The presence of Citrus aurantium L.(Ⅰ) and Rheum officinale Baiff.(Ⅱ)were identified by TLC for quality standard of QINGCHANG Mixture.The content of emodin
derived from Ⅱ
was assayed by TLCS.Results showed the negative comparison displayed no disturbance.The founded method showed linearity within the range of 0.228μg to 1.140μg.The average recovery rate was 100.9%
and RSD was 2.96%.The results indicate the method may be used for the quality control of the QINGCHANG Mixture.
