The antibacterial activity of Alpiniagalanga(L.)Willd. leaf extracts prepared from methanol, acetone, chloroform, ethanol, petroleum ether extracts ofAlpiniagalanga were checked against pathogens isolated from wound isolates like Burn, Accident, Skin, Abscess, trauma etc viz. Bacillus subtilis ,Escherichia coli, Klebsiellapneumoniae, Pseudomonas aeruginosa, , Staphylococcus aureus and Streptococcussps, Proteus sps, Staphlococcusaureus, using Agar well diffusion method. Acetone extracts have shown excellent anti bacterial activity towards all the pathogens with plant extract ranging from 5-25mg/ml and size of zone (mm) ranged 8-26 mm (12.5 mg) concentration and 8-35 mm (25 mg), respectively. The ethanolic extract contained the highest concentrations of total phenolic compounds (92.40 ± 0.83(mg TAE/g) and flavonoids (13.78 mg TAE/g) and Tannins 48.80 ± 0.83(mg TAE/g). So, Alpiniagalanga can be quite resourceful for the development of new generation drugs.
