Abstract: Atok, Benguet in Northern Philippines is highly susceptible to landslides. To mitigate the effects of landslides, revegetation, was recently introduced as a means of soil stabilization. The selection of revegetation species is crucial; they should be indigenous to the area, reproduce rapidly, and suitable for bioengineering. The choice of revegetation species is sometimes dependent on the local community. Hence, to encourage the community to use these plants, the researchers conducted this study to establish additional value, specifically for their phytochemical content and antimicrobial potential.The selected plants are Coffea arabica, Brugmansia suaveolens, Camellia sinensis, Sarcandra glabra and Coriaria intermedia, which are found in the adjacent areas of landslide scars. Results showed that Camellia sinensis have the most number of secondary metabolites. Further, the plant extracts were tested against five bacteria namely Salmonella typhimurium, Bacillus cereus, Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa using disc diffusion method. Leaf extract from C. intermedia was active against all the strains and is comparable to the results of the four antibiotics (Chloramphenicol, Vancomycin, Kanamycin and Streptomycin) used. The antibacterial potential and the presence of bioactive components of the different plants can increase the value of the plants both for economic and medicinal purposes.
