Abstract

Isolation and identification of toxic compounds from ethanol extract of Prunus domestica L. have been conducted. Extraction of 1000 gr of plum fruit produced 128,75 g concentrated ethanol extract. The results of toxitcity tests of the extract using Artemia salina L. larvae showed the LC₅₀ value of 100 ppm. Partition of ethanol extract yielded chloroform (10,52 g), n-hexane (26,58 g), and water (52,57 g) extracts. The toxicity test showed the chloroform extract to be the most toxic with LC₅₀ of 31,97 ppm. Chloroform extract was separated by column chromatography using silica gel as stationary phase and chloroform : ethanol : water (5:4:1) as mobile phase giving three fractions. The toxicity test showed that fraction II was the most toxic with LC₅₀ of 364,74 ppm. The phytochemical test result showed  that fraction II (the active isolate) belonged to terpene groups. Analysis using UV-Vis spectrophotometer showed three peaks at 241,  409, and 668 nm, showing the possibility of the presence of funtional groups of C-H aliphatic, C-O alkoholic and C=O, respectively
