A simple, rapid, accurate, precise and economic spectrophotometric method was developed for determination of p-coumaric acid in Cynodon dactylon Linn. In this method p-Coumaric acid shows absorbance maximum at different wavelength in different solvents, so absorbance was measured and the same wavelengths used for the estimation of p-Coumaric acid in respective solvents. p-Coumaric acid obeys the beer lamberts’ law. Method was validated according to ICH guideline and carried out for analysis of p-Coumaric acid.
