Sub-chronic oral toxicity assessment (90 days) of ethanolic fraction of leaves of Neurocalyx calycinus (R. Br. ex Benn.) Rob. in rodents: A lesser known ethnomedicinal plant from the Cholanaickan tribal community, India


The objective of the present study was to evaluate the safety of long term consumption of ethanolic fraction of Neurocalyx calycinus leaves (NCEF) in rodents. The NCEF was subjected to detect the presence of various phytoconstituents. In acute oral toxicity study, graded doses of NCEF was administered in mice and were observed up to 14 days. In sub-chronic oral toxicity study, NCEF was administered to Wistar rats at doses of 50, 500 and 1000 mg/kg b.w. per day for 90 days and after that, observed up to 28 days. NCEF showed the presence of alkaloids, steroids, phenolics and glycosides. In acute toxicity study, there was no mortality and no behavioural signs of toxicity at the highest dose level (6400 mg/kg b.w.). In sub-chronic oral toxicity study, there were no significant difference observed in the consumption of food and water, body weight and relative organ weights. Haematological, serum biochemical, hepatic oxidative stress marker analysis and urine analysis revealed the non-adverse effects of prolonged oral consumption of NCEF. The histopatho-logic examination did not show any differences in vital organs. Based on our findings, NCEF, at dosage levels up to 1000 mg/kg b.w., is non-toxic and safe for long term oral consumption.
