    Abstract

    Identification and antibacterial activity of the essential oil of leaves Piper crocatum Ruiz & Pav from Magelang were carried out. The oil w as obtained by hydrodistillation and analyzed by GC–MS. The essential oil yield 0.727% (v/w). Identified compounds were classified in two groups monoterpene and sesquiterpene. Monoterpenes were α–pinene, α- thujene, sabinene, β-mirsene, and also camphene, while sesquiterpene was trans- caryophyllene. Antibacterial activity of the essential oil tested with an agar diffusion method against Bacillus cereus, Staphylococcus aureus (gram positive) and Eschericia coli, Pseudomonas aeruginosa (gram negative). MIC for B. cereus, S. aureus were 1% , 0.25%, respectively, while MIC both E. coli dan P. aeruginosa were 0.75%. Antibacterial activities of the essential oil compared with amoxi xilin for B. cereus, S. aureus, P. aeruginosa and E. coli were 0.0008%, 0.0013%, 0.0015%, and 0.0016%, respectively . The essential oil showed less antibacterial activities than antibiotic synthetic amoxi xilin. Keywords: Essential oil, Piper crocatum Ruiz & Pav., antibacterial activity .
