Abstract
Boesenbergia stenophylla, otherwise known as Jerangau merah in Malay is an extremely rare species of medicinal plant belonging to the Zingiberaceae family. It can be found in high altitude place and it is endemic to Borneo. It has been claimed to have medicinal properties against bacteria which cause food poisoning. The local usually use it to cure stomach-ache, food poisoning and alcohol intoxication. This study was conducted in order to determine the antimicrobial activity of B. stenophylla by using agar well diffusion and minimum inhibitory concentration (MIC) against Escherichia coli (E. coli) strains EDL 993. and ATCC 25922, Pseudomonas aeruginosa (P. aeruginosa) strains ATCC 27853 and Bacillus cereus (B. cereus) strains ATCC 33019. A high antimicrobial activity was shown against P. aeruginosa in both agar well diffusion and minimum inhibitory concentration assay while the lowest antimicrobial activity against B. cereus. On the other hand, extracts that used hexane and ethyl acetate as a solvent system show high antimicrobial activity compared to the extract using water as a solvent system. In addition, extraction from stem shows more antimicrobial activity compared to rhizome and leaf. The extracts from B. stenophylla have shown antimicrobial activity and further studies should be carried out in vivo on the medicinal properties of the plant.
