[ Method ] Forty rats were randomly divided into two gToups: control group (distilled water) and trial group (water extract of 0. Kansuens/s) to carry out the acute toxicity experiment. The trial group was supplied with the maximum dose (6.0 g/ml,0.8 ml/20 g) twice per day for continuous 7 d. [Result] The maximal tolerance dose of rats to water extract of O. Kansuens/s was more than 480 g/kg. Feeding rats with O. Kansuens/s would not lead to the death of rats within short time (7 d) and no obvious macroscopic pathological changes in the viscera of rats could be seen in naked eyes. [Condusion] The study provided theoretical basis for full use of O. Kansuens/s resources.展开更多

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
