Oils from thirty-two plants were extracted using solvent extraction/steam distillation methods. All oils along with 11 blended oil mixtures were tested for their immersion oil properties for the detection of malaria parasites. The physicochemical properties required for an immersion oil including density, viscosity, refractive index and acid value of five oils namely as Ocimum basilicum, Pogostemon cablin, Papaver somniferum Ricinus communis and Valeriana jatamansi and blended mixture 6 were determined. |
