Steroids from aquatic organisms: V. Main sterols of the fresh water snail, Biomphalaria tenagophila
The free sterols of the snail, Biomphalaria tenagophila, were isolated and characterized by means of gas chromatography and gas chromatography-mass spectrometry techniques. The mixture contains the common steroids found in freshwater molluscs, principally cholesterol. The presence of cholesta-5,7-di...
