In the presence of oxygen, a crude soy extract converted 13-hydroperoxy-cis-9,trans-11-octadecadienoic acid into numerous products, from which 9-oxo-trans-12,13-epoxy-trans-10-octadecenoic acid was isolated. Additionally, the soy extract oxidized linoleic acid to the oxo-epoxyoctadecenoic acid, presumably via a sequential reaction involving lipoxygenase oxidation of linoleic acid followed by degradation of the resultant linoleic acid hydroperoxide. However, the linoleic acid substrate yielded two isomeric linoleic acid hydroperoxides and because of this, two isomeric oxoepoxyoctadecenoic acids.
在有氧存在的情况下，一种粗制大豆提取物将13-氢过氧-顺-9，反-11-十八碳二烯酸转化为多种产物，从中分离出了9-氧代-反-12,13-环氧-反-10-十八碳烯酸。此外，大豆提取物将亚油酸氧化为氧代环氧十八碳烯酸，推测是通过一系列反应，包括亚油酸的脂氧合酶氧化，随后是生成的亚油酸氢过氧化物的降解。然而，亚油酸底物产生了两种异构的亚油酸氢过氧化物，因此，也产生了两种异构的氧代环氧十八碳烯酸。
