摘要: 用2D NMR技术研究了从绿茶中分离得到的4种儿茶素和2种鞣质,对其1H和13C NMR谱线作了全归属.

关键词: 茶多酚, 2D NMR

Abstract: Complete 1H and 13C NMR spectral assignments have been made by using H-H COSY, HMQC and HMBC techniques for active components extracted from green tea including (-) epicatechin (1),(-)-epigallocatechin (2), (-) epicatechin-3-O-gallate (3), (-) epigallocatechin-3-O-gallate (4), Theasinensin B (5)and strictinin (6).
