Abstract

Guava, papaya and soursop are among several tropical fruits that contain antioxidants. The study was conducted to investigate the health-promoting effect of these fruits on Sprague-Dawley rats. The parameters determined were total antioxidant status, alanin aminotransferase (ALT), aspartate aminotransferase (AST), total protein, albumin, globulin, urea, creatinine, total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C) and high density lipoprotein-cholesterol (HDL-C). TAS level in supplemented (guava, papaya and soursop) group were significantly higher (p <0.05) compared to the control group. Supplementation of guava, papaya and soursop puree did not affect the ALT and AST levels. Significant difference (p <0.05) was observed between control and supplemented groups for total protein, albumin and globulin levels. The total cholesterol level was significantly reduced (p <0.05) in guava and soursop at medium and high dosage compared to control group. Rats supplemented with papaya puree at all dosage exhibited significantly higher (p <0.05) level of HDL-C compared to control group. Supplementation with these fruits will increase the antioxidant and HDL-C level in blood serum of rats, which will improve health to a better status.
