STUDY ON PRELIMINARY PHYTOCHEMICAL AND ANTIBACTERIAL ACTIVITY AGAINST HUMAN PATHOGENS OF AN ENDANGERED ORCHID-HABENARIA PLANTAGINEA LINDL
AbstractHabenaria plantaginea Lindl. (Orchidaceae) is used as a medicinal plant in several countries. In this study, ethanol, chloroform and water extracts of Habenaria plantaginea were evaluated for antibacterial activity against bacterial (MTCC) strains. Antibacterial activity of this plants extracts were performed using agar disc diffusion method. The antibacterial activity of ethanol extracts showed more effective followed by water and chloroform extracts against all the bacterial strains. Preliminary phytochemical studies were performed for the presence and absence of secondary metabolites in the whole plant. The Minimum Inhibitory concentration (MIC) exhibited by H. plantaginea extract against the bacterial strains ranged between 0.125 mg/ml to 6 mg/ml. The presence of bioactive constituents is associated with the antimicrobial activity of various solvent extracts of this plant was carried in attempt to support the use by medicinal practitioner for the treatment of various diseases. Medicinal importance of this orchid will target to meet the therapeutic demands
