Turmeric (Curcuma longa L. Family: Zingiberaceae) is a widely cultivated spice in India and other Asian countries.
Curcumin is the main coloring substance in Curcuma longa and two related compounds, demethoxycurcumin and
bisdemethoxycurcumin are altogether known as curcuminoids. Turmeric is rich in curcuminoids, and recognized for
their broad spectrum of biological activities. During isolation and purification of curcuminoids from oleo resin, the
volatile oil present turmeric solubilizes curcumin creating problem in recrystallization process. To eliminate the
interference of volatile oil and resolve the problem recrystallization, the present research work was undertaken.
Various organic solvents and their combinations were tried for selective recrystallization of curcuminoids. Mixture of
hot isopropyl alcohol: hexane (1:1.5) was found to be the b.. View More»
