In-vivo Anti-plasmodial Activity of Ethanol Tetracarpidium conophorum Seed Extract and Its Anti-typhoidal Activity In-vitro

Aim: This study was conducted to assess the in-vivo anti-plasmodial activity of ethanol Tetracarpidium conophorum seed extract and its anti-typhoidal activity in-vitro.

Study Design: Experimental study.

Methodology: Standard methods were conducted to determine the acute toxicity test of Tetracarpidium conophorum seed ethanol extract, determination of Body Weight and Temperature of Mice, determination of antibacterial activity of Tetracarpidium conophorum seed crude extract and antibiotic sensitivity testing of clinical and typed Salmonella Typhi isolates

Results: There were no signs of toxicity such as paw licking, sleeping, reduced activity, respiratory distress observed in mice and there were no mortality. Changes occurred in the weight of mice in group 1 (mice treated with 200mg/kg) from 19.71g to 14.50g wherein significant increment was observed only from day 3 to 4 (18.67g to 16.00g), group 2 (mice treated with 400mg/kg) 19.71g to 16.00g). The ethanol extract of Tetracapidium conophorum were all resistant to typed isolates of Salmonella typhimurium and clinical isolates of Salmonella typhimurium at 6.01±0.10 mm. Ciprofloxacin (5 µg) had the highest zone of inhibition at 32.50±2.50 mm against typed Salmonella typhimurium while tetracycline (30 µg) had the least at 15.50±0.50 mm.

Conclusion: This study has revealed the anti-plasmodial efficacy of Tetracarpidium conophorum seed. Findings have shown that the ethanol seed extract of T. conophorum relatively possess anti-plasmodial and anti-typhodial activities compared to the positive antibiotic susceptibility of Salmonella typhi. Auxiliary evaluation must be conducted to establish the anti-typhoidal activity of ethanol T. conophorum extract in-vivo.
