Recent research on carboxylic ester hydrolases was conducted by investigators at An-Najah National University, focusing on the essential oil derived from the dried leaves of Teucrium polium L., also known as felty germander or Palestinian Ja'adeh. The study aimed to investigate the chemical composition of the essential oil and evaluate its antioxidant, anticancer, a-amylase, and lipase inhibitory properties. The essential oil extracted from the dried leaves of T. polium L. via hydrodistillation was analyzed using gas chromatography-mass spectrometry (GC-MS), revealing 16 compounds, including E-nerolidol, geranyl acetone, and germacrene D, as the principal components.

Key Takeaways:

  • The essential oil extracted from the dried leaves of T. polium L. demonstrated notable antioxidant activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) at a concentration of 20.08 ± 1.00 g/mL.
  • The essential oil exhibited significant anticancer effectiveness against the MCF-7 and B16F10 cell lines, with IC50 values recorded at 30.56 g/mL and 32.75 g/mL, respectively.
  • The study found that the essential oil had restricted lipase activity and insufficient a-amylase activity.
  • The research suggests that T. polium L. essential oil is a potential source of natural antioxidants and has anticancer properties, making it a viable candidate for pharmaceutical and cosmetic use.

Statistics:

  • 16 compounds were identified in the essential oil of T. polium L., with E-nerolidol (27.11%), geranyl acetone (23.26%), germacrene D (19.08%), b-caryophyllene (17.78%), and a-caryophyllene (3.35%) constituting the principal components.
  • The essential oil demonstrated antioxidant activity at a concentration of 20.08 ± 1.00 g/mL.
  • The essential oil exhibited anticancer effectiveness against MCF-7 and B16F10 cell lines with IC50 values of 30.56 g/mL and 32.75 g/mL, respectively.
