indicated that the efficacy of QYD might be attributed to heat-transformed products of swertiamarin (HTPS). Further investigation on HTPS led to the isolation of sweritranslactone D (1), a novel secoiridoid dimer possessing a tetracyclic lactone skeleton, with better hepatoprotective activity than N-acetyl-L-cysteine in vitro.
青叶胆,被称为庆叶丹(清胰汤),已被记录在中国药典治愈肝炎。有趣的是,在煎剂中检测不到其宣布的主要活性成分,药草苷,这表明 QYD 的功效可能归因于药草苷的热转化产物(HTPS)。对 HTPS 的进一步研究导致分离出 sweritranslactone D ( 1 ),一种具有四环内酯骨架的新型二聚环烯醚萜酯,在体外具有比N-乙酰基-L-半胱氨酸更好的保肝活性。
