An attempt has been made to study the effect of different light intensities on the concentration of total proteins, amino acids, carbohydrates and total chlorophyll in different parts of Andrographis paniculata. Increase in concentration of total proteins, amino acids and carbohydrates was observed in the plants grown in higher light intensity (1.44×103 − 2.24×103 μmol m−2 s−1). The leaves of these plants showed increased amount of these metabolites compared to other parts. However, the total chlorophyll was found higher in the leaves of the plants grown in less light intensity (0.24×103–0.96×103 mol m−2 s−1). The results suggest that less light intensity hinders the production of total proteins, amino acids and total carbohydrates, while it has promoting effect on the synthesis of total chlorophyll.
