Abstract

14 compounds were detected in the unsaponifiable matter of pea oil by gas liquid chromatography (GLC) and 8 of them were identified as hydrocarbons C30, C32, squalene, alpha-tocopherol, cholesterol, campesterol, stigmasterol and beta-sitosterol. The predominant unsaponifiable fraction was beta-sitosterol whereas the others were found in variable amounts. Two sterols were isolated by column chromatography. One of them was characterised as beta-sitosterol by measuring the melting point, [a]D, and infrared spectra and those of its acetate. However, the other sterol was unidentified. The fatty acid contents in pea oil were determined quantitatively by GLC. They were present in variable amounts, whereas linoleic acid was the major one.

摘要

通过气液色谱法（GLC）在豌豆油的不皂化物中检测到14种化合物，其中8种被鉴定为碳氢化合物C30、C32、角鲨烯、α-生育酚、胆固醇、菜油甾醇、豆甾醇和β-谷甾醇。主要的不皂化部分是β-谷甾醇，而其他成分含量各不相同。通过柱色谱法分离出两种甾醇。其中一种通过测量熔点、比旋光度、红外光谱及其醋酸酯的光谱被鉴定为β-谷甾醇。然而，另一种甾醇未被鉴定出来。通过GLC定量测定了豌豆油中的脂肪酸含量。它们的含量各不相同，其中亚油酸是主要的脂肪酸。
