摘要:

绿豆(Vigna radiata)是重要的经济作物之一,具有抗氧化、抗炎和抗菌作用.然而迄今为止,绿豆代谢物组成信息仍不完善.为了系统地定量研究绿豆代谢物组成,该研究利用DOSY,J-RES,COSY,TOCSY,HSQC,HMBC 和1D 1H NMR 谱图在鄂绿4 号(ElüNo.4)绿豆水相提取物中鉴定和归属了48 种代谢物,确定了绿豆中棉籽糖家族寡糖的构成,并且利用全弛豫谱对其中44 种代谢物进行了定量分析.

Abstract:

Mungbean (Vigna radiata) is an important crop that has various beneficial functions such as antioxidant and anti-inflammatory activities. However, the metabolites in mungbean have only been partially identified and quantified in previous studies. In this study, we systematically identified and assigned 48 metabolites in mungbean (Elü No.4) seeds with J-RES, COSY, TOCSY, HSQC, HMBC and 2D NMR spectra. In particular, the composition of raffinose family oligosaccharides in the extracts was determined using DOSY experiments. Most of the metabolites in the extracts were quantified. This study will provide useful information for mungbean metabolomic and nutritional studies.

Key words: nuclear magnetic resonance, assignment, 2D NMR, mungbean, quantification
