Carotenoids are natural pigments and antioxidants found in fruits and vegetables such as carrot, tomato, orange, mango, yellow corn, pumpkin, and mamey. In this study, we evaluated the antioxidant potential of mamey () carotenoids and compared them to carrot () carotenoids. The carotenoids were extracted from mamey and carrot, and their antioxidant capacity were determined via (ABTS method) and assays (resistance against oxidative stress in ). The carotenoid contents in mamey and carrot were 4.42 ± 0.12 and 5.47 ± 0.04 mg β-carotene/100 g, respectively. Despite the differences between the carotenoid contents in both products (p < 0.05), the antioxidant capacity results showed no significant differences between the extracts (p > 0.05). The mamey and carrot carotenoid extracts decreased the oxidative damage in by 20-30% and 30-40%, respectively. Both extracts increased the resistance and enhanced the survival of the nematodes, and showed better effects than pure β-carotene, probably owing to the complex mixture in the carotenoid extracts. These results suggest that mamey is a good alternative source of carotenoids and that it protects against oxidative stress in . The protective effect of mamey carotenoids was similar to the effect of carrot carotenoids.
类胡萝卜素是存在于胡萝卜、番茄、橙子、芒果、黄玉米、南瓜和番荔枝等水果和蔬菜中的天然色素和抗氧化剂。在本研究中，我们评估了番荔枝类胡萝卜素的抗氧化潜力，并将其与胡萝卜类胡萝卜素进行比较。从番荔枝和胡萝卜中提取类胡萝卜素，并通过ABTS法和秀丽隐杆线虫抗氧化应激试验测定其抗氧化能力。番荔枝和胡萝卜中的类胡萝卜素含量分别为4.42±0.12和5.47±0.04毫克β-胡萝卜素/100克。尽管两种产品的类胡萝卜素含量存在差异（p<0.05），但抗氧化能力结果显示提取物之间无显著差异（p>0.05）。番荔枝和胡萝卜类胡萝卜素提取物分别使秀丽隐杆线虫的氧化损伤降低了20%-30%和30%-40%。两种提取物均提高了线虫的抵抗力并增强了其存活率，且比纯β-胡萝卜素显示出更好的效果，这可能归因于类胡萝卜素提取物中的复杂混合物。这些结果表明，番荔枝是类胡萝卜素的良好替代来源，并且它能保护秀丽隐杆线虫免受氧化应激。番荔枝类胡萝卜素的保护作用与胡萝卜类胡萝卜素的作用相似。
