Another popular ethnomedicine Andrographis paniculata is used for the treatment of high blood pressure, ulcer, bronchitis, dysentery, malaria and different skin diseases. Phytochemical investigation on ethanolic leaf and stem extracts prove the presence of different important chemicals in these two medicinal plants. Thin layer chromatography also indicates the presence of multiple compounds in these two medicinal plants. Phytochemical and thin layer chromatographic investigation confirmed that chemical composition of leaf and stem extracts of the two samples are different.
