Abstract

Defatted kernel powder of mango (Mangifera indica) and wild mango (Irvingia gabonensis and Irvingia wombolu) were analysed for their in-vitro antioxidant activity and cytotoxicity. Dry matter content of the three kernel types were in the range of 93 to 95%. On defatting, the percentage oil yield of the Irvingia varieties were similar and 200% higher than that of Mangifera indica. The antioxidant activity using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) technique showed that the two Irvingia varieties (DIGK and DIWK) had similar IC50 (p>0.05) but significantly higher than that of Mangifera indica kernel (DMIK) (p<0.05). Likewise, results from the Ferric Reducing Antioxidant Power (FRAP) technique and Cytotoxicity assay confirmed the higher potency of DMIK over the Irvingia kernels.

Highlights

Conventional mango (Mangifera indica) is a tropical fruit-bearing plants which flourishes better in Africa and Asia
Another plant growing in wild tropical forests of family Irvingiaceae, is popularly called wild mango (Irvingia), African mango, bush mango, dika or ogbono
The oil yield of 22% from Mangifera indica kernel in this study was similar to that reported by Arogba (2015) as the variety was obtained from the same locality

Summary

INTRODUCTION

Conventional mango (Mangifera indica) is a tropical fruit-bearing plants which flourishes better in Africa and Asia. The kernel possesses relatively high phenolic content with effective antioxidant activity It contains tocopherols and stigmasterol (Bandyopadhyay et al, 2014). Residual levels of phenolic compounds could serve as antioxidants (Arogba, 2015) Another plant growing in wild tropical forests of family Irvingiaceae, is popularly called wild mango (Irvingia), African mango, bush mango, dika or ogbono. Methanolic extracts of Irvingia gabonensis kernel are used in the treatment of fungal and bacterial infections, similar to some other medicinal plants. Their kernel powder have culinary significance as soup-thickener (Matsinkou et al, 2012; Arogba, 2014).
