Comparison of antibacterial activity of essential oil and ethanol extract of kencur (kaempferia galanga linn.) Rhizomes

---

Kaempferia galanga Linn., also well known as Kencur in Indonesia is one the spices of which rhizome is used widely in Indonesia and find many uses in food, pharmaceutical and cosmetics industries. The objective of this research was to compare the antibacterial activity of essential oil and ethanol extract of K.galanga rhizomes. The essential oil was obtained through water and steam distillation, while the ethanol extract was obtained through solvent extraction. Antibacterial test was done against Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive) in various concentration; 1%, 10%, 50% and 100%, by using agar disc diffusion method. The inhibition zone of 6.0-10.0 mm was found towards E.coli, and 6.0-12.0 mm towards S.aureus. The chemical components in the essential oil and the ethanol extract were identified qualitatively by using gas chromatography and mass spectrometry (GC-MS). Both of the essential oil and the ethanol extract have antibacterial components.
