Description From lipid fraction of frozen samples of Sargassum johnstonii unsaponifiable part was extracted with diethyl ether to isolate total sterols. The extracted sterols were obtained for a period of nine months and tested against test bacteria. The extracts from June to October months showed antibacterial activity while the samples from November to January and May did not show any activity over the test bacteria Proteus vulgaris a gram-negative organism which has shown high sensitivity towards the samples from June and October
