Determination of depressor constituent sanggenon of Cortex Mori in different sources / 中成药

Objective:To study the contents and determinate method of Sanggenon C of Cortex Mori in different sources.Methods:Sanggenon C was determined by HPLC. The mobile phase was methanol water(75∶25). Detection wavelength was at 280nm.Results:The average recovery was 96.94% with RSD = 1.72% and the linear range was 0.32～4.80?g. The highest content of Sanggenon C was 0.55% and the lowest content was 0.02% from different producing area. Conclusion: The method is accurate and reliable with good reproducibility.
