In this study, scientists from Zimbabwe and Kazakhstan investigated how extracts from the fruits of Annona stenophylla and Flacourtia indica may help in the prevention of cancer caused by the formation of free radicals due to exposure to ultraviolet (UV) light. Their findings were published in the Journal of Medicinal Plants Research.

• For their analysis, the researchers obtained extracts containing phenolic compounds from A. stenophylla and F. indica fruits using aqueous methanol as solvent.
• They measured the ability of the extracts to scavenge free radicals, such as DPPH, and used ascorbic acid, a known antioxidant, as positive control.
• They also treated red blood cells (RBC) from sheep's blood with different concentrations of the extracts and assessed each extract's ability to inhibit hemolysis after exposure to UV radiation.
• The researchers found that, at low concentrations, the fruit extract from F. indica demonstrated lower antioxidant activity than ascorbic acid. However, at high concentrations, the F. Indica fruit extract performed better as a free radical scavenger than the control.
• Meanwhile, the researchers found no significant difference between the antioxidant potency of the A. stenophylla fruit extract and ascorbic acid. However, at the half maximal inhibitory concentration (IC₅₀), A. stenophylla fruit extract exhibited a higher antioxidant potency than the control.
• At higher concentrations, the F. indica extract was better at inhibiting hemolysis than ascorbic acid.
• There was no significant difference between the abilities of A. stenophylla fruit extract and ascorbic acid to inhibit hemolysis.

Based on their findings, the scientists concluded that extracts from the fruits of A. stenophylla and F. indica show promise as natural products that can be used to help prevent the onset of cancer.
