ABSTRACT Pomegranate is known for high concentration of antioxidant phenolics contained in its seeds, and peel, and is considered “healthy” due to its nutritional content and biological actions. The aim of this study was to determine the nutritional quality, volatile and phenolic antioxidants in the juice, peel and seeds of pomegranate from two different regions of Mexico. The pomegranate variety Wonderful of the 2016 cycle, obtained from the Coyame and Cuauhtémoc regions of the state of Chihuahua, Mexico, were used to characterize the total phenolic content, antioxidant activity, nutritional quality and volatile compounds. Significant differences were found in evaluated parameters between the two regions. Pomegranates from Coyame region, had high amounts of antioxidant, phenol, flavonoid, anthocyanin and mineral. On the other hand, pomegranates from the Cuauhtémoc region had high amounts of protein, organic elements, and volatile compounds (alcohols, esters and aldehydes). Within these groups, the most abundant compounds were hexanol, (Z)-3-hexen-1-ol, hexanal, 4-Terpineol, α-Terpineol, and 2-Ethyl-1-hexanol. In the peel, high concentration of color, phenols, flavonoids, and antioxidants were observed. The extract of pomegranate juice had 59% anthocyanin content. The seeds had the highest mineral content. These results provide relevant information about the chemical properties of the pomegranate.

墨西哥种植的石榴 (Punica granatum L.) 中抗氧化酚类物质、营养品质和挥发物的测定

摘要 石榴以其种子和果皮中含有的高浓度抗氧化酚类物质而闻名，并且由于其营养成分和生物作用被认为是“健康的”。本研究的目的是确定来自墨西哥两个不同地区的石榴汁、果皮和种子中的营养质量、挥发性和酚类抗氧化剂。来自墨西哥奇瓦瓦州 Coyame 和 Cuauhtémoc 地区的 2016 年石榴品种 Wonderful 用于表征总酚含量、抗氧化活性、营养质量和挥发性化合物。发现两个区域之间的评估参数存在显着差异。来自 Coyame 地区的石榴含有大量的抗氧化剂、苯酚、类黄酮、花青素和矿物质。另一方面，Cuauhtémoc 地区的石榴含有大量蛋白质、有机元素和挥发性化合物（醇类、酯类和醛类）。在这些组中，最丰富的化合物是己醇、(Z)-3-hexen-1-ol、己醛、4-萜品醇、α-萜品醇和 2-乙基-1-己醇。在果皮中，观察到高浓度的色素、酚类、类黄酮和抗氧化剂。石榴汁提取物中的花青素含量为59%。种子的矿物质含量最高。这些结果提供了有关石榴化学性质的相关信息。观察到高浓度的色素、酚类、类黄酮和抗氧化剂。石榴汁提取物中的花青素含量为59%。种子的矿物质含量最高。这些结果提供了有关石榴化学性质的相关信息。观察到高浓度的色素、酚类、类黄酮和抗氧化剂。石榴汁提取物中的花青素含量为59%。种子的矿物质含量最高。这些结果提供了有关石榴化学性质的相关信息。
