Abstract
Citrus grandis or pomelo flowers possess a characteristic of strong blended of jasmine-and orage-like fragrance. In this study three different types of extraction techniques namely Solid Phase MicroExtraction SPME Soxhlet extraction and hydrodistillation technique were used to extract the fragrance compounds from the flowers. Determination of the fragrance constituents was done by gas chromatography-mass spectroscopy GC-MS. In the SPME method a fiber equipped with 65 m poly dimethylsiloxane-divinylbenzene was used and samples were permitted to achieve an equilibrium state for 20 minutes prior to fiber adsorption for 15 min at room temperature followed: . desorption time of 10 min. The analysis showed the presence of volatile compounds such as 3.89 of -myrcene 61.69 of limonene 13.89 of ocimene 5.76 of linalool and 1.53 of naphthalene as the major constituents. In the Soxhlet extraction method however the major compounds detected were limonene 9.41 ocimene 1.62 linalool 1.93 cyclohexasiloxane 1.17 and benzoic acid 2.92. From the hydrodistillation technique the major compounds found in blossom were linalool 15.93 benzoic acid 10.02 1 6 1 0-dodecatrien-3-ol 6.80 geraniol 6.43 :. furanmethanol 4.24 indole 4.03 and limonene 3.11 . This preliminary study shows that SPME offers better analytes extraction simplicity and rapidness and could be used directly without organic solvents.
