Abstract:
OBJECTIVE To optimize the water-extraction process of the Bushen Huoxue granules. METHODS Study the influence of extraction method, soaking time and extraction solvent consumption, extraction times, extracting time on the extraction process of the preparation with single factor experiment and orthogonal test, in which the transfer rate and the concentration in the extract of pinoresinol diglucoside, hydroxy safflower yellow A from Eucommia ulmoides, Safflower, respectively, by HPLC wave length switching, were taken as evaluation indexes, combined with the weight coefficient. RESULTS The better water-extraction process was that soaked 1 h with 12 times water, extracted three times, each time 1.5 h. CONCLUSION The water-extraction technology of granules is repeatable and feasible.
