摘要
目的 研究螯合树脂D751和D403用于脱除银杏叶提取液中重金属离子的可行性和适应性.方法 在工业模式中药自控提取平台上进行脱重金属实验,以提取物得率、银杏总黄酮含量、HPLC图谱相似度和重金属脱除率为考察指标,比较两种树脂对有关指标的影响.结果 D751和D403树脂用于银杏叶提取物脱重金属,得率损失均小于6%,脱重金属提取物中重金属含量低于国家限量,脱重金属提取物和未脱重金属提取物的HPLC图谱相似度均大于0.98,提取物中银杏总黄酮损失率小于5%.结论 树脂D751和D403都适用于脱除银杏叶提取液中的重金属离子.
Abstract
Objective To study the feasibility of using chelating resins D751 and D403 to remove the heavy metals from the extracts of Folium Ginkgo (FG). Methods Heavy metal removal experiments were performed on automatic control platform in industry mode. With dry ointment yield, total content of flavones, comparability of HPLC and removal rate of heavy metal as the indexes, the effects of two kinds of chelating resins on removing heavy metal were compared. Result After removing heavy metal by resins D751 and D403, the loss rate of the dry extract were less than 6 % , and the heavy metal contents were lower than national limits; HPLC similaritites were higher than 0. 98, and the loss rates of total flavones were less than 5%. Conclusion Chelating resins D751 and D403 can be used to remove heavy metal from extracts of Folium Ginkgo.
