Rhodino as mixture of citronellol and geraniol has been isolated from the trade citronella oil.; geraniol from rhodino was changed to be come pseudoionone (_-ionone). The first step was done to chice the tide citronella oil that using GC and GC-MS to know the content of rhodinol from each trade citronella oil. Then was done the isolation of rhodinol from citronella oil by using fragtional destillation with diminishing pressure. Pseudoionone (_-ionone) was obtained via the reaction of geranil (from rhodinol) with aluminium isopropoxide with aceton, whereas the citronellal not react. The reaction was done along 10 hours with methode of reflux with temperature 75°C. The product that obtained was done the fragtionaly destillation with dimiss pressure. The yield that obtained was yellow liquid and was analysed by using GC-MS. The content of rhodinol that isolated from trade citronella oil was 68.86%. the reaction between the geraiol from the rhodinol and aluminium isopropoxide and aceton yielded the 16.94% cis-pseudoionone and the 30.34% trans pseudoionone.
