science, Medline, and Google Scholar, were used to search the literature on P. africanum, using key words such as uses, survey, pharmacology, antigonococcal, toxicity, phytochemistry and others. Further data was obtained from several scholarly theses, dissertations, and books on general plant sciences, ethnomedicine, and other pertinent ethnobotanical topics. The plant species possess very important pharmacological activities in vitro, which includes antimicrobial, anti-HIV, antioxidant, anticancer, antidiabetic, and other activities. Phytochemically, the plant possesses various classes of compounds, dominated by flavonols, which may well explain its wider range of pharmacological activities. Although the plant is promising anti-HIV activity, the mode of action and safety profiles of the plant also need to be explored as its extracts exerted some degree of mutagenicity. It is also important to further explore its ethnoveterinary use against a plethora of nematodes that infects both wild and domestic animals. Given its potent pharmacological activity, the further in vivo studies need to be explored to ascertain the comprehensive toxicology of the plant species, thereby developing possible medications. The plant species may further be elevated to a potent pharmaceutical product against plethora of infections. Full article
