中文摘要: 研究鹰嘴豆水提物的不同组分对 a-糖苷酶的抑制作用,其对 a-糖苷酶的半抑制浓度为 0.20 mg/mL。将鹰嘴 豆水提物经过大孔树脂 D101 筛选,对其不同组分进行活性评价。结果发现鹰嘴豆水提物经过不同乙醇浓度洗脱,其 对 α-糖苷酶的抑制效果逐渐增强,其中 40 %乙醇组分对 α-糖苷酶的抑制效果最强。同时应用 LC-MS 定性分析组 分,发现鹰嘴豆水提物中可能存在鹰嘴豆芽素 A、大豆皂苷 Bb、芒柄花素等物质。说明这些皂苷及异黄酮类化合物影 响 α-葡萄糖苷酶抑制效果。
Abstract:This paper reports the α -glucosidase inhibition of the aqueous extract from different chickpea components is determined. It is found that its half-inhibitory concentration (IC50) to the enzymic activity of α - glycosidase is 0.20 mg/mL. The chickpea aqueous extracts are screened by macroporous resin D101 for evaluation of activity of the different components in it. The results show that through the elution by ethanol of different concentrations, chickpeas aqueous extract shows stronger inhibition effect on α-glycosidase gradually, components with the 40 % ethanol exhibits the strongest inhibitory effect. At the same time, it is determined by LC-MS chromatograms that the different components in the chickpeas aqueous extract may consist of the Biochanin A、Soyasaponin Bb、Formononetin etc, which illustrate that these saponin and isoflavone compounds influence the inhibition effect from α-glycosidase.
