摘要

目的：研究谷氨酸水解原人参二醇组皂苷制备人参皂苷Rg,3,的最佳工艺。方法：以谷氨酸为催化剂,原人参二醇(PPD)组皂苷为原料,通过单因素考察和正交试验对人参皂苷 Rg,3,的制备工艺进行优化,反应产物用 HPLC 进行定量分析。结果：正交试验优化结果表明,原人参二醇组皂苷(10 g/L)和谷氨酸(10 g/L)于 80 ℃反应 2 h,原人参二醇组皂苷被全部降解,人参皂苷 Rg,3,的转化率可达 65.12%。结论：该法操作简单,成本低,对环境无污染,是一种快速制备20(S)-Rg,3,和20(R)-Rg,3,的可行方法。

Abstract

Objective:To study the optimum process of ginsenoside Rg,3, prepared by hydrolysis protopanaxadiol-type saponins by glutamic acid. MethodsTaken glutamic acid as catalyst and protopanaxadiol(PPD)-type saponins as raw material,the preparation condition of ginsenoside Rg,3, was optimized by single factor investigation and orthogonal test,and the reaction products were quantitatively analyzed by HPLC. Results:The optimization results of orthogonal test showed that all PPD-type saponins were converted when PPD-type saponins (10 g/L) were hydrolyzed by glutamic acid (10 g/L) at 80℃ for 2 h,the conversion rate of ginsenoside Rg,3, was 65.12%. Conclusion:The method is simple in operation,low in cost with no pollution to environment,and is a feasible method for rapid preparation of 20(S)-ginsenoside Rg,3, and 20(R)-ginsenoside Rg,3,.
