Major sterol composition of some algae from Qatar

Abstract

Thirteen macroscopic algae belonging to the three main divisions Chlorophyceae, Rhodophyceae and Phaeophyceae from the coast of Qatar (Arabian Gulf) were investigated for their sterol composition by using GC-MS coupling experiments. Our results show the sterol composition for these three major divisions of algae growing in this unusual condition of the sea water (salty, warm and shallow).
