To study the chemical constituents of polyphenols in seed of Litchi chinensis.
The seeds of Litchi chinensis were extracted by 65% ethanol, then the compounds were separated by repeated silica gel, polyamide and preparative TLC. The structures of polyphones isolated were identified by analysis of their spectral datas and chemical properties.
Four polyphones compounds were isolated as protocatechuic aldehyde (I), protocatechuic acid (II), daucosterol (III) and (-) -epicatichin (IV).
Compounds I , III and IV are isolated from this plant for the first time.
研究荔枝种子中多酚类化学成分。
用65%乙醇提取荔枝种子，然后通过反复硅胶柱色谱、聚酰胺柱色谱及制备薄层色谱分离化合物。通过光谱数据分析和化学性质鉴定所分离得到的多酚类化合物的结构。
分离得到4种多酚类化合物，分别为原儿茶醛（I）、原儿茶酸（II）、胡萝卜苷（III）和（-）-表儿茶素（IV）。
化合物I、III和IV为首次从该植物中分离得到。
