Abstract

Opuntia monacantha is known in Brazil and is commonly marketed in some regions, as in the ecological fairs of Porto Alegre. This study aims to investigate the physical and mineral characteristics as well as antioxidant activity, antibacterial activity, and chemical profile of the main metabolites of the fruit extracts. The fruits are a source of fiber (pulp and peel: 7.01 mg, 9.01 mg/100 g), respectively, selenium pulp and peel (0.04 mg/100 g and 0.05 mg/100 g), copper pulp (1.05 mg/100 g) and manganese peel (67,83 mg/100 g). The pulp showed phenolic content related to an antioxidant potential attributed to quercetin and rutin constitution in the extracts. The antibacterial activity was observed against S. aureus ATCC 33591 (methicillin-resistant, MRSA) and ATCC 29213 (methicillin-sensitive, MSSA) at 512 µg.mL⁻¹ in the apolar extracts of the fruits constituted by saturated and unsaturated fatty acids, as well as phytosterols. The fruits presented a rich nutritional composition correlated with antioxidant and antibacterial action, being potential for health improvement and it can be explored by the food industry as well as in nature consumption by the population.

巴西 RJ 省 Grumari 沙洲的 Opuntia monacantha (Willd.) Haw.：物理、化学、生物和营养成分特征

Opuntia monacantha 在巴西家喻户晓，在某些地区，如阿雷格里港的生态博览会上，这种植物通常会在市场上销售。本研究旨在调查水果提取物的物理和矿物质特征、抗氧化活性、抗菌活性以及主要代谢产物的化学成分。水果是纤维（果肉和果皮：分别为 7.01 毫克和 9.01 毫克/100 克）、硒（果肉和果皮：分别为 0.04 毫克/100 克和 0.05 毫克/100 克）、铜（果肉：1.05 毫克/100 克）和锰（果皮：67.83 毫克/100 克）的来源。果肉中的酚含量与抗氧化潜力有关，这归功于提取物中的槲皮素和芦丁成分。由饱和脂肪酸和不饱和脂肪酸以及植物甾醇组成的果实萃取物对金黄色葡萄球菌 ATCC 33591（耐甲氧西林，MRSA）和 ATCC 29213（甲氧西林敏感，MSSA）的抗菌活性为 512 µg.mL-1。这些水果含有丰富的营养成分，具有抗氧化和抗菌作用，具有改善健康的潜力，可用于食品工业和人们的自然消费。
