ABSTRACT OF THE DISCLOSURE Antioxidant compositions, useful for preventing de- terioration of oils and rats in rood products, are prepared by a tow-stage extraction from rosemary or sage. A crude product is first extracted from the plant material with a low-boiling solvent separable by evaporation, and is then found to be separable from contaminants that cause objectionable taste or odor, by vacuum steam or molecular distillation, with the antioxidant in a suitable oil carrier, and with the contamin- ants removed in vapor state. A special purification of the extract, for a product of very high purity except for some flavor or odor for which distillation may be needed, is at- tianable by chromatography, wherein the antioxidant material favors solvents of greater polarity than solvents in which other materials are eluted. The new antioxidant compositions are not only widely useful but appear to have unusual value in respect to vegetable oils and in respect to oil used in deep frying, and also are round of special value for inhibiting certain flavor and odor effects that occur in soybean oil.
