The factor(s) responsible for the unexplained atherogenicity of peanut oil remain to be elucidated. To this end, we developed a technique to determine if lectin was present in the oil and to quantitate its concentration. This technique was applied to other vegetable oils including corn, soybean, and sunflower. Crude, unprocessed corn and soybean oils were also analyzed for lectin content. The crude oils contained from 858 to 2983 micrograms lectin per kg, while the refined oils contained 24 to 55 micrograms/kg of biologically active lectin. The identities of the isolated lectins were confirmed by electrophoresis on SDS-polyacrylamide gels. The biological significance of the presence of lectin in these oils remains to be determined.
花生油产生无法解释的致动脉粥样化作用的因素仍有待阐明。为此，我们开发了一种技术来确定油中是否存在凝集素并对其浓度进行定量。该技术应用于其他植物油，包括玉米油、大豆油和向日葵油。还对未加工的粗制玉米油和大豆油的凝集素含量进行了分析。粗制油中每千克含有858至2983微克凝集素，而精炼油中每千克含有24至55微克具有生物活性的凝集素。通过在SDS-聚丙烯酰胺凝胶上进行电泳确认了分离出的凝集素的身份。这些油中存在凝集素的生物学意义仍有待确定。
