Background: Raw material standardization before preparation of any formulation is of prime importance. In this article we will deal with the Haridra (Curcuma longa Linn.) a well-known versatile drug used traditionally as well as routinely by mankind since long time. There are lots of researches available on its different therapeutic applications and standardization.

Aim: To standardize Haridra (Curcuma longa Linn.) by using parameters laid down by Ayurvedic Pharmacopoeia of India.

Material and Method: Dried Rhizome of Haridra was studied macroscopically and microscopically. Haridra powder was tested for physico-chemical characteristic like loss on drying, total ash, acid insoluble ash, water soluble extractive, alcohol soluble extractive, Phyto- constituent presence, Thin layer chromatography, FTIR, AAS and microbial contamination.

Result: The test results are comparable with the standard values given in Ayurvedic Pharamacopoeia of India and found within the prescribed range. FTIR revels the presence of amide group, AAS confirmed the heavy metal presence below permissible limit and absence of any microbial growth was determined by microbial study.
