This research was conducted with the maceration extraction continuing by test toxicity against the shrimp larvae of A . salina Leach (BSLT). The result of the toxicity test then proceeds with the test reagents and phytochemicals with thin layer chromatography for positive test of compound phytochemicals. Thin-layer chromatography using eluen n-hexane: ethyl acetate (7: 3) to ethanol extract and n-hexane: ethyl acetate (17: 3) for n-hexane extract. Data on toxicity of A. salina Leach analyzed by probit analysis to find out the value of LC 50 on each extract.
