Phytochemical and pharmacological study on the rhizomes of Atractylodes lancea led to the identification of twenty-one compounds: six new eudesmane-type sesquiterpenoids (1-6), two new eremophilane-type sesquiterpenoids (7, 8), and thirteen known compounds (9-21). These new compounds were elucidated using extensive spectroscopic analyses with experimental and calculated electronic circular dichroism (ECD)
对白术根茎的植物化学和药理研究导致鉴定出二十一种化合物:六种新的eudesmane型倍半萜(1-6种),两种新的艾美碱型倍半萜(7种,8种)和十三种已知的化合物(9种) -21)。这些新化合物使用广泛的光谱分析方法进行了阐明,并通过实验和计算的电子圆二色性(ECD)进行了构型分配。值得注意的是,该研究是关于从白术属中分离出两种嗜闪灵型倍半萜类化合物(7、8)的首次报道。化合物5、7和16在浓度为10μM(双环醇为阳性药物)的情况下,对N-乙酰基-对氨基苯酚(APAP)诱导的HepG2细胞损伤显示出有效的肝保护活性。
