Abstract
Objective The fingerprint method based on high-performance liquid chromatography for the quality control of bidens bipinnata L were firstly described and optimized. Methods HPLC system was used to obtain the fingerprint spectrum of bidens bipinnata L. The chromatography condition was ODS C18 column (4. 6mm×255mm,25μm),mobile phase Methanol-0. 2% HAc,and flow speed 1. 0ml ? min-1, detection wavelength 363nm.Results In this experiment,the standard fingerprint had been established and the similitude degree of 10 batches bidens bipinnata L. has also been obtained(0.941～0.999). Conclusion The method was accurate,reliable,good reproducibility, strong characteristic and could be used for the standard of general judgement and the quality estimation about the bidens bipinnata L. Key words: Bidens; HPLC; Fingerprint
