Antioxidant constituents such as carotenoids (capsanthin, phytoene, lutein, β-cryptoxanthin), polyphenols content (p-coumaric, ferulic, p-hydroxybenzoic, caffeic acid, sinapic acid, and quercetin-3-glucoside) and marketable yield were investigated in 11 sweet pepper cultivars grown under controlled temperature plastic tunnel and white shade net. Marketable yield was not affected by either of the environments, while the interaction between cultivar and growing environment significantly affected the accumulation of antioxidant constituents. The principal component analysis illustrated that controlled temperature plastic tunnel improved the accumulation of carotenoid components and ascorbic acid and vitamin C content in most cultivars. On the contrary, white shade nets favoured the accumulation of phenolic compounds and ORAC activity in most cultivars. A strong correlation was noted between phytoene and carotenoid components in this study (capsanthin r = 0.60; P < 0.001; lutein r = 0.75; P < 0.001; β-carotene r = 0.78; P < 0.001) while ORAC correlated with phenolic compounds. Based on this study, it is possible to refine the choice of environment and cultivar to enhance individual antioxidant constituent groups to improve health benefits for consumers.

抗氧化剂成分，如类胡萝卜素（辣椒红素，八氢番茄红素，叶黄素，β-隐黄质），多酚含量（对-香豆酸，阿魏酸，p-羟基苯甲酸，咖啡酸，芥子酸和槲皮素-3-葡萄糖苷）和11种甜椒品种的可销售产量进行了研究，这些品种在可控温度的塑料隧道和白色阴影网下生长。适销对路的产量不受任何环境的影响，而品种与生长环境之间的相互作用则显着影响抗氧化剂成分的积累。主成分分析表明，控制温度的塑料隧道改善了大多数品种中类胡萝卜素成分的积累以及抗坏血酸和维生素C的含量。相反，在大多数品种中，白色遮阳网有利于酚类化合物的积累和ORAC活性。很强的相关性在这项研究中番茄红素和类胡萝卜素成分之间的注意（辣椒红[R = 0.60; P  <0.001；叶黄素r  = 0.75; P  <0.001；β-胡萝卜素r  = 0.78; P  <0.001），而ORAC与酚类化合物相关。根据这项研究，有可能改善环境和品种的选择，以增强单个抗氧化剂成分，从而改善对消费者的健康益处。
