Evaluation of Toxicity on Mice and Artemicidal Activity of Bauhinia monandra Leaf Lectin (BmoLL) | Chapter 05 | Theory and Applications of Microbiology and Biotechnology Vol. 1

Aims: This work aimed to determine the toxicity of Bauhinia monandra leaf lectin (BmoLL) to mice and Artemia salina.

Study design: BmoLL was purified from the leaves of B. monandra through affinity chromatography and tested against mice and A. salina in order to evaluate its toxicity.

Methodology: The lectin purification was performed through saline precipitation and chromatography onto a guar gel column. The acute toxicity of BmoLL was evaluated using female mice during 14 days. Toxicity of BmoLL to A. salina larvae was also evaluated.

Results: BmoLL did not induce death or weight loss of mice at 2000 mg/kg b.w.; additionally, the lectin did not affect the survival of A. salina at the assayed concentrations (250–1,000 µg/mL).

Conclusion: BmoLL is an interesting molecule to investigate pharmacological applications due to its low toxicity according to the two models used in this work.
