Intensification of the Extraction Yield of Eucalyptus globulus Phenolic Compounds with Pulsed Electric Field

Eucalyptus extract-based pharmaceutical products are widely used because of their medicinal properties and rich content secondary metabolites, mainly phenolic compounds. This study aimed to maximise the extraction yield these compounds reduce duration by using a pulsed electric field (PEF) level 6 kV/cm. The pulse width (T), number pulses (n), solvent concentration [C] were analysed. Several ethanolic extracts obtained from leaves globulus, total phenols, flavonoids, condensed tannins was measured through spectrophotometry. results, immediately after PEF treatment, revealed that for optimal values analysed factors, phenol doubled flavonoid increased significantly. However, pre-treatment had no effect on tannin yield. Moreover, optimisation performed design experiments methodology identifying factors.
