In current study antioxidant, antidiabetic, antimicrobial, anticholinesterase, and human carbonic anhydrase I, and II (hCA I and II) isoenzymes inhibition activities of Astrodaucus orientalis different parts were investigated. Achetylcholinesterse (AChE) and butyrylcholinesterse (BChE) inhibitory activities of octyl acetate were determined via molecular docking. Quantitative assessment of specific secondary metabolites was conducted using LC-MS/MS. An examination of chemical composition of essential oils was carried out by GC-MS/MS. A thorough exploration of plant's anatomical characteristics was undertaken. The highest phenolics level and DPPH antioxidant capacity were seen in root and fruit. Fruit essential oil demonstrated the highest AChE inhibition (44.13±3.61 %), while root dichloromethane sub-extract had the best inhibition towards BChE (86.13±2.58 %). Cytosolic hCA I, and II isoenzymes were influentially inhibited by root oil with 1.974 and 2.207 μM IC 50 values, respectively. The most effective extracts were found to be root all extract/sub-extracts (except water) against C. tropicalis and C. krusei strains with MIC value 160>μg/mL. Sabinene (29.4 %), α-pinene (20.2 %); octyl acetate (54.3 %); myrcene (28.0 %); octyl octanoate (71.3 %) were found principal components of aerial parts, roots, flowers, and fruits, respectively. Flower essential oil, fruit dicloromethane and ethyl acetate exhibited potent α-glucosidase inhibitory activity with 900, 40, and 937 μg/mL IC 50 values, respectively., (© 2023 Wiley-VHCA AG, Zurich, Switzerland.)

Gagea genus, which is native to the Mediterranean and Black Sea regions, has attracted significant attention due to its biodiversity and potential health benefits. In this study, the biochemical composition and biological activities of methanol extracts from various parts of G. taurica were investigated, along with their anatomical and morphological characteristics. The best antimicrobial activity was found to be MeOH extracts of corm and leaf against several Candida strains with MIC=640 μg/mL. The highest level of phenolics together with significant results of antioxidant activities were observed in flowers extracts. The α-amylase inhibition assay results showed that the highest inhibition percentage was observed with acarbose (59 %), followed by leaf extract (43 %). Leaf exhibited the most effective inhibitory activity in AChE inhibition assay, whereas flower demonstrated the most significant inhibitory activity in BChE inhibition assay. Hesperidin was found as 1621.0001 ng/ml value in flower extract and 283.9339 ng/ml value leaf., (© 2023 Wiley-VHCA AG, Zurich, Switzerland.)
