Synthesis, Spectroscopic and Fungicidal Studies of Copper Soaps Derived from Mustard and Soyabean Oils and their Urea Complexes

Rashmi Sharma, Meenakshi Saxena and Nisha Sharma

Colloidal surfactants have become one of the most important requirements in day to day life, and have great importance in modern engineering and pharmacological fields. Copper soaps derived from mustard and soyabean oils and their urea complexes have been synthesized using direct metathesis. The synthesized copper soaps and their urea complexes have been confirmed by UV, IR, NMR and ESR spectral analysis. The antifungal activities of copper soaps derived from mustard and soyabean oils and their urea complexes have been evaluated by testing against Alternaria alternata and Aspergillus niger at different concentrations by agar plate technique. The effect of solvent has been excluded by complete evaporation. It has been observed that the activity increases with the increase in the concentration of the solution. It has been observed that complexes show higher activity than pure soaps, which suggests that complexes are more powerful antifungal agent. The toxicity of copper soaps and their urea complexes are found in the order:
