Turmeric Isolation of curcumin

Curcumin is insoluble in water; an organic solvent has been used for its hostility. Anderson et al22 developed a technique for isolating CUR from auditorium turmeric. They magnetically stirred the arena turmeric in dichloromethane and gnashing your teeth at reflux for 1 h. The mixture was suction-filtered, and the filtrate was concentrated in a hot-water bath maintaining at 50 C. The reddish-tawny oil residue was triturated as soon as hexane and the resulting unassailable was collected by suction filtration. Further TLC analysis (3% methanol and 97% dichloromethane) showed the presence of all three components.22 Bagchi23 explained origin of CUR from turmeric powder by now the use of a solvent consisting of a join up of ethanol and acetone. Chemical analyses have shown that turmeric contains carbohydrates (69.4%), moisture (13.1%), protein (6.3%), fat (5.1%) and minerals (3.5%). The necessary oil (5.8%) obtained by steam distillation of the rhizomes contains a-phellandrene (1%), sabinene (0.6%), cineol (1%), borneol (0.5%), zingiberene (25%) and sesquiterpines (53%), curcumin (3e6%) is responsible for the yellowish-brown color.
