摘要: 研究灵芝中总三萜在大鼠体内的吸收情况。大鼠灌胃给予灵芝总三萜后, 利用HPLC-DADLC-MS方法鉴定大鼠血浆中的灵芝酸类成分。在大鼠血浆中检测到5种灵芝酸类成分, 即灵芝酸C2、灵芝酸C6、灵芝酸G、灵芝酸B和灵芝酸A。大鼠口服灵芝总三萜后灵芝中的灵芝酸类成分能被大鼠吸收。

Abstract: To investigate the absorption of total triterpenoids from Ganoderma lucidum in rats. HPLC-DAD and LC-MS methods were used to identify ganoderic acids in rat plasma after oral administration of total triterpenoids from G. lucidum by comparing their HPLC retention behaviors, UV absorption spectra, and mass spectra with authentic samples. Five ganoderic acids, ganoderic acid C2, C6, G, B and A were simultaneously detected in rat plasma. Ganoderic acids can be directly absorbed into circulation after oral administration of total triterpenoids from G. lucidum in rats.
