Dendrocalamus asper (D.asper) is one of the various species of bamboo found in Vietnam. Its wood is used to construct dwellings, and its shoot is nutritious. There is evidence of the antibacterial qualities of the bamboo shoot (Dendrocalamus asper). The main objective of this study is the antibacterial activity of D.asper shoots against bacteria. The antibacterial activity of shoot extract of D.asper was evaluated on bacterial strains like Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Vibrio parahaemolytius. Using a Soxhlet extractor, the antibacterial activity of two distinct solvents (ethanol and hot water) was produced. All studied resistant bacteria were effectively inhibited by the active antibacterial activity of the shoots' ethanol and hot water extract. Ethanol proved to be the most effective solvent in this study for extracting the active ingredient from the shoot. Most hot water extracts demonstrated bactericidal activity in various zones of inhibition, ranging from 13,44±0,84 mm to 14,78±2,04 mm. Across various zones of inhibition (14.00±0.00 mm - 16.67±1.53 mm), most ethanol extracts exhibited antibacterial activity. The highest antibacterial efficacy against Pseudomonas aeruginosa was demonstrated by the ethanol extracts.
