The toxicity of the plant Moschosma polystachyum was evaluated against mosquito Culex quinquefasciatus. The crude leaf extract and active compound octacosane showed negligible mortality against early third instar larvae of Culex quinquefasciatus. The 24 h LC(50) value was observed at
Journal of colloid and interface science, 322(2), 516-526 (2008-04-24)
The adsorption of simple organic molecules to mineral surfaces was investigated by Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) and by solution chemical analysis. Salicylic acid, myristic acid or octacosane were deposited from water or hexane onto gamma-alumina and kaolinite
