Aloe vera extract characterization and its protection against fenvalerate induced toxicity in Heteropneustes fossilis

Abstract

Pesticides constitute the important group of environmental pollutants since they are potent metabolic inhibitor. It is gradually being recognized that by use of natural herbs and herbal preparations in aquaculture we can deal with pesticidal problems. The present study aimed to evaluate the characterization of ethanolic extract of Aloe vera (A.vera) by IR , SEM and to investigate its immunomodulatory, antidiabetic and anticholesterol activity in H. fossilis after giving sublethal doses of fenvalerate. As blood is patho-physiological indicator, this study was performed to begin an assessment of the effect of fenvalerate on biochemistry of blood serum. In present study three sublethal doses of fenvalerate [0.25, 0.50 and 0.75 (p.p.m)] were given to test fish, H. fossilis for 15 days. After 15 days same fishes were given A.veraleafextract [(A.vera A) 250, (A.vera B) 500 and (A.vera C) 1000 (mg/kg of body wt.)] for 30 days to find its protection after intoxication of fenvalerate. Fenvalerate found harmfull in all the three doses and A.vera was protective against doses of fenvalerate.
