The aim of this research is to determine of total flavonoid content in the Buni fruit (Antidesma bunius L. Spreng) extract. The extract was produced by stratified maceration method with the different solvent, i.e n-Hexane, Ethyl acetate and ethanol. The analysis of chemical compound using chemical reagent and Thin Layer Chromatography (TLC) method. The method is used to determines total flavonoid contains Buni fruit (Antidesma bunius L.) extract was based on the amount of Rutin Equivalent (RE) were used. The result shows that the flavonoid content higher in the n-Hexane extract is 10.72 %, then ethyl acetate extract is 7.9 % and 3.56 % ethanol extract was counted to or as a Rutin.

Mahoni is a medical plant which have the potential as drug. The aims of this research were to analysis phytochemical content and to test the toxicity of ethanol extract of seed from Mahoni. The Phytochemicals that analyzed were total phenolic, total flavonoid and condensed tannin. Toxicity test was assessed using BSLT method. Extraction was done by maseration method using ethanol as the solvent. In BSLT method, the shrimp larvae were placed in a series of test solution of varied concentration. The value of LC50 were obtained based on calculation of shrimp larvae lethality percentage using probit analysis. LC50 values of ethanol extract were 0,95 ppm.
