| Abstract: | Diosgenin[(25R)-spirost-5-en-3 beta-ol] and cholesterol were detected as trimethylsilyl derivatives by gas chromatography-mass spectrometry in an alkaline lysate of a new hypotensive phospholipid from the lipid fraction of bovine brain. These steroids seemed to be present in the hypotensive phospholipid fraction in some bound forms. |
