摘要：以儿茶素为标准品,采用Folin试剂分光光度法建立油橄榄叶中多酚的分析方法;以芦丁标准品为对照,建立油橄榄叶中黄酮的分析方法,研究不同树龄和干燥方式对油橄榄叶中黄酮和多酚含量的影响。结果表明:3年生油橄榄叶中黄酮和多酚的含量明显高于20年以上树龄的油橄榄叶。高温或阳光能降低黄酮和多酚的含量,采用大孔树脂精制油橄榄叶提取物,可获得多酚含量在80%以上的油橄榄叶提取物。
The analytical methods were established for polyphenols with catechin as standard contrast by Folin colorimetry and flavonoids with rutin as contrast, and the different factions on the contents of polyphenols and flavonoids were studied for tree age and dry style ;The results showed that the contents of polyphenols and flavonoids in 3 year old olive leaf were more high than that in 20 year old olive leaf of and high temperation or sunlight can reduce their contents. The extract of olive leaf was purified by macroporous resin. The content of total polyphenols of purified extract was over 80 %.
