Abstract:
OBJECTIVE:To establish the quality standard of shuangbai tincture.METHODS:The rhubarb and cortex phellodendri in shuangbai tincture were identified qualitatively by TLC.The content of emodin in this preparation was deter-mined by HPLC.RESULTS:In the TLC of the testing samples,the corresponding positions of standard rhubarb and standard cortex phellodendri respectively showed the same color of speckles.The linear range of emodin was0.1176?g～2.3520?g(r=0.9994)and the average recovery was98.81%(RSD=0.45%).CONCLUSIONS:This method is simple,accurate and repro-ducible,and suitable for the quality control of shuangbai tincture.
