| titleOfInvention | The Pentacyclic triterpene saponins compounds and its extracting method of anti-breast cancer activity in a kind of spina gleditsiae |
| abstract | The invention discloses the Pentacyclic triterpene saponins compounds and its extracting method of anti-breast cancer activity in a kind of spina gleditsiae, its extracting method comprises the following steps：1）After spina gleditsiae pulverizing medicinal materials, after organic extractant heating and refluxing extraction, concentration, spina gleditsiae crude extract is obtained；2）By step 1）In obtained spina gleditsiae crude extract be dispersed in water, and extracted successively with petroleum ether and ethyl acetate, obtain aqueous phase, aqueous phase position is obtained after aqueous phase is concentrated；3）Adsorbed after obtained aqueous phase position is diluted with water by polymeric adsorbent chromatographic column, then use ethanolic aqueous system gradient elution again, each elution fraction is concentrated to dryness；4）By 60% ethanol water elution fraction, after crossing silica gel column chromatography absorption, CH is used 2 Cl 2 MeOH systems carry out gradient elution；5）By CH 2 Cl 2 MeOH volume ratios are 1:1 elution fraction crosses RP C 18 After middle compression leg chromatogram, gradient elution is carried out using methanol aqueous systems, by 80% methanol water elution position CH 3 CN /H 2 O (26:74, v/v) prepared, obtain spina gleditsiae saponin A. |
