A chemical study was conducted from 2009 to 2012 to examine spatial and seasonal variability of red Vitis vinifera Mencía located in different geographic areas (Amandi, Chantada, Quiroga-Bibei, Ribeiras do Sil and Ribeiras do Miño) from NW Spain. Mencía samples were analysed for phenolic, (flavan-3-ols, flavonols, anthocyanins, acids and resveratrol), nitrogen (TAC, TAN, YAN and TAS) and volatiles compounds (alcohols, C6 compounds, ethyl esters, terpenes, aldehydes, acids, lactones, volatile phenols and carbonyl compounds) by GC-MS and HPLC. Results showed that the composition of Mencía cultivar was more affected by the vintage than the geographic area. The amino acid composition was less affected by both geographic origin and vintage, showing more varietal stability. Application of Principal Component Analysis (PCA) to experimental data showed a good separation of Mencía grape according to geographical origin and vintages. PCA also showed high correlations between the ripening ratio and C6 compounds, resveratrol and carbonyl compounds.
2009年至2012年开展了一项化学研究，以考察西班牙西北部不同地理区域（阿曼迪、钱塔达、基罗加-比韦、锡尔河畔和米尼奥河畔）的红色酿酒葡萄门西亚的空间和季节变异性。采用气相色谱-质谱联用仪（GC-MS）和高效液相色谱仪（HPLC）对门西亚样本的酚类物质（黄烷-3-醇、黄酮醇、花青素、酸类和白藜芦醇）、氮（总酸度、总氮、酵母可同化氮和总可滴定酸）以及挥发性化合物（醇类、C6化合物、乙酯、萜烯类、醛类、酸类、内酯类、挥发性酚类和羰基化合物）进行了分析。结果表明，与地理区域相比，年份对门西亚品种成分的影响更大。氨基酸组成受地理来源和年份的影响较小，表现出更强的品种稳定性。对实验数据进行主成分分析（PCA）显示，根据地理来源和年份，门西亚葡萄得到了很好的区分。主成分分析还显示，成熟度比率与C6化合物、白藜芦醇和羰基化合物之间存在高度相关性。
