6. Increased antioxidant activity and polyphenol metabolites in methyl jasmonate treated mung bean (Vigna radiata) sprouts
Abstract Mung bean sprouts are a popular health food both in China and worldwide. We determined the optimal concentration of exogenous methyl jasmonate (MeJA) for the promotion of the sprouting in mung beans (Vigna radiata). The 1,1-diphenyl-2- picrylhydrazyl radical (DPPH) scavenging test showed that MeJA application resulted in significantly improved antio
