摘要: 用正交试验和单因素试验考察了索氏提取不同有机溶剂萃取法;不同条件乙醇回流提取法和超声提取法对云南栘依总黄酮含量的影响,结果表明:正丁醇萃取法总黄酮含量明显高于乙酸乙酯萃取法;回流提取,以12倍量75%乙醇回流提取1.5h,2次为最佳条件;超声提取以60min为宜。

Abstract: The optimum extracting conditions of flavones in Yunnan Docynia delavayi (Franch.) Schneid were investigated by single factor experiment with the orthogonal experimental design. The results showed that various methods have different effects on extraction rate of flavones. In the Soxhlet extraction, the extraction rate is high when n-butanol is used as solvent extracts. In the back-flow, 12:1 of 75% ethanol to Yunnan Docynia delavayi (Franch.)Schneid weight, extracted 2 times and 1.5h for each time are optimal. In the 60% ethanol ultrasonic extract, the extraction time 60min is optimal.
