Here we report on the occurrence of mycosporine-like amino acids (MAAs) in the Argentine shortfin squid, Illex argentinus, the second fishery resource mostly exploited in the Argentinean continental shelf. The total content of four MAAs was evaluated by reverse-phase-HPLC in different tissues (eyes, skin, liver, and gonads). Also, the antioxidant activity of crude extracts was assessed by in-vitro determinations: 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH), Folin-Ciocalteu, and ferrous ion-chelating capacity assays. The content of MAAs was found to be almost ten times higher in female gonads than in other tissues (11,89 ± 0,56 mg/g dry weight). Extracts from skin, female gonads and eyes, exhibit higher antioxidant activity than the reference compounds ascorbic acid and TROLOX. Overall, Argentine squid waste is a promising potential source of MAAs with antioxidant and UV photoprotective properties, which could bear interest in food, cosmetic and pharmaceutical industries, thus encouraging maximal and sustainable use of fishing resources.
我们在此报告在阿根廷短鳍鱿鱼（Illex argentinus）中存在类菌孢素氨基酸（MAAs），这是在阿根廷大陆架上开发的第二大渔业资源。通过反相高效液相色谱法（RP-HPLC）在不同组织（眼睛、皮肤、肝脏和性腺）中评估了四种 MAAs 的总含量。此外，通过体外测定评估了粗提取物的抗氧化活性：2,2'-偶氮双（3-乙基苯并噻唑啉-6-磺酸）（ABTS）、2,2-二苯基-1-苦基肼（DPPH）、福林-希考尔（Folin-Ciocalteu）和亚铁离子螯合能力测定。发现 MAAs 的含量在雌性性腺中几乎比其他组织高十倍（11,89±0,56 mg/g 干重）。皮肤、雌性性腺和眼睛的提取物比参考化合物抗坏血酸和 TROLOX 具有更高的抗氧化活性。总的来说，阿根廷鱿鱼废弃物是一种具有抗氧化和 UV 光保护特性的 MAAs 的有前途的潜在来源，这可能在食品、化妆品和制药行业中具有吸引力，从而鼓励对渔业资源的最大和可持续利用。
