| titleOfInvention | Steroid saponin compound and preparation method and application thereof |
| abstract | The invention discloses a steroid saponin compound and a preparation method and application thereof, wherein, polygonatum is mixed with an aqueous solution of ethanol for extraction, filtered and concentrated by an ultrafiltration membrane and a nanofiltration membrane device, then adsorbed by a macroporous resin column, eluted by the aqueous solution of ethanol, concentrated and recycled by ethanol, and then the steroid saponin extract is obtained by freeze drying or spray drying. The steroid saponin extract is separated by using a medium-low pressure liquid chromatography equipped with an OSD column, and is subjected to gradient elution by using an aqueous solution of methanol with the volume concentration of 10-100 percent, and is purified by a preparative reverse phase high performance liquid chromatography to obtain eight steroid saponin compounds. The method is simple to operate and easy to industrially popularize. |
