摘要
Mung bean (Vigna radiata L.) seeds (MBS) contain abundant nutrients with biological activities. This study was aimed to isolate key bioactive components from MBS with antioxidant and myocardial preservation activities. A new flavonoid C-glycoside, isovitexin-6 ''-O-alpha-L-glucoside, and 14 known compounds were obtained. Their structures were identified by extensive 1D and 2D NMR and FTICRMS spectroscopic analyses. The antioxidant activities of these compounds were evaluated. Compounds 15 and 710 displayed 2,2'-azinobis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS+)scavenging activity, but only 5 and 7 exhibited 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity. The myocardial preservation effect of 2, 3, and MBS were investigated by measuring the serum levels of LDH, CK, and AST as well as the tissue level of MDA and SOD. The results demonstrated that 2, 3, and MBS had a significant protective effect against ISO-induced myocardial ischemia. MBS can be regarded as a potential new source of antioxidants and myocardial preservation agents.
