hi,
The oil can be extracted through steam distillation process. Turmeric leaf oil contains various bioactive compounds out of which Curcumin is the major constituent. Because of the reported presence of Monoterpene compounds to the tune of 26.6 to 30.9%, the oil can also be used as an active fumigant, repellents or insecticides for stored grain insects, for aromatherapy, for pharmaceutical use, for flavouring purposes etc. The recovery per cent is around 2 i.e. if 100 kg leaf is used, it produces 2 lit. oil only.
