基于UPLC-Q-TOF/MS分析止痛化徵胶囊的入血成分

Absorbed components analysis of Zhitong Huazheng Capsules in rat serum by UPLC-Q-TOF/MS

研究止痛化癥胶囊(ZTHZC)灌胃给予大鼠后的入血成分,为其药效物质基础研究提供参考。选取雌性Wistar大鼠为实验对象,灌胃给予ZTHZC,给药剂量为1.5 g·kg-1,收集血清样品,采用超高效液相色谱-四极杆飞行时间质谱联用(UPLC-Q-TOF/MS)技术与多元统计分析相结合的方法快速分析并鉴定吸收入血的原型成分。结果表明,在大鼠含药血清中共鉴定出15种入血成分,均为原型成分,分别为丹参素、丹酚酸A、B、C、D、9, 12-二羟基-15-十九碳酸、亚油酸、棕榈油酸乙酯、延胡索乙素、延胡索甲素,黄芪甲苷、黄芪皂苷Ⅱ、芒柄花黄素、刺芒柄花苷、木犀草素。该实验说明15种入血成分可能是ZTHZC在体内直接作用物质,为其药效物质基础研究提供科学依据。

To identify and analyze the constituents in rat serum after oral administration of Zhitong Huazheng capsule(ZTHZC), and provide a reference for its further research on pharmacodynamics material basis. Female Wistar rats were selected as experimental animals, and received intragastric administration of ZTHZC at a dose of 1.5 g·kg-1. After the serum samples were collected, the absorbed prototype components in rat serum were identified and analyzed by using ultra-high performance liquid chromatography-quadrupole-time-of-flight/mass spectrometry(UPLC-Q-TOF/MS) combined with multivariate statistical analysis.The results showed, a total of fifteen absorbed constituents were identified, all of which were prototype components, including Danshensu, salvianolic acid A, B, C, D, 9,12-dihydroxy-15-nonadecanoicacid, linoleic acid, ethyl palmitoleate, tetrahydropalmatine, fumarate A, astragaloside A, astragaloside II, saponin, locustin and luteolin. This experiment showed that these fifteen components absorbed into blood may be the potential bioactive components in ZTHZC, providing a scientific basis for clarifying its material basis in pharmacodynamics.
