Potential for the use of ultrasound in the extraction of antioxidants from Rosmarinus officinalis for the food and pharmaceutical industry
TL;DR: Ultrasound was used to increase the extraction efficiency of carnosic acid from the herb Rosmarinus officinalis using butanone, ethyl acetate and ethanol as solvents and reduced the solvent effect so that ethanol reached a similar level of extraction efficiency to the other two when sonicated.

Influence of ultrasound on extraction of tannins from deoiled salseed cake
TL;DR: In this paper, it has been observed that the percentage of extraction is greater at lower frequencies: 78% of tannins are extracted in a 40% aqueous acetone solvent using ultrasound in only 30 min compared to 20 h with conventional techniques.
