Objective:To establish quality standard of xiaojiean granules.METHODS:TLC was used to distinguish the caulis mahoniae and fructus forsythiae of xiaojiean granules. The RP-HPLC method was used to quantitative analysis the berberine of xiaojiean granules. RESULTS This method of qualitative distinguish is accurate and sensitive,Within the range of 0.0955μg~1.528μg,berberine presented a fine linear relationship between amount and peak area(r=0.9997),the recovery was 100.85%,RSD was 1.29%(n=5).CONCLUSION This me...
