Abstract:
OBJECTIVE:To optimize the extraction technology of Zishen yangyin granules.METHODS:The yield of the extractum and the content of the extraction using 80% alcohol as solvent were used as indexes to optimize the extraction technology of Zishen yangyin granules by orthogonal experiment with the times of extraction,the extraction time and the amount of water added as factors.RESULTS:The optimal extraction conditions were as follows:the extraction was carried out for 3 times by adding water at an amount of 9 times,6 times and 6 times,respectively that of solid substance with decoction time of 3 h,2 h and 1 h,respectively.CONCLUSION:The optimal extraction process was proved to be time-saving and energy-saving and suitable for large production.
