| titleOfInvention | A kind of method that burdock seed oil, arctiin, arctigenin, arctigenin-4'-gentiobioside E and arctigenin-4'-gentiobioside H are separated from great burdock achene |
| abstract | The present invention provides a kind of method that burdock seed oil, arctiin, arctigenin, arctigenin-4'-gentiobioside E and arctigenin-4'-gentiobioside H are separated from great burdock achene, and the method first passes through CO 2 Supercritical fluid extraction carries out degreasing, isolated burdock seed oil and degreasing great burdock achene powder to great burdock achene, carries out water alcohol extracting to degreasing great burdock achene powder and is concentrated to give extraction medicinal extract, and CH is carried out to extraction medicinal extract 2 Cl 2 Extraction and upper silica gel column chromatography, arctigenin, arctigenin-4'-gentiobioside E, arctiin and arctigenin-4'-gentiobioside H are obtained using dichloromethane methanol gradient elution, and by thin-layer chromatographic analysis, purifying.The present invention can complete the separation of multi-products using a route of continous way, take full advantage of raw material, resource is saved, skimming processes do not pollute the environment, obtained burdock seed oil nutritive value is high, arctigenin, arctiin, arctigenin-4'-gentiobioside E and arctigenin-4'-gentiobioside H purity are high, can be applied to medicine food field individually or with other material mixings as raw material. |
