Abstract

Few studies have been conducted on phytochemical constituents and biological activities of Centaurea pumilio L. Hence, fractions of root ethanolic extract were subjected to chromatographic separation. Eight compounds were isolated for the first time from the roots – one is new, hop-17(21)-ene-3β-ylformate (1) and seven are known. Fifty-three compounds were tentatively identified in the fractions of the root and aerial parts using UPLC-ESI-MS/MS analysis. Moreover, the ethyl acetate fraction of the roots exhibited an in vitro hypoglycemic effect in that it inhibited the α-amylase enzyme compared to acarbose. Additionally, total ethanolic extracts as well as different soluble fractions of the root and aerial parts were examined for their cytotoxic activity.

新藿香类化合物、UPLC-ESI-MS/MS 化学成分分析以及积雪草的生物活性
因此,对根部乙醇提取物的馏分进行了色谱分离。首次从根部分离出 8 种化合物,其中 1 种是新化合物,即 hop-17(21)-ene-3β-ylformate (1),7 种是已知化合物。通过 UPLC-ESI-MS/MS 分析,在根部和气生部分的馏分中初步鉴定出 53 种化合物。此外,与阿卡波糖相比,根的乙酸乙酯馏分具有体外降血糖作用,能抑制α-淀粉酶。此外,还研究了根部和气生部分的乙醇提取物以及不同的可溶性馏分的细胞毒性活性。
