Abstract

<smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="country-region"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"> A simple, rapid, and selective HPTLC method has been established for separation and determination of curcumin, extracted from rhizomes of different <i>Curcuma </i>species, which are sold in herbal drug markets of India by the name of <i>Amraharidra</i>. Chromatography was performed on silica gel 60F₂₅₄ plates with chloroform: ethanol: acetic acid, 95: 4: 5 (v/v), as mobile phase. Detection and quantification were performed densitometrically at <img src='/image/spc_char/lamda.gif'> _max = 260 nm with curcumin as external standard. This method was also found suitable for rapid screening of plant materials for chemotaxonomic. </smarttagtype></smarttagtype>
