The color of pummelo fruit is an important trait, but specific pigments' contribution remains unclear. This study analyzed seven colored pummelo cultivars, including three red (Sanhongmiyou, Gusangyou, and Chuhongyou); three pale-red (Ruby pummelo, Guanximiyou, and Feihongyou) and one orange (Jinjumiyou). Carotenoid, flavonoid, and anthocyanin content and antioxidant capacity were analyzed for each cultivar. In the red and pale-red cultivars, narirutin and lycopene were the most abundant carotenoids and flavonoids, respectively, while β-carotene was the most abundant carotenoids in the orange cultivar. Anthocyanins were also detected in the three red cultivars, with the most abundant anthocyanin being cyanidin. Of the three red cultivars, Chuhongyou contained the highest levels of cyanidin (19.6 μg·g) compared to Sanhongmiyou (5.8 μg·g) and Gusangyou (2.8 μg·g. Polymethoxylated flavones, lycopene, and cyanidin-3-O-(6"-O-coumaryl)-galactoside were significantly correlated with antioxidant capacity. This study summarizes the pigment composition and antioxidant capacity in fruit flesh across a spectrum of pigmented pummelos.
柚子果实的颜色是一个重要性状，但特定色素的贡献仍不明确。本研究分析了7个有色柚子品种，包括3个红色品种（三红蜜柚、古桑柚和楚红柚）；3个浅红色品种（红肉蜜柚、琯溪蜜柚和飞红柚）和1个橙色品种（金桔蜜柚）。分析了每个品种的类胡萝卜素、黄酮类化合物和花青素含量以及抗氧化能力。在红色和浅红色品种中，柚皮芸香苷和番茄红素分别是含量最丰富的类胡萝卜素和黄酮类化合物，而β-胡萝卜素是橙色品种中含量最丰富的类胡萝卜素。在3个红色品种中也检测到了花青素，含量最丰富的花青素是矢车菊素。在3个红色品种中，楚红柚的矢车菊素含量最高（19.6μg·g），而三红蜜柚为（5.8μg·g），古桑柚为（2.8μg·g）。多甲氧基黄酮、番茄红素和矢车菊素-3-O-（6”-O-香豆酰基）-半乳糖苷与抗氧化能力显著相关。本研究总结了一系列有色柚子果肉中的色素组成和抗氧化能力。
