Two new xeniolides from a Taiwanese Xenia soft coral

Nat Prod Res. 2007 Nov;21(13):1171-7. doi: 10.1080/14786410600906020.

Abstract

Chromatographic investigation of an extract of the octocoral Xenia umbellata afforded two new diterpenes, xenibelatols A (1) and B (2), in addition to three known xenicane diterpenes, 7,8-oxidoisoxeniolide (3), 9-hydroxyxeniolide F (4), and florlide C, and a cadinene sesquiterpene, xenitorin A (5). The structures were elucidated through spectroscopic analysis, especially 2D NMR.
