摘要

目的: 探索果胶酶法提取翠云草中总黄酮的工艺条件。方法: 以总黄酮提取率为指标

选取酶用量、酶解时间、pH值及酶解温度为影响因素

采用紫外分光光度法测定总黄酮含量

通过L9(34)正交试验优选总黄酮的提取工艺。结果: 最佳提取工艺条件为果胶酶质量浓度0.075 g·L-1

酶解时间2.5 h

酶解pH 5.0

酶解温度50 ℃

总黄酮平均提取率1.40%。结论: 优选的提取工艺稳定可行

且较大地提高了提取效率

为翠云草药用价值的进一步开发提供实验依据。

Abstract

Objective: To explore extraction process conditions of total flavonoid in Selaginella uncinata by pectinase enzymatic method. Method: With extraction ratio of total flavonoid as index

L9 (34) orthogonal test was token to optimize extraction technology of total flavonoid with pectinase dosage

enzymatic hydrolysis time

pH and enzymatic hydrolysis temperature as factors.The content of total flavonoid was determined by UV. Result: Optimum extraction technology conditions were as follows:the concentration of pectinase 0.075 g·L-1

enzymatic hydrolysis time 2.5 h

hydrolysis pH 5.0

extraction temperature 50 ℃

under these conditions

average extraction ratio of total flavonoid 1.40%. Conclusion: Optimized extraction technology was stable and feasible with high extraction efficiency

it provided experimental basis for further development of S. uncinata.
