南山茶籽中新发现的一个乙酰基黄酮苷的核磁结构解析
Structure determination on a new acetyl flavonoid glycoside in seeds of Camellia semiserrata Chi.by NMR spectroscopy
摘要
Abstract
A high-purity compound was extracted by solvent extraction, liquid-liquid separation, silica gel chromatography and high-performance liquid semi-preparative chromatography by using seeds of Camellia semiserrata Chi.as raw materials.The compound was identified as kaempferol-3-O-[α-L-rhamnopyranosyl-(1-3)-2,4-di-O-acetyl-α-L-rhamnopyranosyl-(1-6)]-β-D-glucopyranoside, an acetyl flavonoid glycoside, by physical and chemical properties, mass spectrometry and nuclear magnetic resonance.Two-dimensional nuclear magnetic resonance (2D-NMR) techniques including H-H COSY, HSQC, HMBC and TOCSY were used to affiliate its 1H and 13C NMR chemical shift and explain the structure.关键词
