The method used is Brine Shrimp Lethality Test (BSLT), the ethanol and n-hexane extract of this bark terap (A. odoratissimus) were tested. The results showed that the secondary metabolic component from terap (A.odoratissimus)was toxic. The LC50 from the extract of terap (A. odoratissimus) that dissolved in Ethanol was 82.0008 and The LC50 from the extract of terap (A.odoratissimus) that dissolved in n-Hexane was 383.3533 Keywords:Artocarpus odoratissimus, BSLT (Brine Shrimp Lethality Test), LC50
