Phenylacylated-flavonoids from Peucedanum chryseum

Abstract Phytochemical investigation of the methanol extract of the aerial parts of Peucedanum chryseum (Boiss. & Heldr.) D.F.Chamb., Apiaceae, led to the isolation of a dihydrofuranochromone, cimifugin ( 1 ); a phloroacetophenone glucoside, myrciaphenone A ( 2 ); and a flavonoid glycoside, afzelin ( 3 ) along with two phenylacylated-flavonoid glycosides: rugosaflavonoid C ( 4 ), and isoquercitrin 6″- O - p -hydroxybenzoate ( 5 ). The structures of compounds 1 – 5 were elucidated by extensive 1D- and 2D-NMR spectroscopic analysis in combination with MS experiments and comparison with the relevant literature. All compounds are reported for the first time from this species and compounds 2 , 4 , and 5 from the genus Peucedanum and from Apiaceae.
