中文摘要：

采用硅胶、ODS和Sephadex LH-20等色谱技术，从枳棋子的体积分数为70％乙醇提取物的正丁醇萃取部位分离得到7个化合物，通过光谱数据和理化性质鉴定其化学结构，分别为：3’，5’-二-C—β—D-葡萄糖-根皮素（1），异牡荆素2＇-O-β—D-葡萄糖苷（2），牡荆素2＂-O-β—D-葡萄糖苷（3），异斯皮诺素（4），杨梅素3-O-β—D-葡萄糖苷（5），L-色氨酸（6）和五倍子酸（79化合物1-7均为首次从该植物分离得到．

英文摘要：

The chemical constituents from the seeds of Hovenia acerba were isolated by silica gel, ODS and Sephadex LH-20 columns in the present study. Seven compounds were obtained from the n-butanol fraction of the 70% extract, and their chemical structures were elucidated by their spectroscopic data and physicochemical properties as 3＇,5＇-di-C-β-D-glucopyranosyl.phloretin （1）, isovitexin 2＂-O-β-D-gluco- pyranoside （2）, vitexin 2＂-O-β-D-glucopyranoside （ 3 ）, isospinosin （4）, myricetin 3-O-β-D-glucopyranoside （5）, L-tryptophan （6） and gallic acid （7）. All compounds were isolated from this herb for the first time.
