ABSTRACT
To determine the process parameters of optimal water-extraction and ethanol precipitation method for Xuanbi'antong (XBF) extract, which is a clinically experience formula for coronary disease. Orthogonal test L9(34) was conducted for the study of XBF water-extraction and ethanol precipitation process. Extractum, salvianolic acid B, rhizoma coptidis alkaloid, paeoniflorin, puerarin, ginsenoside Rb₁, ginsenosides and echinacoside were selected as marker components and multi-index comprehensive weighted score was used to select and verify optimal water-extraction and ethanol precipitation process. The optimal extraction process was as follows: XBF was added with 10 times distilled water, decocted for half an hour for 3 times. The best ethanol-precipitation process was established where the ethanol was added up to 70% and precipitated for 24 hours in 1.12 extract density (20 ℃). The optimized water-extraction and ethanol precipitation method is stable and reliable, and can provide reference for further development and utilization of the formula.
