Objective To study the effect of Rougui (Cortex Cinnamomi) and Huanglian (Rhizoma Coptidis) with different proportions on the Cinnamaldehyde dissolution rate in Jiaotai Pill (Peaceful Interaction Pill).Methods The decoction method was used to prepare Rougui Decoction
No.2 Jiaotai Pill Decoction (Rougui:Huanglian=1:4) and reference standard stock solution of Cinnamaldehyde (0.2 μg/ml).The high performance liquid chromatogram of each sample was obtained with high performance liquid chromatography (HPLC) and the Cinnamaldehyde dissolution rate was calculated.Results The Cinnamaldehyde dissolution rate in No.1 Jiaotai Pill Decoction and No.2 Jiaotai Pill Decoction was 64.5% and 47.3% respectively when taking the Cinnamaldehyde dissolution rate in Rougui Decoction as 100%.Conclusion In Decoction of Jiaotai Pill
Huanglian can inhibit the dissolution of the active ingredient Cinnamaldehyde in Rougui.
