摘要

Oleuropein is a polyphenol found in olive trees that has shown beneficial effects in animal studies and potentially in human health, although few studies have been performed to confirm this hypothesis in the latter population. Previous studies related its antioxidant activity to cardioprotective effects and showed a positive correlation between dose and response. We thus aimed to assess the cardioprotective effect of oleuropein and olive leaf extract in animal experiments. A literature search was conducted in June 2020 in the PubMed, Scopus and Web of Science databases. The descriptors “oleuropein” and “oleuropein aglycone” identified 12 articles for qualitative synthesis. Risk of bias was assessed by SYRCLE's RoB tool for animal studies. The results demonstrate evidence of a positive association between the administration of oleuropein and olive leaf extract and improvement in outcomes in hypertension, heart failure, myocardial infarction. renal hypertension and diabetes. This review presents a positive effect of oleuropein and olive leaf extract administration on cardiovascular parameters in animal studies. A oleuropeína é um polifenol encontrado nas oliveiras que tem efeitos benéficos em estudos com animais e potencialmente na saúde humana, embora poucos estudos tenham sido realizados para justificar essa hipótese. Em estudos prévios a atividade antioxidante foi relacionada aos efeitos cardioprotetores e mostraram uma correlação positiva entre a administração e a resposta. Portanto, o objetivo do estudo foi avaliar o efeito cardioprotetor da oleuropeína e da folha de oliveira em experimentação animal. A pesquisa preliminar foi realizada em junho de 2020 nas bases de dados Pubmed, Scopus e Web of Science. Os descritores oleuropein e oleuropein aglycone resultaram em 12 artigos para síntese qualitativa. O risco de viés foi avaliado pela ferramenta SYRCLE ROB adaptada para estudos em animais. Os resultados demonstram evidências de associação positiva entre a administração de oleuropeína e folha de oliveira em desfechos relacionados na melhoria da hipertensão arterial, insuficiência cardíaca, enfarte agudo do miocárdio, hipertensão renal e diabetes. Esta revisão apresenta uma associação positiva da administração de oleuropeína e folha de oliveira acerca dos parâmetros cardiovasculares em estudos com animais.
