The use of plant extraction as natural and safe preservatives, have been highly recommended for the improvement of the microbiological and sensory quality of food.  In the present investigation, the dried fruit of  Ficus lyrata  Warb was subjected to bio preservative to chicken carcass. This study aimed to characterize the ethyl acetate extract on the phytochemical compound, antioxidant activity, antibacterial activity, to determine the toxicity of the extraction with lethal dose (LD 50 ) value and to study the application of the extract as chicken carcass preservative. The result showed that the fruit extract has phenolic compounds, flavonoids and tannins. Gas Chromatography Analysis resulted that the extract contains catechin, luteolin-6.8-C-diglukoside and Orientin.  DPPH and clear zone analysis showed that the extract has a high of antioxidant and antibacterial activity. The acute toxicity analyzes showed that the extract of  Ficus lyrata  Warb fruit has not the LD 50  below the concentration of 15000 mg/kg weight, that means the extract was practically non-toxic material. The application of extract to chicken carcass preservation had resulted the pH of carcass in the range 5.51—5.98 and decreased the temperature from 26 to 24 o C and effected to inhibit of chicken carcass decay for 2 hours.  The extract of  F. lyrata  Warb fruit also inhibited the bacterial growth until 2.4 x 10 6  CFU/g within the 12 hours of storage and increased the tenderness of carcass to 0.6 N. Based on the observed characteristics, it was obtained that the use fruit extract as a natural preservative can extend the shelf life of fresh chicken carcasses.
