Study on quality standard of Danmu exract syrup.

Objective: To establish the quality standard of Danmu exract syrup. Methods: TLC method was used to qualitatively identify Nauclea officinalis in Danmu exract syrup. The content of strictosamide and chlorogenic acid in Danmu exract syrup was determined by high efficiency axillary chromatography. Results: The spots were clear and there was no negative interference. The linear relationship of strictosamide was good in the range of 100~300ug/ml (R2=0.9997). The average recovery was 99.1% and RSD was 1.16%(n=9). Chlorogenic acid had a good linear relationship in the range of 6.7~20.2ug/ml (R2=0.9991). The average recovery was 99.9% and RSD was 1.10% (n=9). Conclusion: The standard is safe and reasonable, the method is simple, accurate and reproducible, and it can be used for the quality control of Danmu exract syrup. [ABSTRACT FROM AUTHOR]
