OBJECTIVE
To study the optimum extraction technology of total flavonoids from Flower of Eriobotrya japonica.
METHODS
To screen the best extraction technology by single-factor and orthogonal experiment according to the content of total flavonoids.
RESULTS
The optimum conditions were as follows: we extracted three times at 60 degrees C, each time for 1 h and the ratio of raw materials and solution was 1:10.
CONCLUSIONS
The extracting method is fit for the extraction of total flavonoids from Flower of Eriobotrya japonica. It can also provide a scientific basis for manufacture.
目的
研究枇杷花中总黄酮的最佳提取工艺。
方法
根据总黄酮含量，通过单因素和正交试验筛选最佳提取工艺。
结果
最佳条件如下：60℃提取3次，每次1小时，料液比为1:10。
结论
该提取方法适用于枇杷花中总黄酮的提取，也可为生产提供科学依据。
