目的: 优选二母颗粒中知母的水提工艺。方法: 以HPLC测定知母皂苷B Ⅱ、芒果苷的含量及干膏收率为指标进行综合评价

采用正交试验法

考察溶媒用量、浸润时间、提取时间及提取次数等水提工艺参数。结果: 提取次数对水提工艺有显著性影响

确定较佳提取工艺为A1B1C1D3

即知母饮片加6倍量水

不浸泡

提取3次

每次30 min。结论: 该优选水提工艺稳定、合理可行。

Objective: To optimize water extraction process of Anemarrhena asphodeloides in Ermu granule. Method: With the content of timosaponin BⅡ

mangiferin and yield of dry extract as indexes to do comprehensive evaluation

orthogonal test was designed to investigate water extraction parameters

such as solvent usage

infiltration time

extraction time and extraction times. Result: Extraction times had significant effect on water extraction process

and optimum extraction process was A1B1C1D3

that A. asphodeloides pieces was added six times the amount of water without infiltration

extracted three times with 30 min each time. Conclusion: This optimized process was stable

reasonable and feasible.
