Objective:To establish the quality specification of Zishen capsules.Methods: Emodin in Zishen Capsules was determined by TLC-Scanning.The samples were separated on a silica gel plate with a mixture of n-hexane-ethylacetateformic acid(30∶10∶0.5) as the developing system.The detection wavelength was 442 nm
the reference wavelength was 610 nm.Radix Paeoniae Alba
Caulis Polygoni Multiflori
Bulbus Lilii in the capsule were identified by TLC.Results:The calibraction curve was linear in the range of 0.04~0.20μg
r=0.995
the average recovery was 98.1%
RSD=2.26%;the chromatographic spots were clear
without interference and easy to recognize.Conclusion:The method is accurate
simple and reproducible.It could be used for the quality control of Zishen Capsules.
