Semi-arid regions are a source of several high nutritional plant species yet underexplored. The prickly pear cactus (Opuntia ficus-indica) provides a secure source of nutrients and antioxidants for human consumption. This study aimed to describe and assess the antioxidant capacity of prickly pear cladodes in different development stages. A completely randomized experimental design was used in a 2 × 4 factorial scheme with six replications: two cultivars (Gigante and Redonda) and four development stages (1 – cladodes of 4.0 to 8.0 cm; 2 – 8.01 to 12.0 cm; 3 – 12.01 to 16.0; and 4 – 16.01 to 20.0 cm). Diameter, fresh mass, and yield increased significantly according to the cladode stages, especially in the Redonda cultivar, while protein, lipid, and carbohydrate contents decreased with advanced stages on both cultivars. The highest chlorophylls, carotenoids, and flavonoid contents were obtained at the third and fourth stages in the Gigante cultivar. The highest total phenols were obtained at the first and second stages also in the Gigante cultivar. Ascorbic acid content increased according to the stages in both cultivars, and antioxidant capacity was higher in dry mass when compared to fresh mass. Prickly pears cladodes are suitable for the human diet at any stage of development. However, due to the concentrations of compounds with antioxidant properties, the third and fourth stages are recommended for fresh consumption.

不同发育阶段仙人掌分枝的描述和抗氧化能力

半干旱地区是几种高营养植物物种的来源,但尚未得到充分开发。仙人掌仙人掌 ( Opuntia ficus-indica) 为人类消费提供了安全的营养和抗氧化剂来源。本研究旨在描述和评估仙人掌分枝在不同发育阶段的抗氧化能力。完全随机的实验设计用于 2 × 4 析因方案,重复 6 次:两个品种(Gigante 和 Redonda)和四个发育阶段(1 - 4.0 至 8.0 cm 的分支;2 - 8.01 至 12.0 cm;3 - 12.01 至16.0;和 4 – 16.01 至 20.0 厘米)。直径、鲜质量和产量根据分支阶段显着增加,特别是在 Redonda 品种中,而蛋白质、脂质和碳水化合物含量随着两个品种的晚期阶段而下降。在 Gigante 品种的第三和第四阶段获得了最高的叶绿素、类胡萝卜素和类黄酮含量。在 Gigante 品种的第一和第二阶段也获得了最高的总酚。抗坏血酸含量根据两个品种的阶段而增加,与新鲜物质相比,干物质的抗氧化能力更高。刺梨分枝适合任何发育阶段的人类饮食。然而,由于具有抗氧化特性的化合物的浓度,建议在新鲜食用第三和第四阶段。
