Annonas are economically important in many countries of Africa and Asia as well as
in South, North and Central America. In general, the annonas are shrubs or small
trees, with height from 5.0 to 7.5 m; they are erect or somewhat spreading and possess
grey-brown bark, oft
en rough and corrugated. Th
ey also serve as sources of medicinal
and industrial products. Annona fruits provide good carbohydrate nutrition, acting as
excellent sources of energy. Th
ey are important sources of minerals, such as calcium,
phosphorus and potassium. Th
ese are important in biological functions, such as
helping to protect bones and teeth, providing strong muscles and improving general
health. Annona plant parts used in folk medicine contain chemical compounds such
as tannins, alkaloids and fl
avonoids found in the roots, leaves, bark, fruits and seeds.
Acetogenins, for instance, are present in the seeds, roots, bark, stems and fruits of
most annona trees, and appear to have great potential in anti-cancer treatments and
as anti cholesterol . Cherimoya roots have aporphine alkaloids, which have a relaxant
Cholesterol is known to involve oxidative stress and changes in lipid metabolism.
Cholesterol induced by triton WR 1339 injection at a dose of 0.20 mg/kg. Animals of
treated groups were given the dose of 0.50 mg/kg of the extract. An improvement of
antioxidant enzymes was associated with improved body weight control and healthier
les and therefore may play an important role in the anti obesity and
ects. Many secondary plant metabolites have been shown to possess
antioxidant activities, improving the eff
ects of oxidative stress due to cholesterol.
Our study has analysed that the antioxidant eff
ect of oral administration of methanol
leaf on antioxidant enzymes and lipid peroxidation in
blood-Triton WR 1339 induced rat.
