Abstract

Two new genuine triterpenes previously semisynthesized and given the names dimethyl serratagenate and acetyl dimethyl serratagenate, besides three known coumaronochromones named lupinalbins A, C and E, in addition to three common Lupin isoflavones known as genistein, luteone and 2'-hydroxy genistein as well as, the more frequent β-sitosterol glucoside and the less frequent syringin were isolated from the chloroform fraction of the aerial parts of L. varius.
Moreover, the same compounds were almostly detected by co-chromatography with the corresponding fraction obtained from L. hartwegii. The identification of these compounds was based on different methods of chemical and spectral evidences.
