In recent years the use of natural antioxidants in foodstuffs and personal care products has become increasingly important for consumers and therefore manufacturers. In this work, sporopollenin exine capsules (SpECs), extracted from spores of the common club moss Lycopodium clavatum L, have been shown to protect an ω-3 oil from oxidation caused by natural light or accelerated oxidation with UV irradiation. The mechanism of action has been shown to be principally by free radical quenching as opposed to light shielding, supported by evidence of similarity in levels of protection when the ratio of SpECs to oil was 0.2 % w/v compared with 50 % w/w. The antioxidant effect is not materially altered by the extraction process from the raw material and is clearly an inherent property of the sporopollenin contained in the spores of L. clavatum due to the accessible phenolic groups on the surface on the SpECs. These results provide promising evidence that SpECs could be useful as a bio-sourced antioxidant for protecting ω-3 oils and related oxidation-prone molecules.

近年来，在食品和个人护理产品中使用天然抗氧化剂对消费者以及制造商而言变得越来越重要。在这项工作中，孢粉外壁胶囊（规格），从共用石松的孢子提取伸筋草已经证明L 1可以保护ω-3油免受自然光引起的氧化或紫外线辐射加速的氧化。已经显示出作用机理主要是通过自由基猝灭而不是光屏蔽，并且当SpEC与油的比例为0.2％w / v（50％w / w）时，保护水平的相似性也证明了这一点。抗氧化效果不是实质性由所述提取过程中从原料改变，显然包含在孢子的孢粉素的固有属性L. clavatum由于在规范的表面上的可访问的酚基。这些结果提供了有希望的证据，表明SpECs可用作生物来源的抗氧化剂，用于保护ω-3油和相关的易氧化分子。
