The selective fractionation of a yarrow extract using SAS technology was studied. The effect of pressure (10–20 MPa) at 40 °C on the precipitation was evaluated. The morphology and particle size distribution of the precipitates was analyzed. Up to a 3 fold increase of phenolics concentration was observed in the precipitates. Increasing pressure resulted in smaller particles and narrower particle distribution.
