Flavonoid glycosides and triterpenoids from Atractylis flava

摘要

Two new flavonoid glycosides, together with twelve known compounds including seven flavonoids and five triterpenoids were isolated from the whole plant Atractylis flava Desf. The structures of new compounds have been elucidated as 6-hydroxykaempferol6-methyl ether 7-O-beta-glucopyranuronoside (1) and isorhamnetin 3-0-[(6"'-0-E-feruloyl)-beta-d-glucopyranosyl-(l ->2)]-beta-d-galactopyranoside (2) named Atraflavoside A and B successively, on the basis of physical and spectroscopic analysis, includingID and 2D NMR (~1H, ~(13)C, COSY, TOCSY, HSQC, HMBC and NOESY) and mass spectrometry (HRESIMS) whereas those of the known compounds (3-14) were established by spectral comparison with those published in the literature.
