A spectrophotometric method for determination of total lactones in Andrographis paniculata was established by using dinitrobenzoic acid and potassium hydroxide solutions as colour forming agents. The absorbance of the solution was determined at 536 nm. The linearity range was 12-72 × × × × × 10 -6 g.ml -1 . The detection limit was 1.2 µ µ µ µ µg, the quantitation limit was 4.23 µ µ µ µ µg. The intraday variation had an average of slope 6082.97 g.m
