Abstract

An aqueous extract was obtained from the biomass of Hermetia illucens larvae using the electro-pulse plasma-dynamic method. The extract was highly effective in quenching the chemiluminescence of luminol in the presence of hemoglobin and hydrogen peroxide. It contained the dark pigment melanin with a concentration of paramagnetic centers of 8.3 × 10¹⁶ spin/g of dry matter and antioxidant activity. The antiradical properties of the extract were confirmed on the model of oxidative stress of the nematode Caenorhabditis elegans in the presence of 40 mmol of paraquat: the introduction of the extract increased the median lifespan of the nematode by 25%. The antioxidant effect identified is associated with the presence of a complex of antioxidants in the extract and, possibly, antioxidant enzymes that destroy hydroperoxides.

Hermetia illucens幼虫提取物的抗氧化特性

摘要

使用电脉冲等离子体动力学方法从Hermetia illucens幼虫的生物量中获得水提取物。在存在血红蛋白和过氧化氢的情况下，提取物在猝灭鲁米诺的化学发光方面非常有效。它包含深色颜料黑色素，其顺磁性中心浓度为8.3×10 ¹⁶ spin / g干物质和抗氧化活性。在线虫秀丽隐杆线虫的氧化应激模型上证实了提取物的抗自由基性能。在40 mmol百草枯存在的情况下：引入提取物可使线虫的中位寿命延长25％。确定的抗氧化作用与提取物中存在抗氧化剂复合物有关，并且可能与破坏氢过氧化物的抗氧化酶有关。
