Bio-flavonoids and garcinoic acid from garcinia kola seeds with promising anti-inflammatory potentials

Abstract

Objective: The research was carried out to investigate the anti-inflammatory effect of ethanol extract, fraction (kolaviron) and compounds (garcinoic acid, GB1 and GB2) of Garcinia kola seeds. Materials and Method: To evaluate the acute anti-inflammatory effect of extract, fraction and compounds of G. kola carrageenan-induced edema model in wistar albino rats was used. Results: Kolaviron (50 mg/kg), garcinoic acid (50 mg/kg) and the crude extract (50 mg/kg) caused 100, 83 and 74% inhibition of carrageenan-induced paw edema respectively at 6 h post administration. Indomethacin (10 mg/kg), the reference drug induced 100% inhibition of carrageenan-induced paw oedema. While GB1 (50 mg/kg) and GB2 (50 mg/kg) was prominent at 4, 5 and 6 h post administration. Conclusion: Results showed that the extract possessed anti-inflammatory activity, which have justified their use in Nigeria traditional medicine to treat inflammation.
