Evaluation of Turmeric (Curcuma longa Linn.) and its Extracts from Indian Market

Abstract

Curcumin is proving to be a potential drug molecule due to its multifarious activities and its freedom from toxicity [2,3]. Number of studies on designing of various formulations of curcumin are underway [4]. These formulations employ either pure curcumins or standardized extracts. The curcumins in the extracts and powders are analyzed employing different methods such as HPLC, Spectrophotometric [5] and HPTLC [6,7] methods. The present study was undertaken to evaluate different powder samples and extracts of turmeric available in the market along with the extracts prepared in our laboratory by employing spectrophotometric methods.
