TRITERPENE ALCOHOLS AND 3-OXO STEROIDS OF 9 LEGUMINOSAE SEEDS

The seeds of nine Leguminosae plants were investigated for their trite rpene alcohol constituents. This led to the isolation and identificati on of 25 triterpene alcohols including one new compound, 24Z-ethyliden e-24-dihydroparkeol, and three series of skeletal double bond isomers of lanostane-type compounds, 9 beta,19-cyclolanostanes, and Delta(8)- and Delta(9(11))-lanostenes. The occurrence of eight 3-oxo steroids wa s also demonstrated. beta-Amyrin was the principal triterpene alcohol found in five of the Leguminosae seeds investigated.
