Abstract

The objective of the present study was to evaluate the toxic effect of Averrhoa carambola (star fruit) juice at different storage conditions in Sprague Dawley (SD) rats. Twenty female rats weighing 180 +/- 20 g were randomly assigned into four groups with five rats per group (n = 5). First group served as the control group, fed with distilled water (vehicle). Second, third and fourth groups were orally treated with juice of A. carambola stored for 0, 1 and 3 h respectively for 14 days. Cage-side observations were done daily after each treatment. Body weight, food consumption and water intake were recorded on day-0, day-3, day-7 and day-14. All rats were fasted overnight prior to blood collection through cardiac puncture on day-15. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), urea and creatinine in blood serum were measured. Data were analyzed using Dunnett's test. From the results obtained, there was no lethality found and LD(50) could not be determined. Increment of ALT levels (P<0.05) was reported in those rats treated with A. carambola juice stored for 3 h. On the basis of these results, we can conclude that A. carambola juice stored for 0 hand 1 h are safe to be consumed. However, juice stored for 3 h exerts toxic effect on rat liver at hepatocellular level.
