In recent years, entomophagy has attracted increased attention, as it was recommended as a potential source of food by the Food and Agriculture Organization of the United Nations. In Japan,Oxya yezoensisis one of the most widely eaten insect species, but studies of its functionality as a food are limited. In this study, we reported the optimal characterization of the total phenolic compounds in methanolic extract (OME) and different fractions of OME. Additionally, the antioxidant and antiallergic activities of the OME fractions were evaluated. The results showed that the ethyl acetate-soluble fraction of OME has potential antioxidant activity, whereas the n-hexane-soluble fraction showed the strongest inhibition of β-hexosaminidase, which is one of the key factors in allergic reactions. It was concluded that phenolic compounds might contribute to the antioxidant activity while unsaturated fatty acids contribute to the antiallergy activity.

近年来，食虫引起了越来越多的关注，因为它被联合国粮食及农业组织推荐为潜在的食物来源。在日本，条獐虫是食用最广泛的昆虫物种之一，但对其作为食物的功能的研究有限。在这项研究中，我们报告了甲醇提取物 (OME) 和不同部分 OME 中总酚类化合物的最佳表征。此外，还评估了 OME 部分的抗氧化和抗过敏活性。结果表明，OME的乙酸乙酯可溶级分具有潜在的抗氧化活性，而Ñ -己烷可溶级分显示出最强的抑制β-氨基己糖苷酶，这是过敏反应的关键因素之一。结论是酚类化合物可能有助于抗氧化活性，而不饱和脂肪酸有助于抗过敏活性。
