The dried olive leaves were extracted withmethanol: water (1:1 v\/v) or ethanol: water (3:1 v\/v) until complete extraction of phenoliccompounds had been achieved. The methanolic extract was then conducted to dryness, redissolvedin methanol and analyzed by TLC and RP-HPLC. There was no difference inqualitative phenolic profiles but, different levels of oleuropein were observed in thesedifferent varieties. The polyphenols that detected in olive leaf extract were: hydroxytyrosol, tyrosol, hydroxytyrosol glucoside, caffeic acid, elenolic acid derivatives, verbascoside, rutin, luteolin 7-O glucoside, and apigenin 7-O glucoside.The recovery of oleuropein was compared\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Hasan Fayadh Al-Azzawi, Sami Abdul Al-Mudhaffar Dr\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1511653868\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781511653862\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Createspace Independent Publishing Platform\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/09\/2015\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 234\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.84lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.61h x 6.69w x 0.49d","brand":"Hasan Fayadh Al-Azzawi","offers":[{"title":"Paperback","offer_id":47200772260095,"sku":"9781511653862","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_f40fe76c-340e-468d-8d71-cf1fd52db555.jpg?v=1756787813","url":"https:\/\/www.whiterainbookhouse.com\/products\/biochemical-and-biological-studies-on-hasan-fayadh-al-azzawi-9781511653862","provider":"WR Book House","version":"1.0","type":"link"}
