大孔吸附树脂富集纯化三七总皂苷工艺研究

Studies on Purification of Panax Notoginseng Saponins (PNS) with Macroporous Resin

摘要:

以三七总皂苷的洗脱率和精制度为考察指标,研究大孔树脂吸附法富集、纯化三七总皂苷的工艺条件及参数。结果表明:通过大孔树脂富集与纯化后三七总皂苷洗脱率达80%以上,50%乙醇洗脱液干燥后总固物中三七总皂苷纯度可达71.1%。采用此法可较好的纯化三七总皂苷。

Abstract:

The technical parameters of PNS's purification with macroporous resin were studied by monitoring the eluted ratio and purity of PNS.Over 80% of PNS was eluted from macroporous resin.The purity of PNS was up to 71.1% in the dried part of 50% ethanolic elution.This technique was a good method to purify PNS.
