Influence of Drying Temperature on the Effective Components of Yuanxiang Zhitong Pill

Abstract:

The influences of drying temperature 60℃ and 80℃ when in preparation of Yuanxiang Zhitong pill on its effective components were studied.The experimental results showed that the content of tetrahydropalmatine in the pill decreased by 13% when the drying temperature was 80℃,while its level had little decrement when the drying temperature was 60℃, and the higher drying temperature,the lower concentration of volatile oil in the pill.
