The research of isolation of sambung nyawa (Gynura procumbens Lour) stick  and its anti bacteria activities  on  Escherichia  coli,  Staphylococcus  aureus  and  Samonella  typhimurium  have  been conducted  on  their    1,  4  and  7  months  harvesting.  Sambung  nyawa  stick  dried  and  extracted  by ethanol to obtain the ethanol extract, and then tested to three kind of  bacteria with the concentrationof 100 and 50 mg/l, and  the compound group testing also have been done. Ethanol extract separated by column chromatography using chloroform, ethyl acetate and methanol as solvent to obtain the active compound. The fraction of column chromatography tested again on the bacteria. The result showed that sambung nyawa stick contain of antibacterial compound was very active on S.aureus compared  two  others  with  the  clear  zone  was  13.5  mm  same  as  size  of  positive  control  (amoxilin antibiotic).  The  harvesting  age  of  7  month  more  active  as  antibacterial  and  the  compound  group testing   positive than age   1 and 4 months.
