Abstract:
OBJECTIVE:To optimize the technics for the extraction of Qiangliyanhou mixture.METHODS:The physico-chemical properties of the compositions in the formula medicinal substances were analyzed,the obtained quantity of aqua aromatica was used as an investigation index of distillation technics;The preparation technics was optimized by orthogonal experiment in which the extraction ratio of the water extractives and the content of chlorogenic acid were used as the indexes to investigate the influence of the amount of water added,the soaking time before decoction,decoction time and times of decoc?tion on the extraction result.RESULTS:The optimized amount of aqua aromatica in the distillation procedures was collecting distillate that is3times the amount of the medicinal substances;The optimum water extraction condition was:the medicinal substances was soaked for2hours by adding15times amount of water before decocting for total3hours(3times?1hour/time).CONCLUSION:The preparation procedure is reasonable and reliable.
