Lipids and coumarins of astragalus trigones and rhynchosia minima

The aerial parts of both Astragalus trigonus DC. and Rhynchosia minima L. [Fam. Leguminosae] were exhaustively extracted with ethanol [90%] and fractionated into coumarin and unsaponifiable fractions. The coumarin fraction of A. trigonus was found to contain bergapten [I] and xanthotoxin [II], whereas waxy hydrocarbons, beta-amyrin [III] and beta-sitosterol [IV] were isolated from the unsaponifiable fraction. The coumarin fraction of R. minima was found to contain bergapten [I], isopimpinellin [V] and umbelliferone [VI], whereas waxy hydrocarbons and beta-sitosterol [IV] were isolated from the unsaponifiable fraction. Also, the fatty acids of both plants were studied by GLC of their methyl esters
