Abstract
Five new isoprenoids, 3,4,8,16-tetra-
-lobocrasol (
), 1,15β-epoxy-deoxysarcophine (
), 3,4-dihydro-4α,7β,8α-trihydroxy-Δ²-sarcophine (3),
-sarcophyolide E (4), and 16-deacetyl- halicrasterol B (5) and ten known compounds 6‒
, were characterized from the marine soft coral
, collected off Taitung coastline. Their structures were defined by analyzing spectra data, especially 2D NMR and electronic circular dichroism (ECD). The structure of the known compound lobocrasol (
) was revised. Cytotoxicity potential of the isolated compounds was reported, too.
