Ginger, the rhizome of Zingiber officinale Roscoe, is a popular spice used in the food, beverage and confectionary industries. In this study, we report an untargeted UPLC-Q/TOF-MS-based metabolomics approach for comprehensively discriminating between ginger from two geographical locations, Ghana in West Africa and China. Forty batches of fresh ginger from both countries were discriminated using principal component analysis and orthogonal partial least squares discrimination analysis. Sixteen differential metabolites were identified between the gingers from the two geographical locations, six of which were identified as the marker compounds responsible for the discrimination. Our study highlights the essence and predictive power of metabolomics in detecting minute differences in same varieties of plants/plant samples based on the levels and composition of their metabolites.
姜,即姜科植物姜(Zingiber officinale Roscoe)的根茎,是一种在食品、饮料和糖果行业中广泛使用的香料。在本研究中,我们报告了一种基于超高效液相色谱-四极杆/飞行时间质谱联用(UPLC-Q/TOF-MS)的非靶向代谢组学方法,用于全面区分来自两个地理位置(西非的加纳和中国)的姜。使用主成分分析和正交偏最小二乘法判别分析对来自两国的40批新鲜姜进行了区分。在来自两个地理位置的姜之间鉴定出16种差异代谢物,其中6种被鉴定为导致区分的标志物化合物。我们的研究突出了代谢组学在基于植物/植物样品相同品种代谢物的水平和组成检测微小差异方面的本质和预测能力。
