The profile of sterols and squalene content in oils recovered from the kernels of 15 apricot (Prunus armeniaca L.) varieties were investigated. Nine sterols (campesterol, β-sitosterol, Δ5-avenasterol, 24-methylene-cycloartanol, cholesterol, gramisterol, Δ7-stigmasterol, Δ7-avenasterol and citrostadienol) were identified in apricot kernel oils. The β-sitosterol was the predominant sterol in each cultivar and consisted of 76-86% of the total detected sterols. The content of total sterols and squalene were significantly affected by the variety and ranged between 215.7-973.6 and 12.6-43.9 mg/100 g of oil, respectively.
对15个杏（Prunus armeniaca L.）品种的果仁中提取的油类中的甾醇和角鲨烯含量概况进行了研究。在杏仁油中鉴定出9种甾醇（菜油甾醇、β-谷甾醇、Δ5-燕麦甾醇、24-亚甲基环阿屯醇、胆固醇、豆甾醇、Δ7-豆甾烯醇、Δ7-燕麦甾醇和柠檬甾二烯醇）。β-谷甾醇是每个品种中的主要甾醇，占检测到的总甾醇的76-86%。总甾醇和角鲨烯的含量受品种的显著影响，分别在215.7-973.6和12.6-43.9毫克/100克油之间。
