From the 75​% alc. ext. of Lupinus pubescens Benth herb 5 isoflavonoids were isolated and identified as genistein, luteone, 2'-​hydroxy genistein, genistein-​7-​O-​β-​glucoside and geneistein-​4'-​O-​β-​glucoside, in addn. to β-​sitosterol glucoside.  More over 3 quinolizidine alkaloids were isolated from the herb of the plant namely (+)​-​17-​oxosparteine, (+)​-​17-​oxolupanine and 5,​6-​dehydrolupanine.  The structure of the isolated compds. was established by spectroscopic methods, as well as comparison of the isolated alkaloids with authentic samples.
