摘要: 为建立银杏叶提取物(GBE)中黄酮组分相似的、高含量的银杏叶黄酮提取物(GBFE)的工艺方案。筛选优化了二次聚酰胺柱层析工艺方案,得到了总黄酮含量>92%的GBFE,并开发了2″-(6″-p-香豆酰基-葡萄糖基-鼠李糖基)槲皮素(CGQ)为参照的紫外分光光度计计法检测总黄酮含量的方法。经二次柱层析,分别使用碳酸钠、乙醇洗脱,可去除大部分非黄酮物质,同时大部分黄酮成分保留。该方法得到GBFE总黄酮转移率>60%,黄酮部分与GBE相似度高。同时通过放大实验表明该工艺稳定性好,可进一步用于放大生产。

Abstract:

In order to obtain the high purity flavonoid and seamier composition Ginkgo leaves flavonoids extract (GBFE) from Ginkgo leaves extract (GBE).The UV spectrophotometer total flavonoids test method was built with 2″-(6″-p-coumaroylglucosyl) quercitrin(CGQ) as standard;Though twice polyamide column tomography process,the total flavonoids of GBFE is more than 92%.During the twice polyamide column method screened,Na2CO3 and ethanol solutions were chosen as eluent.And most impurities were separated with flavonoids.In this process,the total flavonoids recovery ratio is more than 60%,and similarity with GBE of flavonoids part.By the pilot experiments,the process is stability and suitable for production.
