Abstract
A new metamorphosis-enhancing macrodiolide, luminaolide (1), was isolated from the crustose coralline algae (CCA) Hydrolithon reinboldii. Its structure was determined by spectroscopic analysis. A fraction (1.30 mug/mL) eluted with 80% aqueous MeOH by ODS gel column chromatography of the same CCA extract induced larval metamorphosis (25.9 +/- 7.4%) against Leptastrea purpurea, and its metamorphosis-inducing activity was further enhanced to 92.6 +/- 2.9% with the addition of 1 (25.6 ng/mL).
摘要
从石状珊瑚藻（CCA）红鲍氏石枝藻中分离出一种新的促进变态的大环二醇类化合物，即发光内酯（1）。通过光谱分析确定了其结构。用相同的CCA提取物进行ODS凝胶柱色谱法，以80%甲醇水溶液洗脱得到的一个馏分（1.30微克/毫升）可诱导紫斑细指海葵幼虫变态（25.9±7.4%），加入1（25.6纳克/毫升）后其变态诱导活性进一步提高到92.6±2.9%。
