The effect of temperature on aloin extraction was investigated from 30 0C to 500C. Fig. 8 shows that, with increase in
temperature, the extraction of aloin was increased. This increase can easily be attributed to higher solubility of aloin at
higher temperature. The kinetic energy as well as diffusivity of solvent increased with temperature, and thus solvent
penetrated better inside the cellular matrix leading thereby faster release of the aloin molecules. Within 30 minutes, around
90 % extraction of aloin was observed at 40 0C, and 92 % at 50 0C respectively.
