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
