Comparison of Essential Oils of Clove Buds Extracted Using Soxhlet and Ultrasonic-Assisted Extraction Methods (SHORT COMMUNICATION)

Cloves ( are the aromatic dried flower buds of a tree in the family Myrtacae. Clove's essential oil is widely used as aromatherapy and for toothache treatment. Development of extraction technology that could increase oil yield from clove would thus significantly enhance the profitability of the clove's oil and reduce processing costs significantly. In this research work an essential oil was obtained from using Sohxlet and an ultrasonic-assisted extraction methods with n-hexane as extraction solvent. The oil extract was analyzed for its chemical composition using gas chromatography/mass spectrometric (GC-MS). The results of analysis show that the essential oil yield were found to be 54.70% and 71.55% while the eugenyl acetate in extracts obtained were found to be 5.72% and 9.24% for sohxlet and ultrasonic-assisted extraction methods respectively.
