摘要
通过气相色谱法对牡丹籽油、核桃油、南瓜籽油、葡萄籽油四种特种植物油中的甾醇总量及组成进行分析研究。结果表明,牡丹籽油甾醇总量为240.0 mg/100 g,其主要组分是β-谷甾醇、Δ5,23-豆甾二烯醇和Δ5-燕麦甾烯醇;核桃油甾醇总量为100.5 mg/100 g,其主要组分是β-谷甾醇;南瓜籽油甾醇总量为299.6~358.4 mg/100 g,其主要组分是β-谷甾醇、Δ5,24-豆甾二烯醇和Δ7-燕麦甾烯醇;葡萄籽油甾醇总量为222.5~234.9 mg/100 g,其主要组分是β-谷甾醇、菜油(芸薹)甾醇和豆甾醇。分析结果为特种植物油的开发及加工提供了基础数据及技术支撑。
The total content of sterols in 4 kinds of special vegetable oils,i.e.peony see d oil,walnut oil, pumpkin seed oil and grape seed oil,and their composition were analyzed by gas chromatography.The result showed that sterols content in peony oil was 240.0 mg/100 g,of which the main components wereβ-sitosterol,Δ5 ,23-stigmastadienol and Δ5 -avenasterol;In walnut oil,the total content of sterols was 100.5 mg/100 g andβ-sitosterol was the main component;In pumpkin seed oil,the total content of sterols was 299.6~358.4 mg/100 g,and the main components wereβ-sitosterol,Δ5,24-stigmastadi-enol and Δ7-avenasterol;In grape seed oil,the total content of sterols was 222.5~234.9 mg/100 g, and the main components were β-sitosterol,campesterol sterol and stigmasterol.The research provides basic data for development and process of special vegetable oil.
