Abstract :

Current investigation is aimed to assess seven different endangered plants (Curcuma zedoaria, Cayratia pedata, Utleria salicifolia, Syzygium travancorium, Nothapodytes nimmoniana, Rhaphidophora persuta, Plectranthus vettiveroides) in terms of their phytochemical assessment and antimicrobial activity against different pathogens such as Escherichia coli, Staphylococcus aureus, Streptococcus mutans, Salmonella typhi, Klebsiella pneumonia, Bacillus cereus and Pseudomonas aeruginosa. Phytochemical analysis showed the variation in presence of bioactive compounds in the leaf, stem and root extracts of different plants. The leaf extract of Rhaphidophora persuta showed six positive test among the ten corroborating the extract as an potential origin of herbal medicine. Different parts the plants such as stem, roots and leaves exhibited antimicrobial activity against pathogens which was determined by observing the inhibition zone. Further the minimum inhibitory Concentration (MIC) was evaluated for the leaf extracts of Utleria salicifolia, Plectranthus vettiveroides and Nothapodytes nimmoniana. Further investigation with these extracts is beneficial in order to diagnose the therapeutic usage of the selective plant extracts.
