Study of the effect of Sodium dodecyl sulphate (SDS) on isolation of Curcumin from oleoresin of Turmeric (Curcuma longa)

This study was undertaken for extraction and isolation of Curcumin from Curcuma longa rhizomes. In the present study effect of sodium dodecyl sulphate on the isolation of Curcumin was carried out and it was found that it helps in the isolation of Curcumin from the oleoresin of Curcuma longa. The structure of the compound was elucidated and confirmed by thin layer chromatography, infrared spectroscopy, mass spectrometry and nuclear magnetic resonance spectral analysis. HPLC method was used for the identification and quantification of Curcumin by comparing with a standard.
