苍耳子标准汤剂的质量标准研究OACSTPCD

Objective To establish the quality standard of Xanthii Fructs standard decoction.Methods According to the traditional decocting method,12 batches of Xanthii Fructs standard decoction were prepared,the range of the paste yield was determined,and the characteristic spectra of Xanthii Fructs standard decoction were established by HPLC.TLC was used for qualitative identification using chlorogenic acid and Xanthii Fructs as reference material.Results The extraction rate of 12 batches of Xanthii Fructs standard decoction ranged from 6.0%to 9.9%,with an average of 8.1%.10 common peaks were marked and 8 components were identified,namely,neochlorogenic acid(peak 2),chlorogenic acid(peak 3),cryptochlorogenic acid(peak 4),caffeic acid(peak 5),1,3-O-dicaffeoyl quinic acid(peak 6),isochlorogenic acid B(peak 7),3,5-O-dicaffeoyl quinic acid(peak 8),4,5-O-dicaffeoyl quinic acid(peak 10).TLC spots were clear,the separation degree was good,and the translational value was appropriate.Conclusion The established quality standard is reasonable and reliable,which can provide reference for the quality control of Xanthii Fructs formula granule.
