Abstract

The invention discloses pentacyclic triterpene saponin compounds with anti-breast cancer activity in spina gleditsiae and an extraction method thereof. The extraction method comprises the following steps: (1) grinding spina gleditsiae, and using an organic extracting agent to carry out heating reflux extraction and concentration to obtain a crude extract of spina gleditsiae; (2) dispersing the crude extract obtained in the step (1) into water, extracting the crude extract by petroleum ether and ethyl acetate in sequence to obtain a water phase, and concentrating the water phase to obtain a water phase part; (3) diluting obtained water phase part by water, making diluted water phase part go through an adsorbent resin chromatographic column to carry out adsorption, then eluting the adsorbent resin chromatographic column by an ethanol-water system in a gradient elution mode, and concentrating each elution part until no water is left; (4) making the 60% ethanol-water elution part go through a silica gel chromatographic column to carry out adsorption, and eluting the silica gel chromatographic column by a CH2Cl2-MeOH system in a gradient elution mode; and (5) making the elution part with a volume ratio of CH2Cl2 to MeOH of 1:1 go through a RP-C18 medium pressure chromatographic column, eluting the RP-C18 medium pressure chromatographic column by a methanol-water system in a gradient elution mode, and saving the 80% methanol-water elution part to prepare spina gleditsiae saponin A by using CH3CN / H2O (26:74 v / v).

Description

technical field [0001] The invention belongs to the technical field of saponins and preparation methods thereof, in particular to a pentacyclic triterpene saponins with anti-breast cancer activity in saponins and an extraction method thereof. Background technique [0002] Saponins are widely distributed in plants such as ginseng, Ophiopogon japonicus, Tianqi, Bupleurum, licorice and other marine organisms such as sea cucumbers and soft corals. According to the structure of aglycones, they can be divided into triterpenoid saponins and steroidal saponins. Among them, triterpene saponins are the most widely distributed, and can be divided into tetracyclic triterpene saponins and pentacyclic triterpene saponins, the latter being the most common. Triterpene saponins have good anti-tumor effects in vivo and in vitro, and their anti-tumor mechanisms are diverse. They can not only directly inhibit the growth of tumor cells, but also enhance the body's immunity, inhibit tumor invasio...
