The red grape Vitis vinífera is an important source of phenolic compounds, which can prevent disease if included as a part of a diet. The levels of these compounds in grapes have been associated with various environmental factors, such as climate, soil composition, and biotic stress. The purpose of this study was to determine the relationship between the elemental compositions of the soil and the grapes and the presence of bioactive compounds, such as catechin, epicatechin, piceid and resveratrol. Ethanol-based extracts of red grapes were used to quantify total and individual phenolic compounds by HPLC. It was observed that the elemental compositions of the soil and the grapes were related to their locations within different wine-producing regions. A principal component analysis showed a relationship between high metal content (Sr, Mn, Si and Pb) and higher concentrations of antioxidants in the grapes.
红葡萄(Vitis vinífera)是酚类化合物的重要来源，如果将其作为饮食的一部分，这些化合物可以预防疾病。葡萄中这些化合物的水平与各种环境因素有关，如气候、土壤成分和生物胁迫。本研究的目的是确定土壤和葡萄中的元素组成与生物活性化合物（如儿茶素、表儿茶素、白藜芦醇苷和白藜芦醇）的存在之间的关系。使用基于乙醇的红葡萄提取物通过 HPLC 定量测定总酚和单体酚化合物。观察到土壤和葡萄的元素组成与其在不同葡萄酒产区的位置有关。主成分分析表明，高金属含量（Sr、Mn、Si 和 Pb）与葡萄中抗氧化剂浓度较高之间存在关系。
