Abstract

Boesenbergia stenophylla, locally known as Jerangau Merah, is a native wild ginger in Borneo Highlands, Sarawak. It is commonly used by the local as a traditional medicine for various diseases. The purposes of the current study are to investigate the phytochemicals and evaluate the antibacterial activities of methanolic B. stenophylla rhizome extract against Bacillus sp., Staphylococcus sp., Citrobacter sp. and Enterobacter sp. The rhizomes of B. stenophylla were extracted with pure methanol using Soxhlet method at 64°C for 8 h. The antibacterial properties of methanol extract were assessed using disc-diffusion assay. Phytochemical assays analysis revealed the presence of alkaloids, terpenoids, steroids, saponins, flavonoids and phenols. The antibacterial activity revealed that the extract had high to moderate inhibition against the growth of Bacillus sp. and Staphylococcus sp. at 100 mg/mL, with inhibition zones of 16.3 mm and 11.3 mm, respectively. Thus, the methanolic extract from B. stenophylla has potential to act as antibacterial agent.
