Standardization of Siddha formulation Nilaavaarai Chooranam: A spectrophotometric fingerprint method

Nilaavaarai Chooranam is an important Siddha formulation, is official in formulary of Siddha Medicine. Quantification of active principles through modern analytical tools is essential for establishing the authenticity, creditability, prescription and usage of Traditional medicines/herbal formulations. Selective and efficient analytical methods are required not only for quality assurance but also for authentication of herbal formulations. The poly herbal formulations containing ginger are widely used for different medicinal properties. The present study is an attempt to develop the fingerprint method for Nilaavaarai Chooranam by spectrophotometric determination using 6-Gingerol as a standard, which is as an important content in formulation. The estimation was carried out with three laboratory batches and one marketed formulation by spectrophotometric approach at 282.5 nm. The UV spectrophotometric analysis is a simple, precise, and accurate method that can be considered as one of the quality control method for routine analysis.
