Abstract:
Objective To optimize the extraction conditions of volatile oil from Angelica Sinensis and Cassia Bark in Wenyang purgation granules.Methods The volatile oil was extracted from Angelica Sinensis and Cassia Bark by the method of steam distillation light oil device with diethyl ether extraction. The yield of the volatile oil was chosen as the evaluation index. The time of dip in water, the ratio of water to herbal medicine material and the time of distillation were used as the main factors. The optimum extraction conditions were investigated by the L9(34) orthogonal design. Results The optimal conditions for extraction process of volatile oil from Angelica Sinensis and Cassia Bark in Wenyang purgation granules were as follows:the time of dip in water was 3 h;the ratio of water to herbal medicine material was 10∶1;the time of distillation was 6 h. Conclusion The optimized conditions of extraction process are stable and feasible.
