| 摘 要： | Chemical investigation of L.sagitta afforded two new eremophilenolides, which were identified as 6β-angeloyloxy-10β-hydroxy-8 β-methoxy-eremophil-7(11)-en-12, 8α-olide (1) and 6β, 8β-dimethoxy-10β-hydroxy-eremophil-7(11)-en-12, 8α-olide (2). Their structures were estab- lished by spectroscopic methods including 2D NMR experiments.

| Abstract: | Chemical investigation of L.sagitta afforded two new eremophilenolides, which were identified as 6-angeloyloxy-10?hydroxy-8 ?methoxy-eremophil-7(11)-en-12, 8-olide (1) and 6? 8?dimethoxy-10?hydroxy-eremophil-7(11)-en-12, 8-olide (2). Their structures were estab- lished by spectroscopic methods including 2D NMR experiments. |
