[ 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

The structure of 1 was elucidated by spectroscopic methods including 2D-NMR techniques （COSY, HMQC, HMBC） and HR-ESIMS.展开更多

Bunge. METHOD: Various chromatographic techniques were employed for isolation and purification.RESULT: Seven compounds were isolated and their structures were identified as: kampferol-3-O-glucoside(Ⅰ), quercetin-3-O-glucoside(Ⅱ), p-hydroxybenzoic acid(Ⅲ), β-sitosterol(Ⅳ), daucosterol(Ⅴ), stigmasterol(Ⅵ),dotriacontanoic acid(Ⅶ). CONCLUSION: All of the above compounds were obtained from the Eritrichium genus for the first time.展开更多
