The studied plants in this research belongs to the family Zingiberaceae which is well known source of many spices and medicinal drugs. Many plants belonging to this family have been remained unexplored. Ginger and curcumin are also from this family which is used in India on regular basis as main spices due to their marvelous properties. The comparative studies helps to examine and explain if particular characteristic traits are followed by all the members belonging to same family. And also to discover the one which is best of all. The present investigation was performed to detect in vitro antibacterial activity of essential oils from leaves of Roscoea purpurea and Zingiber chrysanthum. The essential oil was obtained by hydro distillation of plants using Clevenger apparatus. The Antibacterial effect was examined by Well diffusion method against Escherichia coli, Bacillussubtilis, Staphylococcus aureus and Pseudomonas aeruginosa. The present study has shown that both the essential oils are effective against gram positive and gram negative bacteria. The present study results that these plants can be explored as new bacteriostatic agents.
