I tried distilling vanilla beans (hydrodistillation) but did not get any oil after 4 hours. However, the hydrosol had the same odor of vanilla. Is there a way to get the vanilla oil? Thank you!
If you only want to analysis the chemical constituents of Vanila oil, you could partition hydrosol with cloroform or n-hexan. If you want to collect the oil, you could have sample extracted with ethanol 90%, after that you decrease the concentration of ethanol by means of adding water to the extract so that the oil maybe apart from the ethanol extract.
In general oils are non-polar compounds, so you have to extract with non-polar solvent, such as hexane or petroleum ether ( like -dissolves-like).Then separate the components using GC-MS and compare with standers.
Good Luck
