Abstract:
Six extracts (water, ethanol, ethanol‐water, ethyl acetate, dichloromethane, and n ‐hexane) of Astragalus caraganae were studied for their biological activities and bioactive contents. Based on high‐performance liquid chromatography‐mass spectrometry (HPLC‐MS), the ethanol‐water extract yielded the highest total bioactive content (4242.90 µg g −1 ), followed by the ethanol and water extracts (3721.24 and 3661.37 µg g −1 , respectively), while the least total bioactive content was yielded by the hexane extract, followed by the dichloromethane and ethyl acetate extracts (47.44, 274.68, and 688.89 µg g −1 , respectively). Rutin, p ‐coumaric, chlorogenic, isoquercitrin, and delphindin‐3,5‐diglucoside were among the major components. Unlike the dichloromethane extracts, all the other extracts showed radical scavenging ability in the 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical scavenging assay (8.73–52.11 mg Trolox equivalent [TE]/g), while all extracts displayed scavenging property in the 2,2‐azino‐bis(3‐ethylbenzthiazoline‐6‐sulfonic acid) (ABTS) radical scavenging assay (16.18–282.74 mg TE/g). The extracts showed antiacetylcholinesterase (1.27–2.73 mg galantamine equivalent [GALAE] /g), antibutyrylcholinesterase (0.20–5.57 mg GALAE/g) and antityrosinase (9.37–63.56 mg kojic acid equivalent [KAE]/g) effects. The molecular mechanism of the H 2 O 2 ‐induced oxidative stress pathway was aimed to be elucidated by applying ethanol, ethanol/water and water extracts at 200 µg/mL concentration to human dermal cells (HDFs). A. caraganae in HDF cells had neither a cytotoxic nor genotoxic effect but could have a cytostatic effect in increasing concentrations. The findings have allowed a better insight into the pharmacological potential of the plant, with respect to their chemical entities and bioactive contents, as well as extraction solvents and their polarity.
