Condensed Tannin Content in Four Landraces of Bambara groundnut (Vigna subterreanea (L.) Verdc)

Abstract

Condensed tannins of four landraces grown in Botswana were determined using the acidified vanillin method  (Parca et al.l980). Botswana cream and Diphiri cream landraces had equal amount of tannin, 0.05 percent; while  Zimbabwe red and Botswana red had 0.10 percent. There was a significant difference (P < 0.05) between the tannin  content of the cream and red landraces. The quantity of tannin determined was low and might not adversely affect the digestion of proteins.
