ABSTRACT

Nowadays, our society is facing different problems just like the increasing price of medicines. That is why the researchers thought to have an experiment about the antibacterial ability of Buyo leaves. Buyo, (Piper betel L.), is a green leafy vine growing as a ground cover or small climber and that is very similar in growth habits to pepper. The plant refers warm, humid conditions but can tolerate some drought. The plant, generally to tender to grow outside of the tropics. In Malungon, Sarangani Province, Buyo is very abundant and the native people said that it can be an alternative medicine in curing different sickness. The mature Buyo (Piper betel L.) leaves were collected from Purok Santan, Malandag, Malungon, Saranggani Province. The collected leaves were washed, dried between filter papers and air-dried. The leaves were cut into small pieces and soaked using 95% ethanol in an Erlenmeyer flask. After 48 hours, the extract was filtered using filter paper and isolated by rotary evaporation. A total of two species of bacteria were utilized namely; Escherichia coli and Staphylococus aureus. There were three replicates in each bacterium. The aim of the present study is to investigate the antibacterial activity of Buyo (Piper betel L.) leaves extract against E. coli and S. aureus. According to the result of the experimentation, the researchers therefore conclude that Buyo (Piper betel L.) leaves extract is potential in inhibiting E. coli and S. aurues bacteria.
