Description This work reports variations in the yields and quality of volatiles produced from
Eucalyptus citriodora leaves by different hydrodistillation (HD) and supercritical
carbon dioxide extraction (SCE) techniques. HD techniques (1.5%) produced
higher yields compared to SCE (0.7%). Citronellal, the major component, was
maximum in the extract produced by SCE (79%) followed by oil produced by
water–steam distillation (WSD) (72.6%) and water distillation (WD) (62.4%)
techniques. Chemical composition of glycoside-bound volatiles produced by acid
hydrolysis during HD was found to be very different from free volatiles, although
in a minor quantity. The extent of artefact formation and release of aglycones was
more profound in the bound volatile oil produced by WD than WSD. Highest
oxygenated monoterpenes were found in SCE and WSD (93% each) followed by
WD (91.4%). Although the SCE produced lower yields than the HD techniques,
its extract is superior in quality in terms of higher concentration of citronellal.
