方法:采用主成分分析和偏最小二乘法对600 MHz核磁谱仪测定的30批市售狗脊饮片1H-NMR谱图进行模式分析,揭示市售不同质地狗脊饮片内在成分上的差异。结果:狗脊饮片的质地与其多种成分含量密切相关。不同质地狗脊饮片成分差异主要表现为糖类、酚酸类、甾醇类及蕨素类成分的含量差异。狗脊饮片1H-NMR谱芳香区的酚酸...
1H NMR spectroscopic analysis coupled with multivariate statistical data was used to characterize wines vinified from four grape varieties: Muscat Bailey A (Vitis labrusca), Campbell Early (V. labrusca B.), Kyoho (V. labrusca L.) and Meoru (Vitis coignetiae). Pattern recognition methods, such...
1 H NMR spectroscopic analysis of tea leaves To understand the global metabolic dynamics in tea leaves as tea (C. sinensis) plants become aged, representative 1H NMR spectra of tea leaves collected from 8-year-old (a) and 25-year-old (b) tea plants plucked in May 2015 and April 2016...

Buffer for NMR analysis Phosphate buffer NaPi was prepared in H2O:D2O (1:1) to a final concentration of 1.5 M, pH 7.4. TSP-d4 and NaN3 (5 and 15 mM final concentration, respectively) were added to the buffer solution as internal chemical shift reference (TSP-d4) and for antibacte...
6Li and (13)C NMR spectroscopic studies were carried out on [(6)Li]n-BuLi and [(6)Li]PhLi (RLi) in toluene-d(8) containing the following diamines: N,N,N',N... JL Rutherford,D Hoffmann,DB Collum - 《Journal of the American Chemical Society》 被引量: 138发表: 2002年 Quantitati...
The 1H NMR spectroscopic analysis of the plant extract revealed the presence of acyclic aliphatic and 伪- mono substituted aliphatic group of compounds in the sample. Thus, it is apparent from the present study that methanol crude extract of E. agallocha is rich in aliphatic group of compounds ...
