EXTRACTION OF CURCUMIN FROM TURMERIC ROOTS

The title of this artical is entitled as “Curcumin Extraction from Turmeric Roots”. It is a research project taken from indo NACOP CHEMICALS ltd., a herbal and natural colour manufacturing company. It is situated at Vinukonda, AP, India.
Turmeric, curcuma longa L of Zingiberaceae family 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 curcuminoid Turmeric is rich in curcuminoids, and recognized for their broad spectrum of biological activities, curcuminoids vary in chemical structures, physico-chemical characteristics as well as the functional properties.
Curcumin extracted from turmeric (Curcuma longa L.,Zingaberaceae) root was found to be anti-angiogenic in a human tissue-based angiogenesis. As a liposoluble compound, curcumin can be extracted from turmeric root with organic solvents such as ethanol or acetone. Curcumin in its pure form has poor solubility in water, potentially limiting its medicinal use for humans when it is taken orally or injected. Experiments were undertaken to determine the extraction weight of different solvents for curcumin and optimum parameters and best solvent which gives high yield.
