Abstract
A newly described red alga, Helminthocladia nizamuddinii Afaq-Husain et Shameel (Liagoraceae, Bangophyceae) was collected from Paradise Point, near Karachi (Pakistan) during December 1988 and extracted in methanol. The extract revealed the presence of ten fatty acids (FAs) by GC-MS and six sterols by MS and 1H-NMR spectroscopy. Margaric acid (C17:0) was found in highest proportion, followed by stearic acid (C18:0). Palmitic (C16:0) and oleic (C18:1) acids also occurred in appreciable amounts, no plyunsaturated FA could be detected. Its sterol profile was found to consist of C28 to C30 containing compounds, no C27 sterol was detected. It is interesting that cholesterol and liagosterol were not present in the extract.
