第四节 黄酮类化合物的检识与结构鉴定

第四节 黄酮类化合物的检识与结构鉴定

第四节 黄酮类化合物的检识与结构鉴定. 目前主要采用的方法有: ①与标准品或与文献对照 PPC 或 TLC 得到的 Rf 或 hRf 值( Rf  100 )  ②分析对比样品在甲醇溶液中及加入诊断试剂后得到的 UV 光谱 ③ 1 H -NMR ④ 13 C -NMR ⑤MS. 一、色谱在黄酮类鉴定中的应用. 1. 纸层析 (PPC) 苷类成分可采用双向展开,第一相展开采用醇性溶剂,如 BAW 系统(正丁醇: 醋酸:水 4 : 1 : 5 上层);第二相展开用水性溶剂,如氯仿:醋酸:水( 3 : 6 : 1 ) 苷元则多采用醇性溶剂。
