Chemical composition and antibacterial activity of the rhizome oil of Hedychium larsenii.
The composition of essential oil from the rhizomes of Hedychium larsenii M. Dan & Sathish was examined by GC-FID and GC-MS techniques. 99% of the oil consisted of monoterpenoids. Sesquiterpenoids were present only in negligible quantities. Linalool and 1,8-cineole were identified as the major components. The oil showed moderate antibacterial activity against Gram-positive and Gram-negative bacteria.
