To study the chemical constituents in ethyl acetate extraction of Semen Litchi.
The compounds were isolated and purified by column chromatography on silica gel and Sephadex LH-20 coupled with preparative silica gel TLC, their structures were identified by physicochemical properties and spectrum analysis.
Five compounds were isolated and identified as stigmasterol (1), P-hydroxy-benzaldehyde (2), protocatechuic acid (3), daucosterol (4) and kaempferol-3-O-beta-D-glucopyranoside (5).
Compounds 2 and 5 are obtained from this plant for the first time.
研究荔枝核乙酸乙酯提取物中的化学成分。
采用硅胶柱色谱、Sephadex LH - 20柱色谱以及制备型硅胶薄层层析法进行分离纯化，通过理化性质和光谱分析鉴定化合物结构。
分离鉴定出5个化合物，分别为豆甾醇（1）、对羟基苯甲醛（2）、原儿茶酸（3）、胡萝卜苷（4）和山柰酚 - 3 - O - β - D - 葡萄糖苷（5）。
化合物2和5为首次从该植物中获得。
