Abstract (en)

[origin: WO0126472A1] An increase in specific antioxidant activity of extracts from rosemary <i>Rosemarinus officinalis</i> is obtained by the use of a blend of tetrafluoroethane and an organic solvent in the extraction process. A blend of tetrafluoroethane, acetone and methanol improves total yield. A tetrafluoroethane and acetone blend has higher efficacy but comparatively lower yields. The methods yield a liquid and oily antioxidant extract that is readily mixed with a liquid product such as soybean oil for addition to animal feeds and human food. The methods simultaneously yield pharmaceutical-grade essential oils in high yields.
