[Methods] The quality evaluation method was established and validated with echinacoside as internal reference to determine the contents of other components(ferulic acid, salvianolic acid B, and icariin) according to the relative correction factor. The accuracy and feasibility of QAMS were evaluated by comparison on the results between the measured value and calculation value by external standard method and QAMS. [Results] A common pattern of characteristic fingerprint of Zhenrongdan mixture by HPLC was established. Thirteen common peaks were identified, and they account for 91% of the total peak area, and four components were verified in five batches of Zhenrongdan mixture. Good similarities with correlation coefficients higher than 0.99 were found in the fingerprints. There was no significant difference between the quantitative results of the four ingredients in the five batches by external standard method and QAMS. [Conclusions] The method of fingerprint combined with QAMS could be used for the quality control of multiple components determination and fingerprint chromatography for Zhenrongdan mixture.展开更多

S. Manso. [Methods]With ononin from O. turpethum as the internal reference, the five components were separated by HPLC, and the contents of various components were calculated according to the relative correction factors of ononin with caffeic acid, rutin, luteolin, and apigenin. Meanwhile, the calculated results of quantitative analysis of multi-components by single marker(QAMS) were compared with the determined values of the external standard method. [Results] The linear relationship of the five components in their respective ranges was good(r=0.999 9). The average recovery was in the range of 97.48%-101.05%, and the RSD values were in the range of 1.04%-2.71%. The results obtained by QAMS were close to those obtained by the external standard method. [Conclusions] The method is accurate, stable and adaptable, and can be used for the determination of five flavonoids in O. turpethum.展开更多
