ABSTRACT:
A process of preparing an alkaline solution of Labiatae antioxidants essentially free of lipids by agitating a solvent extract of the herb with an aqueous alkaline lower-aliphatic alcoholic or polyol solution thereof, separating the aqueous phase from the insoluble phase, and removing the alcohol from the aqueous phase by distillation to give a stable product with an antioxidant strength of 0.2 or more, having a pH above about 8.4, and having less than 75% water, preferably in the presence of a water-immiscible solvent, and a stable aqueous antioxidant solution of a Labiatae extract, consisting essentially of essentially all of the antioxidant substances present in the herb, which is preferably rosemary, sage, or thyme, with an antioxidant strength of 0.2 or more, and less than about 75% water, preferably having a pH between about 8.4 and about 11.8, and therefore useful for a wide variety of antioxidant purposes, including use in can liners and aqueous alkaline epoxy emulsions for preparing the same, are disclosed.
