Abstract: Cucumber (Cucumis sativus L) is a plant that is widely consumed by the people. Beside due the delicious taste of it, cucumbers also contain some compounds that can be used as a drug, one of them is to prevent cancer. This plant contains Flavonoid, Saponin, and Tanin. These three compounds are the compounds which is in certain levels can be cytotoxic. Acute toxicity is an early screening test for a specifc cytotoxic potential crop for the development of anti-cancer drugs. The purpose of this research is to know the acute toxicity of cucumber (Cucumis sativus L) methanol extract to the Artemia salina Leach larvae by Brine Shrimp Lethality Test (BSLT) method. This research method was an experimental by using BSLT method. The test animal used was the Artemia salina Leach larvae. The method of extraction was maseration method. The results of the study can be seen from the percentage of larvae mortality for each concentration of extract, those are 0 μg / ml, 250 μg / ml, 500 μg / ml, 750 μg / ml, 1000 μg / ml are 0%, 48%, 62 %, 72%, 84% and 92%. Based on the result of probit analysis with microsoft Excel showed that LC50 value of cucumber methanol extract is 201,0165 μg /ml which means this extract have potency of acute toxicity because LC50 value <1000 μg / ml.Abstrak: Mentimun (Cucumis sativus L) adalah tanaman yang banyak dikonsumsi oleh masyarakat.

Ganoderma lucidum is polyporus fungi from Basidiomycetes which can be used as traditional medicines. Toxicity test with Brine Shrimp Lethality Test (BST) method using Artemia salina was conducted to find out toxic effect of G.lucidum. An extract would have toxic effect if the LC50 < 1000 µg/ml. The aims of this experiment were to know about the toxicity level from G.lucidum with Brine Shrimp Lethality Test (BST) method and determined the concentration of fruiting body extract of G.lucidum which had the best toxicity effect in LC50. There were two extraction methods used in this experiment, first one stage extraction and then multilevel extraction with hexane, ethyl acetate, and ethanol. Each solvent was made in 1000 ppm, 500 ppm, 250 ppm, and 125 ppm. This process was repeated for three times. This experiment used G.lucidum extract which was tested to A.salina and secunder compound metabolit test from the most toxic G. lucidum was done with phytochemical analysis. The result indicated that fruiting body extract from G.lucidum could kill A.salina because all extract was positively contained alkaloid and terpenoid but negatively contained flavonoid. Fruiting body extract from G.lucidum which had lowest LC50 wass ethyl asetat extract with one stage extraction in concentration 53,70 ppm and highest LC50 was ethanol extract with multilevel extraction in concentration 501,18 ppm.
