    Abstract: The prime aim of present investigation was focused on the <I>in vitro</I> antibacterial and GC-MS analysis of <I>Gymnema kollimalayanum</I>, a new record plant from India. The aqueous and 5 different organic solvents (chloroform, acetone, methanol, ethanol and dichloromethane) extracts were tested against both gram negative and gram positive bacterial strains by agar well diffusion assay (<I>Staphylococcus aureus</I>, <I>Streptococcus pneumoniae</I>, <I>Bacillus substilis</I>, <I>Escherichia coli</I>, <I>Pseudomonas aeruginosa</I>, <I>Proteus vulgaris</I>, <I>Klebsilla pneumonia</I> and <I>Salmonella typhi</I>). The results highlights that the chloroform, acetone and aqueous extracts exhibited significant antibacterial activity than other solvents. The results of GC-MS analysis shows ten biologically active compounds were isolated. Out of these, two compounds are reflecting the highest peak values.
