Method: By soxhlation process methanolic extract were prepared and use as indicator. The crude fresh juice is collected from Beta vulgaris, used as indicator in Spectro photometric titration. After few days of collecting crude juice also used as a natural indicator in Spectrophotometric titration. Result: Only the fresh crude juice of Beta vulgaris shows the sharp colour changes at the end point of titration.
