Hexane and petroleum ether were used to extracting the scents from gardenia
flowers. Six treatments of 50, 60, 70, 80, 90 and 100 g flowers were soaked with 1 liter of each
solvent on 30 minutes. Removing the residue flowers and removing the solvent were done by
rotary evaporator to obtain concrete. Gardenia absolutes were separated from concrete by
alcohol. The optimum ratios between flowers and solvents were determined (Pensuk et al.,
2007).
The comparison of yield extracts from each methods of enfleurages and solvents
extraction were assessed. The saturated point of fat, oil and solvent in order to absorb the
scents from gardenia were determined. In addition physical appearances such as
characteristics, color and scent of all extracts were observed.
