| Abstract: | Objective To establish a method for determination of chrysophanol,emodin and rhein in Huangzhi capsules.Method Chrysophanol,emodin and rhein in Huangzhi capsules was determined by TLC-scanning with a mixture of n-hexane-ethylacetate-formic acid（30∶10∶0.5） as the developing system.The detection wavelength was 435 nm and 610 nm.Results The calibraction curve of chrysophanol,emodin and rhein was linear in the range of 0.014 65～0.073 25,0.013 35～0.066 75,0.012～0.072 μg respectively.Conclusion The method was simple, accurate with good repeatability, and suitable for the content determination of chrysophanol, emodin and rhein in Huangzhi capsules. |
