荔枝核的五个苷类成分

Five Glycosides from the Seeds of Litchi chinensis

通过溶剂分部和多种色谱分离,从荔枝(Litchi chinensis Sonn.)核中得到5个苷类成分。经光谱分析及与文献数据对照,分别鉴定为(-)-松脂素4-O-β-D-吡喃葡萄糖苷(1)、苯乙基β-D-吡喃葡萄糖苷(2)、乙基β-D-吡喃葡萄糖苷(3)、乙基α-D-吡喃葡萄糖苷(4)和胞苷(5)。它们均为首次从荔枝核中分离得到。

Five glycosides were isolated from the seeds of Litchi chinensis Sonn.by means of solvent fractionation and multiple chromatography.On the basis of spectral data,they were identified as（-）-pinoresinol 4-O-β-D-glucopyranoside（1）,phenylethyl β-D-glucopyranoside（2）,ethyl β-D-glucopyranoside（3）,ethyl α-D-glucopyranoside（4） and cytidine（5）.They were all isolated from litchi seeds for the first time.
