Health promoting cold pressed oils may improve human health and prevent certain diseases. It is hard to find any research concerning the composition and functional properties of cold pressed clove (Syzygium aromaticum) oil (CO). Cold pressed CO was evaluated for its lipid classes, fatty acid profiles, and tocol contents. In addition, antiradical and antimicrobial properties of CO were evaluated. The amounts of neutral lipids in CO was the highest (∼94.7% of total lipids), followed by glycolipids and phospholipids. The main fatty acids in CO were linoleic and oleic, which comprise together ∼80% of total fatty acids. Stearic and palmitic acids were the main saturated fatty acids. α- and γ-tocopherols and δ-tocotrienol were the main detected tocols. CO had higher antiradical action against DPPH• and galvinoxyl radicals than virgin olive oil. The results of antimicrobial properties revealed that CO inhibited the growth of all tested microorganisms. CO had a drastic effect on the biosynthesis of proteins and lipids in cells of Bacillus subtilis. In consideration of potential utilization, detailed knowledge on the composition and functional properties of CO is of major importance.
具有促进健康作用的冷榨油可能改善人类健康并预防某些疾病。目前很难找到有关丁香（Syzygium aromaticum）油（CO）的组成和功能特性的研究。本研究对冷榨 CO 的脂质组成、脂肪酸谱和生育酚含量进行了评估。此外，还评估了 CO 的抗自由基和抗菌性能。CO 中的中性脂质含量最高（约占总脂质的 94.7%），其次是甘油脂和磷脂。CO 中的主要脂肪酸为亚油酸和油酸，共占总脂肪酸的约 80%。硬脂酸和棕榈酸是主要的饱和脂肪酸。α-和 γ-生育酚以及 δ-生育三烯醇是主要检测到的生育酚。CO 对 DPPH•和戊二醛自由基的清除能力强于特级初榨橄榄油。抗菌性能的结果表明，CO 抑制了所有测试微生物的生长。CO 对枯草芽孢杆菌细胞的蛋白质和脂质生物合成有显著影响。考虑到潜在的利用，CO 的组成和功能特性的详细知识非常重要。
