%X Herbal plants have been believed by Indonesians to be an alternative medicine to treat illnesses. The bioactivecompounds in the plant can be derived from secondary metabolites or from endophytic and phyllosphere bacteria whichcoexist within medicinal plants. A total of 18 endophytic bacteria and 32 phyllosphere bacteria were isolated from theherbal plants of Citrus sp., Pluchea indica, Curcuma longa, Nothopanax scuttelarium, Piper crocatum, andAndrographis paniculata. About 72% of endophytic bacteria isolates have proteolytic activity and about 11% havelipolytic activity. On the other hand, about 59% of phyllosphere bacteria isolates have proteolytic activity and about19% have lipolytic activity. Phylogenetic diversity analysis was conducted by using the amplified ribosomal DNArestriction analysis (ARDRA) method and the sequence of 16S rDNA was digested with endonuclease restrictionenzymes: MspI, RsaI, and Sau961. The diversity of endophytic and phyllosphere bacterium from the samples of herbalplants was high. Bacteria isolated from the same herbal plant does not always have a close genetic relationship exceptfor the bacteria isolated from the P. indica plant which showed a close genetic relationship with each other.
