【 摘 要 】

The aim of this work was to study the effect of dynamic maceration factors upon the curcumin content of Curcuma longa L., Zingiberaceae, extracts and to determine the optimum set of parameters for the extraction of curcumin using a 25 full factorial design and the response surface methodology. Under the established conditions, the content of soluble solids and curcumin in the extracts ranged from 0.8 to 3.4%, and from 0.1 to 1.8%, respectively. The most influential variable observed for the extraction was the ethanolic strength of the solvent. The optimized condition involves an extraction time of 12 h, agitation speed of 30 rpm, drug to solvent ratio of 1/6, extraction temperature of 80 ºC and the solvent with ethanolic strength of 70%. The data reported herein are useful for further developments of curcuma phytopharmaceutical intermediate products with optimized characteristics.
