Objective To establish a HPLC-QAMS method for simultaneous determination of notoginsenoside R1, ginsenoside Rg1, ginsenoside Rb1, 3'-hydroxy puerarin, puerarin, 3'-methoxy puerarin, senkyunolide A, ligustilide, tetrahydropalmatine, dehydrocorydaline, corydaline, notopterol and isoimperatorin in Jingtong Granules, and to analyze and evaluate the content detecting results of 13 components by grey relational analysis. Methods The chromatographic column Shimadzu C18 was used. And using acetonitrile-0.1% phosphoric acid as mobile phase with gradient elution. The detection wavelength were 203 nm for notoginsenoside R1, ginsenoside Rg1, ginsenoside Rb1, 280 nm for 3'-hydroxy puerarin, puerarin, 3'-methoxy puerarin, senkyunolide A, ligustilide, tetrahydropalmatine, dehydrocorydaline, corydaline and 315 nm for notopterol and isoimperatorin. The contents of 13 components were determined by external standard method (ESM). Taking puerarin as internal standard substance, the relative correlation factor (f) of notoginsenoside R1, ginsenoside Rg1, ginsenoside Rb1, 3'-hydroxy puerarin, 3'-methoxy puerarin, senkyunolide A, ligustilide, tetrahydropalmatine, dehydrocorydaline, corydaline, notopterol and isoimperatorin was calculated, and the contents of 12 components were calculated. The differences between the content detecting results by ESM and HPLC-QAMS method were compared. Based on the grey relational degree, the HPLC-QAMS method conent detection data of 13 component of different batches of Jingtong Granules were analyzed, and the sample of 15 batches of Jingtong Granules was comprehensively quality evaluated. Results Notoginsenoside R1, ginsenoside Rg1, ginsenoside Rb1, 3'-hydroxy puerarin, puerarin, 3'-methoxy puerarin, senkyunolide A, ligustilide, tetrahydropalmatine, dehydrocorydaline, corydaline, notopterol and isoimperatorin had good linearity in their respective ranges (r ≥ 0.999 2). The average recoveries of the 13 components (n = 9) were between 96.86%—100.37% with the relative standard deviations less than 1.65%. The established RCF had good durability, and the results calculated with HPLC-QAMS method were consistent with the results by the ESM. The results of grey correlation analysis showed that the relative correlation degree of 15 batches of Jingtong Granules was 0.332 4—0.600 4, indicating that there was a certain quality difference between batches of Jingtong Granules. Conclusion HPLC-QAMS multi-index component quantitative control combined with grey relational analysis is convenient and accurate, and can be used for the comprehensive quality evaluation of Jingtong Granules.
