摘要:

为了研究开心散的化学成分及体内代谢产物, 采用Agilent SB-C18色谱柱, 利用离子阱质谱及高分辨飞行质谱对开心散提取物及口服开心散后的大鼠血浆样品进行分析。从开心散提取物中共鉴定了39个化学成分, 包括11个人参皂苷, 14个远志皂苷, 5个远志多糖, 8个远志寡糖酯及1个远志口山酮, 其中15个化合物通过与对照品对照确定, 未检测到茯苓及石菖蒲的成分。大鼠灌胃给予开心散提取物后 (7 g/kg), 从血浆检测到10个人参皂苷和18个远志成分。本研究表明, 人参皂苷、远志皂苷及糖酯很可能是开心散的主要有效成分。

Abstract:

This work aims to elucidate the chemical constituents of Kai-Xin-San (KXS) and its metabolites in rat plasma. KXS extracts were separated on an Agilent HPLC SB-C18 column, analyzed by ion-trap tandem mass spectrometry and high-accuracy qTOF mass spectrometry in negative ion mode. A total of 39 compounds, including 11 ginsenosides, 14 Polygala saponins, 5 sucrose esters, 8 oligosaccharide esters and 1 xanthone were characterized from KXS. Fifteen of them were confirmed by reference standards. No constituents were detected from Poria or Acori Tatarinowii Rhizoma. After oral administration of KXS (7 g/kg), 10 ginsenosides and 18 Polygala compounds were detected in rat plasma. This study indicates that ginseng saponins, Polygala saponins and saccharide esters could be the major effective components of KXS prescription.
