ALARIF, Walied M.; AYYAD, Seif-Eldin. N.  and  AL-LIHAIBI, Sultan S. Acyclic diterpenoid from the red alga Gracilaria foliifera. Rev. latinoam. quím [online]. 2010, vol.38, n.1, pp.52-57. ISSN 0370-5943.

The dichloromethane/methanol extract from the red alga Gracilaria foliifera was subjected to a column chromatography which afforded a new (naturally) acyclic diterpenoid 3,7,11,15 tetramethyl-3-hexadec-en-1-ol (1) in addition to two C29 ethylidene steroids fucosterol, (24E)-Stigmasta-5,24(28)-diene-3β-ol (2) and isofu-costerol, (24Z)-Stigmasta-5,24(28)-diene-3β-ol (3) which are reported for the first time from the genus Gracilaria. The structures were assigned mainly on the basis of 1H and 13C NMR experiments.

Keywords : Red Sea; Gracilaria foliifera; Acyclic diterpenoid; Fucosterol; Isofucosterol.
