New Flavonoids from Artemisia frigida

New flavonoids were isolated from the aerial part of Artemisia frigida Willd. (Asteraceae). Their structures were elucidated using UV, IR, and NMR spectroscopy and mass spectrometry as chrysoeriol-7-O-(2 ′′-Oacetyl)-β-D-glucopyranoside (2′′-O-acetylthermopsoside), jaceosidin-4′ -O-β-D-glucopyranoside (isojaceoside), and 13 known flavonoids. The influence of the isolated compounds on α-glucosidase activity and triglyceride accumulation in 3T3-L1 preadipocytes was studied.
