Phytochemistry
The essential oil obtained by steam distillation of dry rhizomes has been reported to contain α- phellandrene, d- sabinene, cineole, borneol, zingiberene and sesquiterpene ketones. In the recent analysis of the essential oil, tuemerone ar- turmerine and sabonone have been identified in the ketonic fraction besides p- cymene, isocaryophyllene, trans β-farnesene, δ- curcumene, β- bisabolene and β-sesquiphellandrene. Recent work on the study of sesquiterpenes has revealed a new compound curlone.The crystalline colouring matter curcurnin is deferuloyl methane.
