Abstract Share this page

In order to assess the kinetics of extraction Citrus aurantium leaves underwent hydrodistillation with a Clevenger apparatus. Essential oil was collected every 15 minutes during the whole extraction period. Yield variation during extraction period revealed an exponential aspect curve with 95% of maximum yield at 150 minutes. Sixty one compounds were identified during extraction time. Chromatographic analysis showed notable differences between the different p etitgrain samples especially for the major components: linalool (29.74 - 62.43%), α - terpineol (3.04 - 15.69%) and linalyl acetate (5.64 - 25.38%). Important variations were observed in petitgrain chemical composition according to extraction time and each compone nt presented a specific kinetic according to extraction time. These variations may be the expression of variable chemical and physical phenomena that take place in Clevenger hydrodistillation batch
