Toxicity Test of Softcoral Lobophytum sp Against Artemia salina Shrimp, L Using the Brine Shrimp Lethality Method

Marine biota resources as a potential asset that can be used into various products including pharmaceutical products because they were a natural ingredient that very rich in biologically active compounds with a unique structure. Softcoral Lobophytum is one of the marine biota that has the secondary metabolites which can be useful in pharmacology field. The purpose of this study is to test the toxicity of the soft coral extract of Lobophytum sp as an anti-cancer biopotential. This research is using the Brine Shrime Lethality Test (BSLT) method, with laboratory experiments. Solfcoral samples were taken from Bunaken Island that using purposive sampling method. The test concentrations using 10, 100, 500 and 1000 ppm. The analysis toxicity using probit analysis for minitab program. The results showed that the increasing of concentration was followed by the increasing of the mortality number of the animal testing. The results of probit analysis obtained an LC50 value of 9.98 ppm. These results indicate that the bioactive substance of softcoral Lobophytum sp has the potential as an anti-cancer compound.Keywords: Soft coral, Lobophytum sp, anti cancer, Artemia salin
