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.
