摘要

In this study, profiles of lipid characterization and free radical scavenging capacity of Torreya grandis (T. grandis) kernel oils obtained from two varieties (T. grandis Fort. ex. Lindl. and T. grandis Fort. var. Merrillii) using three techniques (hot pressing, cold pressing and solvent extraction) were investigated and compared. The contents of the main fatty acids (linoleic, oleic, sciadonic and palmitic acids) in the T. grandis Fort. ex. Lindl. and T. grandis Fort. var. Merrillii kernel oils showed significant differences (P & 0.05). T. grandis Fort. ex. Lindl. kernel oils exhibited higher phytochemicals and free radical scavenging capacities. Meanwhile, hot pressed kernel oils presented much higher antioxidant abilities than the cold pressed and solvent extracted kernel oils, which were mainly correlated to the amounts of a-tocopherol, beta-tocopherol, beta-sitosterol and polyphenols. Chemometrics was employed in order to evaluating the certain contributions of the minor components to free radical scavenging capacity of the T. grandis kernel oils, as well as to indicating the differences and similarities of the T. grandis kernel oils.

Grandis Fort的主要脂肪酸(亚油,油,Sciadonic和棕榈酸)的含量。前任。 Lindl。和T. Grandis Fort。 var。 Merrillii内核油状差异显着(P&amp; <0.05)。 T. Grandis Fort。前任。 Lindl。籽粒油具有更高的植物化学和自由基清除能力。同时,热压籽粒油比冷压制和溶剂提取的籽油油呈现了更高的抗氧化能力,其主要与α-生育酚,β-生育酚,β-谷甾醇和多酚的量相关。采用化学计量学,以评估次要组件的某些贡献,以自由激进核心油的自由基清除能力,以及表明T. Grandis籽油油的差异和相似性。
