1 2 2 2 1 2 The essential oils obtained by hydrodistillation of the leaves and rhizomes of Zingiber spectabile Griff. were analysed by capillary GC and GC-MS. Fifty-six constituents were identified in the leaf and rhizome oils, respectively. The most abundant components in the leaf oil were β-caryophyllene (21.3 %) and βelemene (12.5 %) while the rhizomes yielded an oil rich in zerumbone (59.1 %). The antibacterial activities of both oils against multidrug resistant strains and food borne pathogens were evaluated by the agar disc diffusion assay technique. The leaf oil was inactive against all tested microorganisms while the rhizome oil exhibited weak activity against Escherichia coli, Methicillin-resistant Staphylococcus aureus, Pseudomonas aeruginosa, Shigella sp. and Salmonella enteritidis. 167 23rd-25th June 2010 3rd ICYC 2010 Universiti Sains Malaysia NAT-O7 SCREENING BIOACTIVE POTENCY AND COMPOUND ISOLATION OF DICHLOROMETHANE EXTRACT OF PARMELIA TINCTORUM (DESPR EX.

1 Irma Kartika Kusumaningrum and Wahyudi Priyono Suwarso 2 1 2 Chemistry Department, Faculty of Science and Mathematics, Malang State University, Indonesia Chemistry Department, Faculty of Science and Mathematics, University of Indonesia, Indonesia E-mail: email@example.com There are many problems about treatment of diseases caused by antibiotic -resistant microorganisms, unpredictable character of cell mutation and difficulties faced by pharmaceutical laboratories in their search for new effective molecules. It is very important to discover tuberculosis and cancer effective drug, because until now mortality caused by tuberculosis and cancer patie nt are high. Screening and isolation of active ingredients from nature is one way to get the new drug...
