Hi, for the voltile oil recovery from the distillat, u can use liquid-liquid extraction (solvent with low boiling point are preferred: diethyl ether, isopentane, pentane or a mixture...), the upper organic layer (enriched with volatile component) was recovered, concentrated under reduced pressure and then analyzed. Good luck
