Oxygen Radical Absorbance Capacity (ORAC)
-Keupayaan Menyerap Radikal Bebas

Kajian Saintifik yang dilakukan di negara Australia, Europah, Amerika Syarikat membuktikan Keupayaan Penyerapan Radikal Bebas.

400% Melebihi Vitamin C
76% Melebihi Teh Hijau
67% Melebihi Biji Anggur
700% Melebihi Jus Manggis
Kajian Klinikal di R Clinic di Budapest-Hungary mendapati Ekstrak Daun Zaitun telah menolong 90% daripada 164 pesakit yang mengalami masalah pernafasan & paru paru (batuk,selsema,flu & asthma) Aziz et...,43"
Pada tahun 1969, Kajian Sains oleh Dr. Renis dari Syarikat Farmaseutikal terbesar di Amerika (UpJohn Pharmaseutical) bahawa ekstrak Daun Zaitun (Elenolic Acid) mampu menghalang pembiakan virus. Renis HE, 1970; 167-72
Pada tahun 1992,ahli Biologi Perancis membuat kajian klinikal di Laboratoire de Pharmacognosie mendapati aktiviti virus dapat direncat atau dimusnahkan oleh Ekstrak Daun Zaitun.
" We studied the importance of the smooth vascular muscle endothelium in vasodilator action of the decoction of olive (Olea europaea) leaf. We also showed that oleuropeoside is a component responsible for vasodilator activity but, from the results, it seems likely that at least one other principle is to be found in the olive leaf which is either a vasodilator itself or else potentiates the relaxant effect of oleuropeoside". Zarzuelo, et al., 417
" Plants in the Mediterranean basin, such as vine and olive trees, have developed an array of antioxidant defenses to protect themselves from environmental stress. Accordingly, the incidence of coronary heart disease and certain cancers is lower in the Mediterranean area, where olive oil is the dietary fat of choice. As opposed to other vegetable oils, extra virgin olive oil, which is obtained by physical pressure from a whole fruits, is rich in phenolic components that are responsible from particular stability of some olive oil phenolics, namely hydroxytyrosol and neutrophils respiratory bust, and hypochlorous acid.[The results] indicate that both compounds are potent scavengers of superoxide radicals: whenever demonstrated in vivo, these properties may partially explain the observed lower incidence of CHD and cancer associated with the Mediterranean diet". Visioli, et al.,60
" The Mediterranean diet, rich in fruit, vegetables, grain, and vegetable oil (mainly olive oil) is correlated with a lower incidence of coronary heart disease (CHD). Natural antioxidants contained in the Mediterranean diet might also play a role in the prevention of cardiovasular diseases, through inhibition of LDL oxidation. Oleuropein 10 (-5) M effectively inhibited CuSO4-induced LDL oxidation as assessed by various parameters. We demonstrate in this investigation that polyphenolic components of the Mediterranean diet interfere with biochemical events that are implicated in atherogenetic disease [types of cardiovascular disease], thus proposing a new link between the Mediterranean diet and prevention of CHD." Visioli, Galli, 1965
