                                                               Medicinal Properties 

Antioxidant Activity In the Taiwanese study, the antioxidant activity in mature fruits of 36 species and varieties produced in Taiwan was analyzed by the ferric reducing antioxidant power . In this study, sugar apple was categorized as having very high antioxidant activity i.e >70mmol/100g edible part. Many studies including conducted in India showed that extracts of Annona squamosa, Annona cherimola and Annona muricata have high antioxidant activity.

Effects on Cardio-Vascular Disease

fresh custard apple fruit potently lowered plasma triglyceride concentrations by 65% of mice fed a moderately high fat diet for four weeks and exhibited a potent inhibitory effect on adipogenesis reducing fat tissue by about 20%. This anti dyslipidemic action is significant in prevention of cardiovascular morbidity

Anti HIV properties

Among the 14 isolated compounds in a study, -dihydroxy-entkauran-19-oic acid showed significant activity against HIV replication in H9 lymphocyte cells with an EC50 value of 0.8 μg/m

Antidiabetic properties :

Studies in rabbit showed that 5 g of semi-dried pulp of sugar apple per kg of body weight was effective as a supplement in anti-diabetic treatment. This amounts to eating one eighth of normal custard apple in humans. The probable mechanism may be due to increased sensitivity to insulin

leaf extracts are also effective in lowering blood glucose levels and several reports indicates that Annona squamosa leaf extract can substitute effectively with decreased doses of externally administered insulin

Anticancer properties :

Tumor cells have three distinguishing properties like they have a transport mechanism to transport glucose faster into them, they develop new blood vessels called neoangiogenesis, thereby getting more nutrients diverting from normal cells and they also have a MDR (multi drug resistance) protein expression which throws out a drug from the cell saving them from the killing actions of the anticancer drugs.

The anti-cancer properties of custard apple appear to be mainly due to a class of compounds called acetogenins which are specific to Annonaceaous species. Acetogenins have been tested in vitro against 60 types of cancer cells, including breast, prostate and colon.

Anti-infective :

The fruit of Annona spp. have been shown to have anti-microbial activities due to several compounds which include Ent-kauranes, Acetogenins, essential oils and Benzylisoquinolines alkaloids. The anti-bacterial activity of the crude methanol extract of sugar apple and an isolated diterpene, against Staphylococcus aureus and Streptococcus pneumonia is being established. There are also reports of chemicals which are also active against Candida albicans, proteus
