The study aimed to evaluate antioxidant, anticholinesterase and antidiabetic properties of (A. St.-Hil.) Baill. The inflorescence methanol extract and the ethyl acetate fraction of leaves and stems reported the highest Relative Antioxidant Capacity Index (RACI), whereas the dichloromethane fraction of leaves was the best inhibitor of -amylase and -glucosidase. T-3--methyl-resveratrol-2---glucoside, lithospermoside, 2,5-dimethoxy--benzoquinone, lup-20(30)-ene-3β,28-diol, 7--methylgenistein, apigenin and luteolin and amentoflavone were isolated from . Resveratrol derivative was isolated for the first time in Ochnaceae family. Luteolin, followed by apigenin, reported the highest Relative Antioxidant Capacity Index and they were also the best inhibitors of α-glucosidase enzyme.
该研究旨在评估（A. St.-Hil.）Baill.的抗氧化、抗胆碱酯酶和抗糖尿病特性。花序甲醇提取物以及叶和茎的乙酸乙酯部分的相对抗氧化能力指数（RACI）最高，而叶的二氯甲烷部分是α-淀粉酶和α-葡萄糖苷酶的最佳抑制剂。从该植物中分离出了T-3'-甲基白藜芦醇-2''-葡萄糖苷、紫草酸苷、2,5-二甲氧基-对-苯醌、羽扇-20(30)-烯-3β,28-二醇、7-甲氧基染料木黄酮、芹菜素、木犀草素和穗花杉双黄酮。白藜芦醇衍生物首次在金莲木科中被分离出来。木犀草素的相对抗氧化能力指数最高，其次是芹菜素，它们也是α-葡萄糖苷酶的最佳抑制剂。
