2. Anti-inflammatory activities
In the
assessment of ethanolic extract of Carica papaya leaves and its anti-inflammatory activity effect found that the extracts significantly reduced the persistent oedema from the 4th day to the 10th day of the investigation.

anti-hyperlipidemic effect of the ether- and water-soluble fractions of C. papaya ethanol extract found that The study dose-dependently inhibited the total cholesterol (TC), triglycerides (TG), low-density lipoproteins (LDL) level, and significantly increased high-density lipoprotein (HDL) level. Phytochemical screening revealed the presence of fats in the ether fraction, whereas the water fraction revealed the presence of tannins, alkaloids, glycosides. UV ?(max) was found to be 217?nm with a melting point of 41?C for the isolated component, according to "Effect of ether- and water-soluble fractions of Carica papaya ethanol extract in experimentally induced hyperlipidemia in rats" by Iyer D, Sharma BK, Patil UK.(III)

Cellular oxidative stress
In the investigation of the papaya epicarp extract against hydrogen peroxide (H(2)O(2))-induced oxidative stress in human SH-SY5Y neuronal cells found that Papaya epicarp extract ameliorated glutathione depletion, restored total antioxidant capacity and augmented the inhibition of antioxidant enzymes (catalase, glutathione peroxidases and superoxide dismutase). In conclusion, papaya epicarp extract can be used as a functional dietary ingredient that might help in reducing the neurological health problems associated with various oxidative stress insults, according to "Papaya epicarp extract protects against hydrogen peroxide-induced oxidative stress in human SH-SY5Y neuronal cells" by Guizani N, Waly MI, Ali A, Al-Saidi G, Singh V, Bhatt N, Rahman MS.(IV)

Acute gastric damage and blood oxidative stress
In the determination of Carica papaya leaf (CPL) aqueous extract and its effect on alcohol induced acute gastric damage and the immediate blood oxidative stress level, found that CPL extract offered some protection with reduction in plasma lipid peroxidation level and increased erythrocyte glutathione peroxidase activity. Carica papaya leaf may potentially serve as a good therapeutic agent for protection against gastric ulcer and oxidative stress, according to "Protective effect of Carica papaya L leaf extract against alcohol induced acute gastric damage and blood oxidative stress in rats" by Indran M, Mahmood AA, Kuppusamy UR.(V)
