Yq. Wan et al., 2 NEW SCALARANE-TYPE SESTERTERPENES PHYLL ACTONE-H AND PHYLLACTONE-I FROM THE SPONGE PHYLLOSPONGIA SP, Gaodeng xuexiao huaxue xuebao, 17(11), 1996, pp. 1747-1749
Two new scalarane-type sesterterpenes namely phyllofolactones H(1), 1(
2) have been isolated from the sponge Phyllospongia sp. collected in t
he South China Sea, The structures of these compounds were elucidated
by interpretation of spectra data, The new sesterterpenes possess alph
a, beta-unsaturated gamma-lactone moieties and have hydroxyl groups at
taching the C-12 and C-16.
