The influence of ultrasound application on the extraction (UE) of the cake after sunflower seed pressing was studied. Three different solvents were used for extraction in the Soxhlet apparatus: n-hexane, petroleum ether and extraction petrol. Petrol for extraction showed the highest yield. It has been shown that the using of ultrasound improved the extraction kinetics in the initial period – washing, and in the second period – the diffusion of oil from the mass of the cake. The parameters of the non-stationary diffusion model with and without the use of ultrasound were k' = 0.039 min-1, k' = 0.026 min-1 and b' = 0.713, i.e. b' = 0.589, respectively. Oil yield was also slightly higher in the ultrasonically supported extraction.
