ABSTRACT

Traditional medicine is the main source of medical care for a great percentage of the population of the developing world. Medicinal plants have been a valuable source of natural active phytoconstituents that play an important role in treatment of many human diseases. In the present study, stem (St), leaf (Lf), root (Rt), and flower (Fl) of Cleistanthus collinus (Roxb.) Benth. Ex Hook.f. was evaluated for its phytochemicals and antibacterial potential. The Soxhlet extraction was done by using three different solvents viz., acetone, methanol and water. Qualitative phytochemical analysis of the crude powder extracts of stem, leaf, root and flower was carried out for various phytoconstituents. The antimicrobial activity was evaluated by an agar disc diffusion method against four bacterial strain and two fungal strain. Qualitative phytochemical analysis shows presence of secondary metabolite in extracts. The methanol extracts showed better antimicrobial activity than acetone and aqueous extracts. This may be because of the difference in the presence of phytoconsituents present in
them.
