| titleOfInvention | A kind of acteoside and its method for separating and preparing |
| abstract | A kind of acteoside and its method for separating and preparing, are related to the separation of natural drug.Entitled 2 (3 ', 4 ' dihydroxy phenyl) ethyl O α L rhamnopyranosyls (1 → 3) β D (4 O coffee acyls) glucopyranosides of acteoside, molecular weight 624.59.Preparation method：Extracted after adding ethanol solution after the dry aerial parts of Macfadyena unguis-cati (L.) A. Gentry are crushed, suspended after leaching liquor is concentrated and dried with methanol solution is scattered, petroleum ether extraction is used again, water after methanol solution concentration after degreasing decoloring is diluted, through macroporous absorbent resin, impurity elimination is eluted with low-concentration ethanol solution, then eluted with high concentration ethanol；The eluent containing acteoside is collected, through reversed-phase silica gel column chromatography after concentration, with Methanol-water system gradient elution；Merge the elution fraction containing acteoside, the elution of methanol acetone system, be concentrated and dried the component rich in acteoside through the gels of LH 20 again after concentration, produce acteoside. |
