Overview

Randomized trial compares solar hydro-distillation efficiency in extracting essential oils and antioxidants from Pelargonium graveolens, suggesting a sustainable method for bioactive recovery.

Key Points

  • This study aims to compare the efficiency of solar hydro-distillation (SHD) to traditional methods for extracting essential oils and antioxidants from Pelargonium graveolens.
  • Utilized solar hydro-distillation to extract essential oils and evaluate antioxidant compounds.
  • Analyzed volatile components using GC-MS and quantified total phenolic and flavonoid content.
  • Assessed anti-cyanobacterial and anti-algal activity against specific strains.
  • SHD yielded essential oils at 0.64% compared to 0.60% from conventional hydro-distillation.
  • Identified main essential oil components included citronellol (27.54%), geraniol (11.94%), with significant antioxidant activity (IC50=6.54 μg/mL).
  • The extract showed strong anti-cyanobacterial and anti-algal activity with inhibition diameters of 15.43 mm and 25.96 mm respectively.
