本研究的作者研究了精炼椰子油 (CNO) 中不同浓度或比例的三种微量成分（α-生育酚、γ-谷维素和植物甾醇）的相互作用，其中富含中链饱和甘油三酯。通过rancimat方法和DPPH·清除能力测定测定单个和组合微量成分的抗氧化特性，并评估三种微量成分之间的相互作用类型。结果表明，它们的相互作用类型与具有不同链长和甘油三酯饱和度的其他油基不同。精制CNO中这三种次要成分的抗氧化相互作用主要是协同作用。抗氧化能力通常随着组合浓度的增加而增加，并且抗氧化相互作用的类型与其比例相关。
The present study's author investigated the interactions of three minor constituents (α-tocopherol, γ-oryzanol, and phytosterol) with different concentrations or proportions in refined coconut oil (CNO), which was full of medium-chain saturated triglycerides. Antioxidant properties of individual and combined minor constituents were determined through rancimat method and DPPH• scavenging capacity assay, and the interaction types among three minor constituents were evaluated. The results revealed that their interaction types were distinct from other oil bases with different chain lengths and saturation of triglycerides. Antioxidant interaction of these three minor constituents in refined CNO was mainly synergistic. The antioxidant capacities generally increased upon concentration of combinations, and the types of antioxidant interaction were related to their proportion.
