Bambara groundnut (Vigna subterranea) an indigenous legume proclaimed to have medicinal properties within rural areas. Therefore, this study aimed to identify possible medicinal properties of Bambara groundnut (BGN). Flavonoids and tannins were highly concentrated in the red and brown BGN hulls. Among the flavonoid compounds rutin was observed in highest concentrations in brown hull (24.458 ± 0.234 mg g−1) and myricetin (1.800 ± 0.771 mg g−1). While among tannin compounds chlorogenic acid was found in highest concentrations (0.115 ± 0.199 mg g−1) and ellagic acid in red hull (0.105 ± 0.082 mg g−1). The form and colour of the BGN were all important factors to optimize the best extraction yield of phytochemicals. Overall the hulls of the BGN were the optimum source of flavonoids and tannins.

南非Mpumalanga的Bambara花生(Vigna subterranea)的类黄酮和单宁组成
班巴拉花生(Vigna subterranea)是一种土著豆类,据说在农村地区具有药用价值。因此,本研究旨在确定Bambara花生(BGN)的可能药用特性。黄酮和单宁高度集中在红色和棕色的BGN船体中。在黄酮类化合物中,芦丁的最高浓度出现在棕色壳(24.458±0.234 mg g -1)和杨梅素(1.800±0.771 mg g -1)中。在单宁化合物中,绿原酸的浓度最高(0.115±0.199 mg g -1),鞣花酸在红皮中的浓度最高(0.105±0.082 mg g -1))。BGN的形式和颜色都是优化植物化学物质最佳提取得率的重要因素。总体而言,BGN的船体是类黄酮和单宁的最佳来源。
