ABSTRACT
This study was done to investigate the yearly variation for phytochemical compounds in medicinal plant,
Justicia adhatoda L. Significant variations were witnessed among the flavonoids, whereas insignificant
variations were observed in alkaloids, saponins and tannins. Higher amount of flavonoid was observed
in the second year i. e. 2.7±0.67 mg/g and lesser amount of flavonoid content was observed during first
year viz., 1.7±1.88 mg/g. The study revealed that the plant’s phytochemical composition responded to
daily as well as seasonal environmental fluxes that happened throughout the year. The plant chemically
adapted itself according to the specific environmental conditions.
Key words : Justicia adhatoda L., yearly, variation, medicinal, plants
