%X Volatile oil of dried rhizome of Kaempferia galanga obtained by water distillation was determined for its chemical components using gas chromatography and mass spectrometry (GC-MS). The major chemical constituents were identified as ethyl-p-methoxycinnamate (31.77%), methylcinnamate (23.23%), carvone (11.13%), eucalyptol (9.59%) and pentadecane (6.41%), respectively. Antimicrobial activity of the volatile oil was tested against various microbes using agar disc diffusion method with the inhibition zones from 8.0- 31.0 mm. Brine shrimp toxicity of volatile oil exhibited an EC50 value of 26.84 ¦Ìg/ml; whereas the volatile oil was inactive for antioxidant activity (IC50 >100 ¦Ìg/ml).
