Chemical investigation of L. tongolensis afforded two new eremophilenolides, which were identified as 3β-(2'-methylbutanoyloxy)-8βH-eremophil-7(11)-en-12, 8α(14, 6α)-diolide (1)and 8βH-eremophil-3, 7(11...Chemical investigation of L. tongolensis afforded two new eremophilenolides, which were identified as 3β-(2'-methylbutanoyloxy)-8βH-eremophil-7(11)-en-12, 8α(14, 6α)-diolide (1)and 8βH-eremophil-3, 7(11)-dien-12, 8α (14, 6α)-diolide (2). Their structures were established by spectroscopic methods including 2D NMR experiments.展开更多
