摘要: 为了明确山东、广东、河南3个地区花生品种VE、植物甾醇组成及含量的差异,采用高效液相色谱法对上述3个地区共45个花生品种中VE、植物甾醇的组成及含量进行分析测定。研究表明:3个地区花生品种中均含有α-、γ-、δ-VE 3种VE异构体和菜油甾醇、豆甾醇、β-谷甾醇3种植物甾醇。总VE含量排序为河南>广东>山东,α-VE含量排序为广东>河南>山东,γ-、δ-VE含量排序均为河南>山东>广东。总甾醇、菜油甾醇、豆甾醇、β-谷甾醇含量排序均为河南>山东>广东。同时,所有花生品种的3种VE异构体中均以α-VE含量最高,占总VE含量的70.37%~78.27%,3种植物甾醇中均以β-谷甾醇含量最高,占花生中植物甾醇总量的61.98%~71.65%。

Abstract: The tocopherol and phytosterol composition of 45 peanut cultivars from Shandong, Guangdong and Henan provinces was comparatively analyzed by HPLC. The results showed that three VE isomers (α-, γ-, and δ-VE) and three sterols (campsterol, stigmasterol and β-sitosterol) were found in each peanut cultivar. Three provinces were Henan, Guangdong and Shandong in the decreasing order of total VE content, Guangdong, Henan and Shandong in the decreasing order of α-VE content, Henan, Shandong and Guangdong in the decreasing order of γ- and δ-VE contents, and Henan, Shandong and Guangdong in the decreasing order of total sterol, campstreol, stigmasterol, and β-sitosterol contents. For each peanut cultivar, α-VE was the most predominant VE isomer, accounting for 70.37%–78.27% of the total VE amount, and β-sitosterol was most dominant among three sterols, representing 61.98%–71.65% of the total sterol amount.
