Abstract
Background: There is much investigation with the Andrographis paniculata which is a very well-known medicinal plant, people were using this plant from ancient years, but this another species Andrographis echioides was not explored too much for many years. In this study we tried to find out the important phyto constitiuents, antibacterial activity and anti-inflammatory activity of this plant.
 Aim: The main aim of the present study, was to screen phytochemical derivatives from an Indian medicinal plant Andrographis echioides (L) Nees and to evaluate the antibacterial potential, and anti-inflammatory activity also.
 Study Design: Various tests or experiment was done in this study according to the review of the literature with little modification, a preliminary phytochemical screening was carried out in the plant extracts using qualitative methods. The whole plant of Anrographis echioides was subjected to soxhlet extraction using organic solvent of methanol, acetone, and petroleum ether. The antibacterial activity of acetone, methanol and petroleum ether whole plant extracts of Andrographis echioides was carried out using agar well diffusion method, anti-inflammatory activity was checked using fresh egg albumin method, and a statistical analysis was done using SPSS to prove that there is a strong correlation between the activity of our plant sample and a standard commercial drug (NASID).
 Place and Duration of the Study: The whole study was done in Panskura Banamali College, Vidyasagar University, Department of Biotechnology sponsored by BOOST, Louis Pasteur laboratory, West Bengal, India. The study was done between 17th August 2018 - 30th February 2019. 
 Results: All these tests were done triplicate and the mean value was taken. The phytochemical analysis reveals that the plant has some important phytoconstituents such as Tannins, flavonoids, phenolic compounds, glycosides and terpenoids. The Acetone and Methanol extracts are showed the best zone of inhibition against the severe pathogens such as S. aureus (A.E-33 mm, M.E-28 mm), S. typhi (A.E- 26.67 mm, M.E-28.33 mm). The methanolic extract of Andrographis echioides showed excellent anti-inflammatory activity comparing to the NASID (Non-steroidal anti-inflammatory drugs) Diclofenac sodium, it showed almost same activity.
 Conclusion: Experimental findings reveal Andrographis echioides is the best herbal to control specially S. typhi, E. coli, S. aureus, K. pneumoniae. The phytochemical constituents which are responsible for many pharmacological activities, may be useful for the evolution of pharmaceutical and for the therapy of ailments, and also can used as a an potent anti-inflammatory natural remedy without any side effect.
