DETERMINING THE CONTENT OF JASMINODIN IN MEI RONGCAPSULE WITH THIN LAYER CHROMATOGRAPHY

Objective Jasminodin in Mei Rong capsule was determined by the method of thin layer chromatography. Methods The sample jasminodin was extracted with methanol and then the extract was chromatographed on silica gel GF254 plate with chloroform-methanol-water (10:3:1) as mobile phase and the chromatograms were scanned by using Shimadzu CS-930 dual wavelength TLCS in zegzag scanning mode at λs 370nm and λR 250nm.Results Calibration graph was rectilinear between 2.7μg～16.2μg per spot for the jasminodin. Conclusion Satisfatory results were obtained with the average recovery ratio of 99.76% ,RSD 2.27%.
