Asr. Anjaneyulu et al., A NEW SECOSTEROID FROM THE GORGONIAN SUBERGORGIA-SUBEROSA PALLAS OF THE INDIAN-OCEAN, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 36(5), 1997, pp. 418-423
An Indian Ocean gorgonian Subergorgia suberosa Pallas furnishes a new
secosteroid 4 along with a secosteroid 6, a trihydroxysteroid 5, a mix
ture of pregnane derivatives 2 and 3, a mixture of eleven monohydroxys
terols sand subergorgic acid 1, a tricyclicsesquiterpene acid. The str
ucture of the new secosteroid has been established as 3,9-dioxo-9,11-s
ecocholesta-5,7-dien-11-al by a study of its physical and spectral (UV
, IR, H-1 and C-13 NMR and Mass) data.
