【资料】NMR develops a nose for wine(用NMR研究葡萄酒)

上载一些NMR研究葡萄酒的资料,有兴趣者可以看看,NMR如何研究食品和复杂混合物.实际上,只要能溶解的样品,都可以用液体NMR来研究,并不是一定要纯化合物才用NMR,本人日常相当一部分工作是分析混合物的NMR图谱,深感NMR的功能强大.
Wine analysis by 1D and 2D NMR spectroscopy
Analusis 26, 97-101 (1998)
Abstract
We have measured 1D and 2D 1H and 13C NMR spectra of selected Slovenian wines. Partial assignment of 1H and 13C resonances of alanine, valine, leucine, isoleucine, proline, threonine, ethanol, glycerol, butyleneglycol, and of acetic, tartaric, lactic, succinic, and malic acids in the wine samples was carried out by the combination of homo- and heteronuclear experiments COSY, HSQC and HMBC with known spectra of individual compounds. The spectra of wines of different variety, vintage and geographical areas differ mainly in the intensity of particular signals but also in the appearance of some signals which offers the possibility to follow the variability in their chemical composition on the ground of 1H and 13C signals.
