Special Issue Information

Dear Colleagues,

Medicinal plants are a rich source of structurally diverse natural products. These compounds display a wide array of biological activities (e.g., antioxidant, anti-inflammatory, antimicrobial, enzyme inhibition, neuroprotection). Despite this promise, challenges remain in efficiently extracting, identifying and applying such molecules.

This Special Issue focuses on recent advances and innovative approaches in the extraction, isolation, characterization, and utilization of bioactive compounds from medicinal plants. We invite original research and review articles on medicinal plants that explore novel extraction methods, chemical profiling, and evaluation of functional properties using in vitro and in vivo studies, as well as the application of plant extracts in variety of products. In particular, we welcome submissions specially focusing on the application of medicinal plant extracts and products in the formulation of pharmaceuticals, nutraceuticals, cosmetics, or functional food products.

Key topics include, but are not limited to:

  • Cutting-edge extraction and purification techniques for the preparation of extracts from medicinal plants
  • Identification and structural characterization of natural bioactive compounds
  • Innovative formulations for functional food products, pharmaceuticals, nutraceuticals, and cosmetics
  • Sustainable and environmentally friendly extraction approaches
  • Bridging ethnopharmacological or traditional-use evidence with modern phytochemical, molecular biology and biotechnology approaches.
  • Valorisation of by-products or under-utilised medicinal plant species.

This Special Issue aims to provide a platform for advancing scientific understandings of plant-derived bioactives and their innovative applications across multiple industries.

Medlar (Mespilus germanica L.) fruit presents a good source of bioactive compounds. This study aimed to optimize the traditional extraction method, maceration, in order to obtain extracts rich in polyphenols. The total phenolic compounds (TPC) from physiologically ripe (PRMFs) and consumable ripe (CRMFs) medlar fruits were extracted to develop models with high accuracy and prediction capacity by response surface methodology (RSM). Furthermore, the main phenolic compounds in the extracts were quantified using HPLC, and the extracts were tested for antioxidant activity and hypoglycemic activity. The extracts were prepared according to a central composite design. The extraction parameters for both PRMFs and CRMFs were time (30–210 min), ethanol concentration (20–80%) and solid-to-solvent ratio (1:10–1:50). The obtained results indicated that the optimal conditions for the extraction were 210 min, 66.55% ethanol, and 1:50 solid-to-solvent ratio (PRMF), and 120 min, 74.96% ethanol, and 1:50 solid-to-solvent ratio (CRMF). Under the optimized conditions, values for TPC were in agreement with the values predicted by RSM. Isoquercitrin, rutin, procyanidin B2, chlorogenic acid and caffeic acid were the most abundant compounds in both PRMF and CRMF optimized extracts. TPC, antioxidant activity, and inhibition of α-glucosidase and α-amylase enzymes did not show significant differences (p > 0.05) among PRMF and CRMF extracts. Full article

This study evaluated activities of crude extracts from different parts of the tree of heaven (Ailanthus altissima (Mill.) Swingle) collected in Slovenia and Hungary, using effect-directed analyses based on hyphenation of high-performance thin-layer chromatography (HPTLC) and nine in vitro assays performed in situ on chromatographic plates after the separation. HPTLC separation combined with a set of four antibacterial assays, two antifungal assays, and three enzyme inhibitor assays to evaluate the extracts of 15 plant parts: young shoots, young leaves, mature leaves, yellow leaves, petioles of leaves, petioles of male inflorescences, petioles of fruits, female inflorescences, young fruits, male inflorescences, mature male inflorescences, bark of 1–2-year branches, bark of 2-year branches, bark of tree trunk, and bark of roots. Antibacterial activities against Gram-positive bacteria (Bacillus subtilis, Rhodococcus fascians) and Gram-negative bacteria (Aliivibrio fischeri, Pseudomonas syringae pv. maculicola (Psm)), as well as inhibition of enzymes α-glucosidase, lipase, and acetylcholinesterase, were observed for all extracts. Extracts differed in their antifungal activities. Extracts of young shoots, mature leaves, petioles of leaves, and bark of roots showed antifungal activity against plant pathogens Fusarium avenaceum and Bipolaris sorokiniana. Extracts of yellow leaves, male inflorescences, bark of 1–2-year branches, and bark of tree trunks were only active against F. avenaceum, whereas extracts of young leaves were only active against B. sorokiniana. This study is the first to report that A. altissima extracts exhibit (1) antifungal activity against F. avenaceum and B. sorokiniana; (2) antibacterial activity against A. fischeri, Psm, R. fascians, and B. subtilis (except leaves, bark of branches and bark of tree trunks); and (3) inhibitory activity toward lipase, α-glucosidase (except bark of tree trunks), and acetylcholinesterase (except bark of tree trunks).
