The main objective of this investigation was to evaluate fruits of C. chinense accessions for their concentration of beta -carotene, ascorbic acid, and phenols for use as parents in breeding for these phytochemicals. Mature fruits of 63 accessions of C. chinense originally acquired from Belize, Brazil, Colombia, Ecuador, Mexico, Peru, Puerto Rico, and the United States were analyzed for their chemical composition. Fruits of C. chinense accessions PI-152452 (Brazil) and PI-360726 (Ecuador) contained the greatest concentrations of ascorbic acid (1.2 and 1.1 mg g(-1) fresh fruit, respectively), while PI-438648 (Mexico) contained the greatest concentration of total phenols content (349 micro g g(-1) fresh fruit) among the other 63 accessions tested. Accession PI-355817 from Ecuador contained the greatest concentrations of beta -carotene (8 mg g(-1)fresh fruit). These accessions were identified as potential candidates for mass production of antioxidants with health-promoting properties.
本研究的主要目的是评估中国枳属（C. chinense）不同品种果实中β-胡萝卜素、抗坏血酸和酚类物质的含量，以便将其作为亲本用于具有这些植物化学物质的杂交育种。对原产于伯利兹、巴西、哥伦比亚、厄瓜多尔、墨西哥、秘鲁、波多黎各和美国的 63 个中国枳属品种的成熟果实进行了化学成分分析。PI-152452（巴西）和 PI-360726（厄瓜多尔）品种的果实中抗坏血酸含量最高（分别为 1.2 和 1.1mg g-1 鲜果），而在其他 63 个品种中，PI-438648（墨西哥）品种的总酚含量最高（349μg g-1 鲜果）。来自厄瓜多尔的 PI-355817 品种的果实β-胡萝卜素含量最高（8mg g-1 鲜果）。这些品种被鉴定为具有促进健康的抗氧化剂大规模生产的潜在候选品种。
