The CMC of CTAB was decreased by the increase in concentration of drug and same was in the case of temperature. Thermodynamic properties like free energy,enthalpy and entropy were determined in the presence of drug at diffrerent temperatures,which showed that free energy of the system in presence of drug at different temperature was favoured.

A variety of pharmacologically active compounds were identified including hexadecanoic acid, oleic acid, vaccinic acid, and pthanlic acid. All the tested samples were found fairly effective in antibacterial assay, P. aeruginosa was found more susceptible to ethyl acetate fraction with inhibition of 69.5 %, while B. subtilis was found completely resistant. Similarly the growth of M. canis and F. solani were moderately inhibited by M. buxifolia. The maximum (50%) antifungal effect was observed in case of ethyl acetate fraction against F. solani, While no leishmanicidal activity was found in the entire tested samples. Yet the use of this plant can be validated in the management of different bacterial and fungal infections.
