Abstract
This thesis covers the phytochemical investi- gation of two Lupinus species (Lsguminosae), namely
L, albus and L. princei.

L. albus L. known locally as "Gebto" ( Amharic)
i9 a plant which grows widely in Gojjam province.
Chemical investigation of this plant afforded four
known isoflavonoids , namely genistein , 2'- hydroxygenistein
, 2* -hydroXydaidzein,
dzein is a new record for ’the Vf
L # princei Harms loyally * iV.nbvvn ' as "Dc^rgie^
Gerbie" (Oromo) is an indigenous, pTant 'which grows ! '
in Sidamo province. The phyt'ochemical investigation
of this plant was carried out for the first time
resulting in the isolation of 4 isoflavonoids and a triterpone. The compounds are genistein, 2'-hydro- xygenistein, luteone , 2‘ -hydroxyisolupslbigenin and
B-sitosterol , This is the second report of 2'-hydroisolupalbigenin
, which was recently ( 1909) discovered
to occur in the roots of L. albus.
The structures of the isolated compounds were
principally deduced by spectroscopic techniques.
