It shows antioxidant activity, including protection against gamma-radiation in animal models. Studies in Drosophila melanogaster suggest potential anti-Parkinson effects as well as increased longevity.^[1]

Kolaflavanone (as part of the biflavonoid fraction kolaviron) has also been investigated for protective effects against reproductive toxicity. Findings from animal studies suggest amelioration of chemically or radiation-induced reproductive damage, although vitamin E has shown similar protective effects.^[2][3][4] In vitro studies indicate that kolaflavanone may protect neuronal cell lines from toxic insults induced by the herbicide atrazine, a known endocrine-disrupting chemical.^[5][6] Kolaflavanone has further been reported to exert antidiabetic effects in experimental models.^[7]

Extraction methods for biflavonoids from Garcinia kola nuts, including kolaflavanone, have been described in patent literature.^[8]
