Andrographis paniculata is one of the most important medicinally important plants grown worldwide. The plant is exploited for its medicinally important compound i.e. Andrographolide. But the impact of actual growth stages and proper light condition for extraction of the metabolite have not been worked out till date. The present investigation aims to study the effect of two different light conditions such as Sunlight and Shade and different growth stage i.e. Vegetative, Flowering and Fruiting on the physiology of the plant including the changes in enzymes i.e. Peroxidase (POX), Polyphenoloxidase (PPO), Succinate Dehydrogenase (SDH) and Aspartate Aminotransferase (AAT). The changes in the concentration of flavonoids and Andrographolide were also worked out. The study revealed a close relationship of metabolite concentrations with light and growth.
