acute toxic effects that occur after exposure and the content of secondary metabolites in the leaves and seeds of papaya as saponin, flavonoid and triterpenoid is over expressed as the concentration that can be lethal to fifty percent of the test population (LC50). the LC50 in this study is reported time period of 48 hours 107 ppm (107 ppm. hours). the lower the value of LC50 the more toxic the substance. although the lethal concentration varies between deference species, the relative toxicity of substances is usually constant. the lower the value LC50 will the more toxic. LC50 measurement is micrograms or milligrams of material per liter, or parts per million (ppm) of water. the lower the value, the more toxic. the result of phytochemical analys of granules of ectract from papaya (quartz papaya) seed and leaf modified by maceration with ethanol contains secondary metabolites compounds of saponin, flavonoid and triterpenoid are represented in figure 1.
