Clear differences were found when comparing the chemical content of the northern, Gulf of Eilat, to the southern-central, Dahlak archipelago, Red Sea sponge Siphonochalina siphonella. The Dahlak sponge was found to be richer in the more polar triterpenes. Nine new compounds (1-4, 7, 8, 15-17) were isolated and identified, among them two sipholane glycosides, sipholenoside A and B (7 and 8), and one compound, dahabinone A (17), possessing a new skeleton.
在比较红海埃拉特湾北部的海绵Siphonochalina siphonella与中南部达拉克群岛的海绵的化学成分时,发现了明显差异。研究发现,达拉克海绵中极性更强的三萜类物质含量更高。分离并鉴定出9种新化合物(1-4、7、8、15-17),其中包括两种西佛烷糖苷,即西佛诺苷A和B(7和8),以及一种具有新骨架的化合物——达哈宾酮A(17)。
