Abstract

Gedebong (Piper aduncum Linn) is a plant of Piperaceae which is commonly found in Indonesia. Piper aduncum Linn is often used for treat colic, wound treatment and insect repellents. Several previous studies have reported Piper aduncum Linn containing essential oils which have antifungal, cytotoxic and antibacterial activity. In this research, isolation, analysis of chemical components, and antibacterial activity of essential oils of Piper aduncum Linn leaves were carried out. Isolation of essential oil was obtained by water distillation method. The result showed that essential oils with a yield of 1.93% (v / b) which yellow liquid and aromatic. The chemical components of essential oil from Piper aduncum Linn leaves were analyzed by GC-MS (gas chromatography-mass spectroscopy) showed that 13 chemical components with main components were apiole (39.07%), trans-β-Caryophyllene (14.68%), valencene (8.33%), α-Curcumene (6.33%) and piperitone (9.83%). Antibacterial activity of essential oils from Piper aduncum Linn leaves tested with disk diffusion method. The essential oils from Piper aduncum Linn leaves showed the less antibacterial activity against bacteria Staphylococcus aureus and Escherichia coli respectively.
