Abstract

Pogostemon cablin or Patchouli is a bushy herb of the mint family which grows in tropical climate. It is a herbal that shown interesting pharmacological activities such as antifungal and antibacterial. The scent of Patchouli is heavy and strong and the major constituent that responsible for the typical aroma is patchoulol. It also has therapeutic properties such as antidepressant, febrifuge and antiphlogistic. In this study, leaves of Pogostemon cablin were ground and the powdered leaves were extracted by using hydrodistillation method to obtain essential oil known as Patchouli oil. The percentage yield of essential oil obtained is 1.68%. It was used to evaluate the antimicrobial activity by using disc diffusion method with various concentrations ranging from 150 mg/ml to 5 mg/ml. Patchouli oil was diluted with hexane and was tested against microorganisms such as E. coli, S. aureus, S. pyogenes and C. albicans. The results showed that Patchouli oil demonstrated good antimicrobial activity against E. coli at all concentrations and moderate antimicrobial activity towards S. pyogenes above 25 mg/ml of concentrations. C. albicans possess weak antimicrobial activity and no antimicrobial activity against S. aureus. Therefore, Patchouli is very effective to inhibit the growth of E. coli but failed to inhibit the growth of S. aureus.
