ABSTRACT
D (A:the amount of water added. B: the alcohol concentration in the fluidextract of herbs. C: decoction time, D: decoction times). The optimum decoction condition obtained was: adding water (12 times as much as medicine), decocting twice 1.5 hours each time, merging the filtrate, concentrating the merged filtrate into extract with a relative density of 1.20 (measured at 85℃), then adding alcohol slowly, and making the concentration of alcohol in the fluidextract come to 80%. Conclusion: The optimized process is stable and feasible.
