Zhen Huifang, Xi Ping, Liu Zhongqiu, et al. Influence of Drying Temperature on the Effective Components of Yuanxiang Zhitong Pill[J]. Chinese journal of experimental traditional medical formulae, 1999, 5(2): 1-2.DOI:
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.
