Abstract:
Objective:To study the extraction process of Zhengtian Capsules (Radix Paeoniae Alba, Ramulus Vncariae cum Vnics, Rhizoma Chuanxiong, Herba Ephedrae, Herba Asari, etc.). Methods: Uniform design was used in the experiments, the alcoholic extract rate of the total alkaloid of Ramulus Uncariae cum uncis which was determined by titrimetric methods to evaluate the factor levels; and the water extraction process was studied by orthogonal design with the content of paeoniflorin which was determined by HPLC and with the yield of extracta sicca as the detective markers. Results: The optimum alcohol extraction factors were 8 times of 90% ethanol, infusing up to 72 hours. The optimum process of water decoction was to add 14 times amount of water, decocting for 3 times (2h, 1h, 1h in turn). Conclusion: According to the optimum extracting factors, the active substance can be extracted sufficiently.
