Vetiver oil (VO) was assayed for its antioxidant, anticarcinogenic and termiticidal properties. At the concentration of 10_l/ml, the DPPH radical scavenging effect of vetiver oil (93%) in antioxidant activity test was higher than that of 1mM BHT (73%) and equivalent to 1mM _-tocopherol (93%). At 100ppm in cancer cell lines, vetiver oil inhibited the growth up to 89% of SiHa cervical cells, 88% of CaSki cervical cells and 89% of MCF-7 breast cancer cells. Besides, vetiver oil was found to possess strong termiticidal activity against the Formosan subterranean termite Coptotermes formosanus. Vetiver oil decreased termite tunneling at concentration as low as 5_g/g sand, and entirely inhibited termites’ tunneling and paper consumption at concentrations higher than 25_g/g sand
