Abstract

Investigate the bioefficency of extract from Capsicum annum on lipid content in tissues of gills and digestive glands of fresh water bivalves, Lamellidens corrianus after heavy metal (As2O3) intoxication. The bioefficency is studied on bivalves were studied under five groups. Group A bivalves was maintained as control, B group bivalves were exposed to chronic dose (LC50/10) of arsenic trioxide (2.120ppm) and Group C bivalves were exposed to respective chronic concentration of As2O3 along with extract of capssicum annum (5mg/l) upto 12 days. Lipid contents in selected tissues from each group were estimated after 6 and 12 days. Bivalves from group B were divided for recovery into two groups such as group D and E after 12 day exposure to arsenic. D group bivalves was allowed to cure naturally in normal water while E group bivalves was exposed to extract of capsicum annum (5mg/l) up to the 12 days. From each of recovery groups, gills and digestive glands of bivalves were removed and lipid contents were estimated after 6 and 12 days. The lipid level was significantly decreased on exposure to arsenic while the decrease in presence of extract was less when exposed simultaneously than when exposed individually. During recovery lipid contents recovered and the rate of recovery was faster in extract exposed bivalves as compared to those recovered in normal water. The bioefficency of extract of C.annum is discussed in the paper.
