Abstract:
Objective To optimize the extraction process for the effective fraction of Bushen Yizhi ( BSYZ) formula. Methods Yield of the effective fraction and contents of two marker compounds 2,3,5,4 -tetrahydroxystilbene-2-O-β-D-glucoside and osthole assayed by high performance liquid chromatography (HPLC) were used as the optimizing indexes, and weighted coefficient of the indexes was analyzed by analytic hierarchy process ( AHP). Ratio of liquid-to-solid, extraction time, and extraction times were used to screen the optimal conditions by orthogonal test. Results The optimized extraction process of the effective fraction of BSYZ formula was as follows: extracting with 8-fold water for three times, and boiling for 1.5 hours each time. The verification test showed that the comprehensive scores of the optimized extractive process were higher than those obtained in the orthogonal test. Conclusion The optimized extraction process and conditions are practical in the manufacture of the effective fraction of BSYZ formula.
