The paliasa (Kleinhovia hospital Linn.) is one of the plans that contained chemical compounds of secondary metabolites and used as a medicine. Kloform extract from the stem skin paliasa have a high bioactivity against Arthemia salina Leach; (LC5 164.55 g/ml). The study was to identificated metabolite secondary compounds of kloroform extract at stem skin palias and toxicity against Arthemia salina Leach. One compound was identificated namely-sytosterol steroid compound. The compound purified by flask chromatography and identificated with infra red (IR) Spectroscopy. The compound have a toxicity against Arthemia salina Leach. Â Keywords: paliasa, Kleinhovia hospital Linn., toxicity
