不同的生姜品种可能含有不同的营养和药用价值。本研究采用时域核磁共振技术对不同生姜品种的水分动力学进行了研究。河南姜与其他4个姜品种在植物不同部位水分分布的横向松弛时间2值上存在显著差异。离子浓度和代谢分析表明，不同生姜品种间Mn离子浓度和有机溶质含量差异相似。Pearson相关分析显示，nmrt2relax测定的多种有机溶质和生姜主要活性物质6-姜辣素与水分分布呈显著相关，表明有机溶质差异可能影响水分分布。我们的研究表明，低场核磁共振弛豫测量提供了不同生姜品种受不同有机溶质影响的水动力学的有用信息。
Different ginger cultivars may contain different nutritional and medicinal values. In this study, a time-domain nuclear magnetic resonance method was employed to study water dynamics in different ginger cultivars. Significant differences in transverse relaxation timeT2values assigned to the distribution of water in different parts of the plant were observed between Henan ginger and four other ginger cultivars. Ion concentration and metabolic analysis showed similar differences in Mn ion concentrations and organic solutes among the different ginger cultivars, respectively. On the basis of Pearson’s correlation analysis, many organic solutes and 6-gingerol, the main active substance of ginger, exhibited significant correlations with water distribution as determined by NMRT2relaxation, suggesting that the organic solute differences may impact water distribution. Our work demonstrates that low-field NMR relaxometry provides useful information about water dynamics in different ginger cultivars as affected by the presence of different organic solutes.
