Abstract
The steroidal composition of the sponge Artemisina apollinis from the Antarctic Ocean was studied by GC-MS and 'H NMR. The sponge contains twenty-eight C 25—C30 derivatives having four different types of nucleus: 3/3-hydroxy-5aH-, 3-keto-5aH-derivatives, 3/3-hydroxy-zl5-and 3/?-hydroxy-zl7-derivatives. Compounds with the first two nucleus are the most abundant, with similar side chain patterns and identical GC profiles. The 3-keto-5aH-derivatives constitute a new group of natural products.This publication has 1 reference indexed in Scilit:
