| Based on the serum medicinal method, this study aims to investigate the migrating components of Yougui Yin in the blood after intragastric administration, and to provide reference for the basic research of its pharmacodynamics. The kidney deficiency rat model was replicated by adenine method. Normal rats and model rats were administered orally for a single gavage of Yougui Yin. The components in blood were rapidly analyzed and identified by ultra-high performance liquid chromatography/quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) and multiple reaction monitoring(MRM), and the migrating components in blood of Yougui Yin were explored by multivariate statistical analysis. The results showed that there were 42 characteristic peaks in the plasma of normal rats by UPLC-Q-TOF-MS technology and 13 chemical components were identified, including 6 alkaloids, 2 flavonoids, 2 triterpenoid saponins, 1 iridoid, 1 phenylpropanoid and 1 monoterpenoid. There were 22 characteristic peaks in the plasma of kidney-deficiency rats, and 12 chemical components were identified, including 2 iridoids, 6 alkaloids, 2 flavonoids, 1 monoterpenoid and 1 triterpenoid saponin. Verbascoside, isoacteoside, acteoside, pinoresinoldiglucoside, loganin and morroniside were identified by MRM both in the plasma of normal rats and kidney-deficiency rats. Compared with 85 monomer components in Yougui Yin, 17 common prototype components were found by UPLC-MS in the plasma of normal rats and kidney deficiency rats, including verbascoside, isoacteoside, acteoside, Rehmapicrogenin derived from Rehmanniae Radix Praeparata, pinoresinol diglucoside and geniposidic acid from Eucommiea Cortex, loganin and morroniside derived from Corni Fructus, mesaconine, benzoylmesaconine, benzoylaconitine, benzoylhypacoitine, mesaconitine, aconitine derived from Aconiti Lateralis Radix Praeparata, liquiritin, isoliquiritin and glycyrrhizic acid derived from Glycyrrhizae Radix et Rhizoma. Thirty-one metabolites of medicinal ingredients not found in the plasma of adenine-induced kidney deficiency rats were also detected in the plasma of normal rats. Twelve metabolites of medicinal materials not found in the plasma of normal rats were detected in the plasma of kidney deficiency rats. The results of the study provide reference for explaining the material basis and mechanism of Yougui Yin in the treatment of kidney deficiency. |
