From the aerial parts of Anthyllis hermanniae two new prenylated chalcones, 1-(2,4-dihydroxyphenyl)-3-[2,2-dimethyl-8-(3-methyl-2-butenyl)-2H-1-benzopyran-6-yl]-2-propen-1-one (anthyllisone) and 1-(2,4-dihydroxyphenyl)-3-[4-hydroxy-3-(2-hydroxy-3-methyl-3-butenyl)-5-(3-methyl-2-butenyl)phenyl]-2-propen-1-one (anthyllin), have been isolated, along with the known chalcones isobavachalcone and abyssinone VI and the prenylated isoflavonoids wighteone, lupiwighteone and lupalbigenin. Their structures were elucidated by spectroscopic methods, including 2D NMR techniques. D-Pinitol was also isolated.

Abstract
From the aerial parts of Anthyllis hermanniae two new prenylated chalcones, 1-(2,4-dihydroxyphenyl)-3-[2,2-dimethyl-8-(3-methyl-2-butenyl)-2H-1-benzopyran-6-yl]-2-propen-1-one (anthyllisone) and 1-(2,4-dihydroxyphenyl)-3-[4-hydroxy-3-(2-hydroxy-3-methyl-3-butenyl)-5-(3-methyl-2-butenyl)phenyl]-2-propen-1-one (anthyllin), have been isolated, along with the known chalcones isobavachalcone and abyssinone VI and the prenylated isoflavonoids wighteone, lupiwighteone and lupalbigenin. Their structures were elucidated by spectroscopic methods, including 2D NMR techniques. D-Pinitol was also isolated.File in questo prodotto:
