Abstract

ASSIRI and HASSANIEN, (1)1 Biochemistry Department, Faculty of Medicine, Umm Al-Qura University , Makkah,  Saudi Arabia evaluated cold pressed clove (Syzygium aromaticum) oil (CO) for its lipid classes, fatty acid profiles, and tocol contents as well as its antiradical and antimicrobial properties.

Background

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).

Methodology

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.

Results

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 [a stable free radical; scavenging of DPPH radical is the basis of the DPPH antioxidant assay] 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.

Conclusion

In consideration of potential utilization, detailed knowledge on the composition and functional properties of clove oil (CO) is of major importance.
