Screening of wild plant species for antibacterial activity and phytochemical analysis of L.

Eight wild plant species namely L., (Roxb.)Benth. Ex Hook.f., L., (L.) Dc., (L.) R.Br. ex wight., Wight., Koern. and L. were used for phytochemical extraction with four different solvents. Antibacterial activity of these plants was studied against NCIM 2065 using Kirby Bauer agar disc diffusion assay. Effective antibacterial activity was shown by acetone extract (27.3 mm), compared to standard medicinal drug amoxicillin (28.3 mm). Minimum inhibitory concentration (MIC) of extract was 15 mg/mL and hence, it could be pursued further for obtaining phytomedicine. Biochemical constituents of fresh leaf were: sugars (55 mg/g), starch (0.7182 mg/g), proteins (0.0166 mg/g) and lipids (170 mg/g). Alkaloids, tannins, phenolic compounds, flavonoids and steroids were also observed qualitatively.
