摘要：
A series of amino acids and carboxylic acids ere determined by C-13 NMR spectroscopy. The results showed that addition of 3M MgCl2, led to shortening of relaxation time and C-13 NMR integral area of samples was well proportional to the number of carbon atoms with reliability more than 95%. So MgCl2 is proposed as an efficient relaxation agent for analysis of amino acids and some carboxylic acids. (C) 2002 Elsevier Science (USA). All rights reserved.
