Exploring the Chemical Composition of Olive Stems Essential Oil from Ethiopia

Key Findings:

  • The study identified 128 chemical compounds in the essential oil, constituting 89.4% of the total oil composition.
  • The major constituents include:
    • Methyl ester hexadecanoic acid (4.10%)
    • 2,4-Dimethoxyphenol (4.05%)
    • 2-Methoxy-phenol (3.25%)
    • 3,5-Dimethoxy-4-hydroxytoluene (3.20%)
    • 2-Methoxy-5-methyl phenol (3.19%)
    • 1,2,3-Trimethoxy-5-methyl benzene (2.93%)
    • 2-Methoxy-4-vinyl phenol (2.70%)
    • Trans-Isoeugenol (2.45%)
    • (E) -2,6-Dimethoxy-4-(prop-1-en-1-yl) phenol (2.25%)
  • The essential oil is rich in phenolic compounds (35.49%), which are known for their antibacterial, antifungal, antiviral, anti-inflammatory, and antioxidant activities.

Comparison with Other Studies:

  • The chemical profile of Ethiopian olive stems essential oil differs from similar studies in Algeria, Tunisia, and South Africa.
  • Factors such as plant age, harvesting time, geographical location, and extraction methods contribute to these variations.

Scientific and Medicinal Implications:

  • Phenolic compounds in the essential oil have shown strong antimicrobial properties, which could be useful in developing natural remedies.
  • The study highlights the potential of Ethiopian olive stems as a source of natural antioxidants, which are essential in combatting oxidative stress-related diseases.

Related Research & External Sources:

  • According to the American Botanical Council (ABC), plant-derived essential oils have been widely researched for their pharmacological properties and industrial applications.
  • More research on olive-based essential oils and their bioactive compounds can be found at the National Center for Biotechnology Information (NCBI).
