摘要
油橄榄叶主要含有橄榄苦苷、黄酮和多酚等抗氧化物。本研究以引种的希腊油橄榄阿斯为原料,采用乙醇-水(体积比60∶40)对油橄榄叶进行提取,依次用石油醚和乙酸乙酯萃取,乙酸乙酯萃取相经过硅胶柱层析,再用HPLC制备色谱,得质量分数95%以上的单体,通过IR、UV、MS、NMR鉴定该化合物为橄榄苦苷。橄榄苦苷经过酸水解,得到两个主要产物,一个为羟基酪醇,另一个为榄香酸。
There are many antioxidants in olive leaves such as oleuropein, flavonoids and polyphenols. Leaves of Ascolano olive introduced from Greece were successively extracted with EtOH-H2O（60：40） , petroleum ether and ethyl acetate. The ethyl acetate fraction was subjected to silica gel column chromatography, then treated with preparative HPLC to obtain a compound with content of 95 %, which was identificated to be oleuropein by UV, IR, MS and NMR. Oleuropein could be acidically hydrolyzed to give hydroxytyrosol and elenolic acid as main .
