Asr. Anjaneyulu et al., RARE AROMADENDRANE DITERPENOIDS FROM A NEW SOFT CORAL SPECIES OF SINULARIA GENUS OF THE INDIAN-OCEAN, Tetrahedron, 53(27), 1997, pp. 9301-9312
Chemical examination of a new soft coral species of Sinularia genus of
the Indian Ocean resulted in the isolation of 4 new and rare aromaden
drane type of diterpenoids, in addition to the known Delta(9(15)) - af
ricanene, batyl alcohol and three polyhydroxy steroids. The structures
of new diterpenoids have been established by a study of their spectra
l data. The diterpenoids of this class have now been reported for the
first time from a marine organism, while they were reported only once
from a terrestrial source. The crude extract of the organism has showe
d moderate larvicidal activitiy. (C) 1997 Elsevier Science Ltd.
