Pyrolysis of 10 kg of salak seed {Salacca zalacca)produces liquid smoke with 10% yield.Fractional distillation of 1 kg of salak seed liquid smoke under the temperature of 150-180 ℃ gave percent yield as much as 13% from a fraction named'F3'Mortality test for the fraction'F3'with concentration of 1000 ppm and 100 ppm gave 100% mortality to Artemia salina Leach larvae.The fraction'F3'was then analyzed with Gas Chromatography-Mass Spectrometer,which then showed as much as 18 compounds identified in the chromatogram,those 18 compounds were grouped into three:acetic acids and the derivatives,phenols and the derivatives,ketones and the derivatives.Those three groups of compounds are predicted to possess toxic activity and capable in killing Artemia salina Leach larvae with LC50 = 23.44 ppm.
