A new flavonoid 1 rhamnocitrin-3-O-(6"-femloyl)-β-D-galactopyranoside-4'-O-β-D- glucospyranoside called kansuensisoside A together with a known flavonoid 2 (rhamnocitrin- 3-O-β-D-galactopyranoside-4'-O-β-D-g...A new flavonoid 1 rhamnocitrin-3-O-(6"-femloyl)-β-D-galactopyranoside-4'-O-β-D- glucospyranoside called kansuensisoside A together with a known flavonoid 2 (rhamnocitrin- 3-O-β-D-galactopyranoside-4'-O-β-D-glucospyranoside) were isolated from the extract of the whole plant of Oxytropis kansuensis Bunge. The structure of 1 was elucidated by spectroscopic methods including 2D-NMR techniques (COSY, HMQC, HMBC) and HR-ESIMS.展开更多
A new iridoid glycoside 1 and a new iridoid 2 were isolated from the whole plant of Pedicularis kansuensis f. albiflora. Their structures were elucidated by spectroscopie methods.
