VARIATION OF ALKALOID COMPONENTS OF LUPIN SEEDS IN 49 GENOTYPES OF LUPINUS-ALBUS L FROM DIFFERENT COUNTRIES AND LOCATIONS

Forty-nine genotypes of Lupinus albus seeds from different countries h ave been analyzed for their alkaloid content by thin-layer chromatogra phy and gas chromatography-mass spectrometry. Twenty samples were swee t, while 29 were bitter, and the taste was positively correlated with the alkaloid content. The composition of the-alkaloids showed that lup anine was the main alkaloid present, and variable amounts of albine, a lpha-isolupanine, multiflorine, and 13-hydroxylupanine were also detec ted in the seeds.
