养胃进食颗粒提取工艺研究

目的优选养胃进食颗粒的最佳提取工艺。方法采用正交试验设计，以养胃进食颗粒中药材的出膏率、浸出物及其主要有效成分橙皮苷的含量为指标，用多指标综合评分法进行数据处理，优选提取条件。结果最佳提取工艺为提取2次，第1次加10倍量水回流1．5h，第2次加8倍量水回流1h。结论优选出的养胃进食颗粒提取工艺合理、稳定、经济。

Study on Extraction Process of Yangwei Jinshi Granules

Objective To optimize the extraction process of Yangwei Jinshi Granules. Methods An orthogonal test was adopted in the study. With the paste-forming rate, the content of extract and the content of hesperidin of Yangwei Jinshi Granules as indices, data processing was carried out with grading method of synthesizing multiple indexes for optimizing the extraction condition. Results The best extraction technology was as follows： boiled 2 times, first with 10 times amount of water for 1.5 h, and then boiled with 8 times amount of water for 1 h. Conclusion The optimized process is reasonable, stable and economic for Yangwei Jinshi Granules.
