Antihypertensive, antiatherosclerotic and antioxidant activity of triterpenoids isolated from Olea europaea, subspecies africana leaves

Renal Effects of Plant-Derived Oleanolic Acid in Streptozotocin-Induced Diabetic Rats

“…[19] In conclusion, the results of the present study introduce the first in vivo evidence that oleanolic acid extracted from S. cordatum leaves ameliorates kidney function in STZinduced diabetic rats. The possible mechanisms behind the OA-evoked amelioration of kidney function are yet to be studied.…”

“…The crude ethyl acetate extract was subjected to further purification, as previous studies indicated that EAS contained bioactive compounds. [6,19] …”

Oleuropein using as an Additive for Feed and Products used for Humans

“…More recent knowledge of the olive leaf's medicinal properties dates back to the early 1800s when pulverised leaves were used in a drink to lower fevers. A few decades later, green olive leaves were used in tea as a treatment for malaria [15]. Numerous scientific studies have been added to investigate the extract's beneficial properties, and olive leaf extracts are suggested as dietetic products and/or food integrators [14].…”

“…Numerous scientific studies have been added to investigate the extract's beneficial properties, and olive leaf extracts are suggested as dietetic products and/or food integrators [14]. Olea europaea preparations have been started to use widely in folk medicine in European Mediterranean area, Arabia peninsula,India and other tropical and subtropical regions, as diuretic, hypotensive, emollient and for urinary and bladder infections [15].…”

Composition chimique et activités antibactériennes, antifongiques et antioxydante de l'huile essentielle dePelargonium asperumEhrh.exWilde des Comores

“…Selon Seyed & Fayed (2009) et Slater (1984, la protection antioxydante contre les dommages dus aux peroxydes dans les mécanismes du système immunitaire joue un rôle crucial dans la prévention ou/et la progression de certaines pathologies chroniques. En effet, les radicaux libres provoquent des stress responsables de plusieurs maladies telles que le diabète, le cancer, l'artériosclé-rose, les maladies cardiovasculaires et les désordres neurodégénératifs (Slater, 1984 ;vuillaume, 1987 ;Halliwell, 1987 ;Matsuda et al, 1996 ;Meydani, 1998 ;Kris-Etherton et al, 2002 ;Somava et al, 2003). Ainsi, de nombreux chercheurs se sont penchés sur l'activité antioxydante des huiles essentielles d'une grande variété de plantes aromatiques (Halliwell, 1987 ;Burke et al, 1997 ;Weiss, 1997 ;Yi et al, 2008).…”
