o:3065 Olive oil and olive leaf extracts consumption: A survey on consumer’s attitudes en Olive oil is the basis of the Mediterranean diet, which is considered one of the best diets in terms of preventing modern-day diseases (high blood pressure, increased triglycerides, cholesterol, obesity and diabetes). Olive oil consists primarily of triacylglycerols and about 0.5%-1.0% nonglyceridic constituents (Pierfrancesco et al., 2021; Kelli et al, 2002) but it is also a valuable source of different phenolic compounds (Rodríguez-López et al, 2021). Many of phenolic compounds contribute to the resistance of olive oil to oxidative rancidity and is also beneficial for human health (Rodríguez-López et al, 2021; Suvarna and Sharma., 2021). Numerous reports have shown that olive oil phenols are potent inhibitors of LDL oxidation in vitro (Visioli et al., 1995) and it is known that the oxidation of LDL is linked to the formation of atherosclerotic plaques (Visioli et al., 1995). In human randomized controlled trials, olive oils rich in phenolic compounds have shown to protect against oxidative damage and inflammation and to improve the quantity of cholesterol transported by high-density lipoprotein and also the lipoprotein quality (Torre et al., 2021). The olive leaves are also rich source of bioactive compounds such as oleuropein, verbascoside, apigenin, luteolin and the triterpenoids i.e., oleanolic and maslinic acids (Nenadis et al., 2021). Regarding bioactivities, effects related to cardiovascular and respiratory diseases, cancers or diabetes are pointed for olive leaf extracts (Nenadis et al., 2021; Manna et al., 1997). 1552101 1857 - 8969 1552099 10.33320/maced.pharm.bull.2022.68.04.077 2023-10-19T09:43:34.536Z 44 no 46 Jelena Purić Farmeceutski fakultet, Univerzitet Privredna akademija Nov Sad 46 Dubravka Bigović Institut za proučavanje lekovitog bilja "Dr Josif Pančić" 0000-0003-1999-2743 46 Katarina Šavikin Institut za proučavanje lekovitog bilja "Dr Josif Pančić" 0000-0002-2086-9593 46 Jelena Živković Institut za proučavanje lekovitog bilja "Dr Josif Pančić" 0000-0002-9684-2637 46 Milan Ilić Farmeceutski fakultet, Univerzitet Privredna akademija Nov Sad application/pdf 221357 https://unilib.phaidrabg.rs/o:3065 no yes 1 70 1552253 71A10 Macedonian pharmaceutical bulletin 68 169 170 2022
