| titleOfInvention | The preparation of high purity Herba Cleidion brevipetiolae glycosides A and quality controlling means thereof |
| abstract | A kind of with Euphorbiaceae Cleidion plant leaf of Cleidion brevipetiolatum Pax et Hoffm for raw material, the preparation method of a kind of high purity Herba Cleidion brevipetiolae glycosides A, detection method and purposes are provided, its method is: first pulverized by euphorbia plant leaf of Cleidion brevipetiolatum Pax et Hoffm, and extract with alcohol heating reflux, ethanol extraction is through silica gel column chromatography, with chloroform-methanol mixed solvent wash-out, detect with thin-layer chromatography, collect the elutriant containing Herba Cleidion brevipetiolae glycosides A, merge, concentrating under reduced pressure, obtains Herba Cleidion brevipetiolae glycosides A coarse crystallization; Be separated with reverse phase silica gel C-18 Column preparation high-efficient liquid phase technique again, analysis mode high performance liquid chromatography is utilized to detect to collected every a elutriant, merge the identical and purity of retention time between weight 90% ~ 98% and the Herba Cleidion brevipetiolae glycosides component A of more than 98%, concentrating under reduced pressure, the Herba Cleidion brevipetiolae glycosides component A that the Herba Cleidion brevipetiolae glycosides A of purity between weight 90% ~ 98% and purity are greater than 98% can be obtained respectively, and adopt thin-layer chromatography and liquid chromatography to carry out quality control. |
