Chemical Constituents and Antimicrobial Activities of Goniothalamus Species


Medicinal and Aromatic Plants Seminar (MAPS 2008)


42nd October - 22nd October 2008

Place Held

The Legend Hotel, Kuala Lumpur


The aerial parts of Goniothalamus macrophyllus and G. tortilipetalum were collected from the Pasoh Forest Reserve and subjected to hydro-distillation for 8 h. Essential oils obtained were analyzed by GC and GC/MS analytical methods. The results showed that the oils possessed several major compounds. The twigs of G. macrophyllus contained geranyl acetate (45.5%), linalool (12.7%) and geraniol (17.0%) and the root contained cyperene (9.8%). geranyl acetate (9.4%) and camphene (7.5%). The leaves of G. tortllipetalum contained 0-cymene (43.0%), piperitone (11.5%) and 1,8-cineole (5.8 %). Antimicrobial activities of all the oils were evaluated against 11 micro-organisms including Multidrug Resistant Staphylococcus aureus (MRSA). gram-positive bacteria, gram-negative bacteria and dermatophytic fungi using single concentration test and broth micro-dilution method. All the oils inhibited the growth of the test micro-organisms studied except Pseudomonas aeruginosa (a gram-negative bacterium). The gram- positive bacteria were more sensitive to the extracts than the gram-negative bacteria and fungus. The antimicrobial activity could be due to the presence of geraniol and linalool which have been reported to have significant activities.
