摘要
目的筛选三黄泻心汤抑制α-淀粉酶和α-葡萄糖苷酶抑制活性的有效部位,并研究其活性成分。方法三黄泻心汤水煎液采用大孔树脂分段洗脱得到水部位、30%乙醇部位、60%乙醇部位、95%乙醇部位,对水煎液及4个洗脱部位进行α-淀粉酶和α-葡萄糖苷酶体外活性抑制试验,筛选最佳活性部位,再通过高效液相色谱分析其活性成分,并进行方法学考察与含量测定。结果筛选得到抑制α-淀粉酶活性最佳部位为30%乙醇部位,IC50为1.707mg·mL^(-1),活性成分主要有黄芩苷,小檗碱,汉黄芩苷,黄芩素,芦荟大黄素,大黄酸,大黄素,其中黄芩苷含量最高(177.588 mg·g^(-1)),汉黄芩苷次之(30.546 mg·g^(-1));抑制α-葡萄糖苷酶活性最佳部位为60%乙醇部位,IC50为0.0123mg·mL^(-1),活性成分有黄芩苷,小檗碱,汉黄芩苷,黄芩素,芦荟大黄素,大黄酸,大黄素,大黄酚,大黄素甲醚,其中黄芩苷含量最高(181.631mg·g^(-1)),小檗碱次之(71.724 mg·g^(-1))。结论三黄泻心汤在一定程度上对α-淀粉酶及α-葡萄糖苷酶均有活性抑制作用,对α-葡萄糖苷酶的抑制作用优于α-淀粉酶,对开发α-葡萄糖苷酶抑制剂具有一定参考价值。
Objective To screen the effective parts of Sanhuang Xiexin Decoction for inhibiting the inhibitory activities ofα-amylase andα-glucosidase,and to study its active components.Methods The aqueous decoction of Sanhuang Xiexin Decoction was eluted with macroporous resin to obtain the aqueous part,30%ethanol part,60%ethanol part and 95%ethanol part,and the aqueous decoction and the four eluted parts were subjected toα-amylase andα-glucosidase inhibition tests in vitro to screen the best active parts,and then analyzed the active components by high performance liquid chromatography,and the methodological investigations and content determinations were carried out.Results The best site for inhibitingα-amylase activity was screened to be the 30%ethanol site,with an IC_(50)of 1.707 mg·mL^(-1),and the active ingredients were baicalin,berberine,wogonoside,baicalein,aloe-emodin,rhein and emodin,with baicalin being the most abundant(177.588 mg·g^(-1)),and wogonoside being the second most abundant(30.546 mg·g^(-1));The best site for inhibition ofα-glucosidase activity was the 60%ethanol site with an IC_(50)of 0.0123 mg·mL^(-1),and the active ingredients were baicalin,berberine,wogonoside,baicalein,aloe-emodin,rhein,emodin,chrysophanol,and physcion,with baicalin being the most abundant(181.631 mg·g^(-1)),and berberine being second most abundant(71.724 mg·g^(-1)).Conclusion Sanhuang Xiexin Decoction has active inhibitory effect on bothα-amylase andα-glucosidase to a certain extent,and the inhibitory effect onα-glucosidase is better than that onα-amylase,which is of some reference value for the development ofα-glucosidase inhibitors.
