Detection and estimation of curcumba longa in ayurvedic preparations

Methods were evolved for the detection of Curcuma longa in ayurvedic preparations. A simple method was also found out for the estimation of Curcuma longa in Vachalasunyadhi Taila using the formula -a = b/.32. Where a is the actual weight of Curcuma longa in Vilupatra Tailam and b is the weight obtained from graph of concentration of Curcuma longa VS OD. The methods evolved are so simple that it does not require any sophisticated instruments and hence it can be carried out in any quality control lab.
