Abstract:
OBJECTIVE:To optimize water reflux extraction technology of Jiuwei yiwei mixture. METHODS:With the over-all score of the content of salvianoli acid B,a water-soluble component of the principal drug Salvia miltiorrhiza,the content of pae-oniflorin in Paeonia Radix Rubra and dry ointment yield rate as the observed index,and taking soaking time,extraction time, amount of water added,and extraction times as the factors,L9(34)orthogonal test was designed to optimize the extraction technolo-gy of Jiuwei yiwei mixture. And the verification test was conducted. RESULTS:The optimal technology was to add water with an amount 8 times as much as that of the drugs to soak them for 1 h and to conduct extraction twice,1 h for each. The overall scores of 3 batches of samples in the verification test were respectively 98.793,99.078 and 99.220(RSD<2%,n=3). CONCLUSIONS:The optimal technology for Jiuwei yiwei mixture is stable and feasible.
