Abstract

Abstract: 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%.

Key words: olive leaf, polyphenols, flavonoids
