Embodiment 1
[0040] Take 1000g of Xanthos sorbifolia husks crushed into 20 meshes, use 10 times the volume of 50% ethanol, temperature 65°C, heat and reflux extraction 3 times for 3 hours / time, recover the solvent, and concentrate to obtain the extract After D-101 macroporous resin, eluted with water, 30% ethanol / water by volume, and 60% ethanol / water by volume as the elution solvent, heated to reflux, recovered the solvent under reduced pressure, and enriched 60% ethanol / water The eluate obtained the total saponins fraction of X. sorbifolium, and the solvent was recovered under reduced pressure, and placed at room temperature to obtain 92.0 g of total saponins of X. sorbifolium with a yield of 9.2%, wherein the saponin content was 73.5%.
Embodiment 2
[0042] Take 1,500 g of radix radix sorbifolia husks crushed into 30 meshes, use 8 times the volume of 70% ethanol by volume, and heat to reflux for extraction at a temperature of 70°C. The time is 2 hours / time, extract twice, heat to reflux, and recover the solvent under reduced pressure. The concentrated extract was eluted successively with HPD-100 macroporous resin, respectively with water, 40% ethanol / water by volume, and 80% ethanol / water by volume, and enriched by 80% ethanol / water washing. After decompression, the solvent was recovered under reduced pressure, and placed at room temperature to obtain 115.5 g of total saponins of X. sorbifolium. The yield was 7.7%, and the saponin content was 87.0%.
Embodiment 3
[0044] Take 1,500 g of radix sorbifolia husks crushed into 30 meshes, use 8 times the volume of ethanol with a concentration of 65% by volume, and heat and reflux at a temperature of 70°C for 2.5 hours / time, extract 3 times, heat and reflux, and recover the solvent under reduced pressure. The extract obtained after concentration is eluted with AB-8 macroporous resin, respectively, with water, 40% ethanol / water by volume, and 75% ethanol / water by volume as the elution solvent, and enriched by 75% ethanol / water for elution The solvent was recovered under reduced pressure, and placed at room temperature to obtain 130.5 g of total saponins of X. sorbifolium. The yield was 8.7%, and the saponin content was 83.5%.
