摘要
Background: White Velvet bean (Mucuna pruriens) is a very valuable plant due to its medical potential. Different parts of the plant have been studied by various researchers. However, the seeds, which contain a lot of bioactive compounds, have been considered of substantial medicinal importance. Methods: The total phenolic content, total flavonoid content, antioxidant and trypsin inhibition properties in the methanol extract of white Velvet bean (WVB) seeds and its fractions (methanol, n-hexane, ethyl acetate, n-butanol and aqueous) were studied. Result: The highest total phenolic content was recorded in the methanol extract (206.3 mg GAE g-1). The highest total flavonoid content was in the n-hexane fraction (7.75 mg rutin g-1). The methanol extract showed the highest total antioxidant potential (261.5 mg AAE g-1). The methanol extract also had the strongest DPPH radical scavenging activity and the highest level of trypsin inhibitory activity compared to the other fractions with an IC50 value (35.3 mu g mL-1).
