Objective To screen Danhe Granules for quality marker (Q-Marker) based on determination of plasma exposure of 15 characteristic components (salvianolic acid B, polydatin, emodin, emodin-8-O-β-D-glucoside, resveratrol, hyperin, isoquercitrin, astragalin, hesperidin, nobiletin, nuciferine, O-nornuciferine, N-nornuciferine, dehydronuciferin, and coclaurine) in Danhe Granules in rats. Methods EC-C18 column was used as pre-column, ZORBAX RRHD Eclipse Plus C18 column was used as column, 0.1% formic acid aqueous solution-acetonitrile was used as mobile phase, dynamic multiple response monitoring scanning mode was used for mass spectrometry and HPLC-MS/MS method was established. Rats were ig given Danhe Granules, plasma of rats at different time points were collected, concentration of each component in plasma samples of rats were determined, plasma exposure in vivo were calculated. Components with high exposure in vivo were determined, of which activity and preparation content were further analyzed. Q-Marker were determined according to amount of exposure in vivo, activity of high exposure ingredients, corresponding composition and content of the preparation. Results Plasma exposure levels of salvianolic acid B, polydatin, emodin, emodin-8-O-β-D-glucoside, hyperin, astragalin, astragalin, hesperidin, nobiletin, nuciferine, O-nornuciferine, N-nornuciferine, dehydronuciferin, coclaurine were (1340.45 ±167.64), (232.49 ±37.05), (677.51 ±71.61), (33.99 ±20.74), (281.53 ±32.32), (25.01 ±4.90), (16.85 ±2.88), (11.89 ±2.69), (113.71 ±23.05), (11.13 ±1.94), (168.69 ±42.68), (2595.00 ±314.78), (9.55 ±1.36), (1.29 ±0.11), and (13.96 ±0.88) ng∙h/mL, salvianolic acid B, polydatin, emodin, hyperin, astragalin, hesperidin, and nuciferine showed lipid-lowering activity and their contents in preparations were all greater than 0.1 mg/g. Conclusion Salvianolic acid B, polydatin, emodin, quercetin, hesperidin, naringin, and nuciferine can be used as Q-Marker of Danhe Granules.
