Three new isoflavonoid glycosides from Lupinus luteus and L. polyphyllus x arboreus

, p. 394 - 396 (1993)
As part of our studies on leguminous plants, we examined the ingredients of Lupinus luteus L. and L. polyphyllus x arboreus hybrid, and three new isoflavonoid glycosides together with six known ones were isolated. They were determined to be 8-C-glucopyranosylgenistein 4'-O-glucopyranoside (1), 5-O-methylgenistein 4', 7-di-O-glucopyranoside (2), 2'-hydroxygenistein 4', 7-di-O-glucopyranoside (3) by spectroscopic and chemical methods. It was also shown that the isoflavonoid distributions in the two species were differed.

experimental part, p. 8654 - 8658 (2011/12/01)
The pyranocoumaronochromone lupinalbin H was synthesized in three major steps, which involved preparation of 2′-hydroxygenistein by the Suzuki-Miyaura reaction, followed by oxidative cyclodehydrogenation into lupinalbin A. The final step was the regiospec

In addition to 5-O-methylgenistein (1), a further investigation of the isoflavonoid constituents in roots of the yellow lupin (Lupinus luteus L. cv.Barpine) has yielded five new 5-O-methylisoflavones named barpisoflavone A (2), 5-O-methyl-lupiwighteone (3
