Xenia macrospiculata

Xeniolides A (152) and B (153) are a pair of lactones, related to the prenylated caryophyllene xeniaphyllenol and xenicin, which have been isolated from the soft coral Xenia macrospiculata. Hydroxydilophol (154) is a germacrene-like diterpenoid which has been obtained from the brown alga Dictyota masonii. The full paper, including an X-ray analysis, has appeared on dictyodial and dictyolactone which were obtained from various Dictyota and Aplysia species. A... 

There have been no natural products investigations of soft corals from the cool temperate west coast of southern Africa. Soft corals are common along the south-east coast of South Africa and as part of our ongoing search for bioactive metabolites from the marine invertebrate fauna of the Tsitsikamma Marine Reserve we isolated four bioactive xenicane diterpenes, the tsitsixenicins A - D (93 - 96) from the endemic soft coral Capnella thyrsoidea (Family Nephtheidae) [91]. The structures of 93 -96 were delineated from standard analysis of their NMR data and comparison of these data with those published for related compounds e.g. 9-deacetoxy-14,15-deepoxyxeniculin (diastereomic with 93) isolated from the Red Sea soft coral Xenia macrospiculata [92].
