Baoji Herbest Bio-Tech Co.,Ltd | Updated: Mar 23, 2020

The accuracy of the content determination of total flavones of epimedium (icarii) extract is very important to the quality standard of icarii.


"Pharmacopoeia of the People's Republic of China" in the method of determination of total flavonoids epimedium is mainly aimed at formulating, epimedium herbs in herb, toward the herb B, the herb under the condition of constant C content is not high, the error is small, but when the epimedium extract after purification. 


The herb, toward the herb B, the herb on C content of total flavonoids and huang, according to the pharmacopoeia method for epimedium glycoside of reference substance calculation error is large, because of improved method, the results can be seen from table 2, epimedium glycoside of molecular weight of the minimum in the four major components, than equivalent molecular quantity is small, so the pharmacopoeia method determination of epimedium flavonoids value is low, must be multiplied by the correction Factor correction.
