A method comprising the step of treating meat and meat products, including fish, poultry, fish products, and poultry products, with a stabilizing amount of rosemary extract or rosemary extract in combination singly or collectively with tocopherols, ascorbic acid, citric acid, or sodium tripolyphosphate, prior to exposure of the meat or meat products to ionizing radiation, enhances the flavor and shelf life thereof. In addition, the active antioxidant ingredients of rosemary extract may be used individually or collectively as a replacement for rosemary extract, these being carnosic acid, carnosol, and rosmarinic acid, which have been found equivalent to or superior to rosemary extract itself for purposes of the present invention when used in the concentrations set forth herein.

The present invention relates to a composition for treating acne comprising an antimicrobial / anti-inflammatory polyphenolic molecule(s) including quercetin and rosmarinic acid in combination with salicyclic acid and / or salicylate salts in a topical and / or cosmetic delivery vehicle. The invention further relates to a method for treating acne by topically administering one of the compositions in an amount therapeutically effective to reduce the redness and blemishes associated with acne.

The invention discloses a comprehensive extraction technology of rosmarinic acid, ursolic acid, oleanolic acid and carnosic acid. The comprehensive extraction technology comprises the steps of (1) preprocessing raw materials; (2) performing reflux alcohol-extraction; (3) carrying out primary separation; (4) separating out rosmarinic acid; (5) separating out ursolic acid; (6) separating out oleanolic acid. According to the comprehensive extraction technology, the process is simple, the operation is convenient, industrial production can be easily carried out, and meanwhile, the purpose of synchronously extracting rosmarinic acid of rosemary, ursolic acid, oleanolic acid and carnosic acid is achieved, and the active ingredients of rosemary can be extracted to the maximum; the rosmarinic acid, ursolic acid, oleanolic acid and carnosic acid respectively have the purity exceeding 30%, 25%, 20% and 25%.

This invention relates to a production technique of perilla-derived rosmarinic acid which is accessible for large-scale industrial production. Perilla leaves serving as raw materials are dipped in acidic water and the mixture undergoes filtration with the extracted liquid adsorbed and desorbed in macroporous adsorption resin; the desorbed liquid is vacuum distilled to obtain romarinic acid with a purity of 10%; the 10%-purity rosmarinic acid product is extracted with petroleum ether and the organic phase is vacuum distilled to obtain rosmarinic acid with a purity of 50%; the 50%-purity rosmarinic acid product is gradient eluted with ethanol solutions of different concentrations in adsorption resin and the 95% eluent is vacuum-condensed and crystallized to produce a rosmarinic acid product with a purity of 95%. This invention has the advantages of simple production technique, easy operation, low cost, variable product types, security and reliability and therefore it is applicable in producing food additives, medical intermediates and cosmetics.

The invention discloses a production technology employing a ultrasonic countercurrent extraction process and a membrane separation (molecular sieve) process to acquire two antioxidants from Rosmarinus officinalis L. The production technology comprises adding 30 to 85% of edible alcohol into fresh rosemary branches and leaves, carrying out a ultrasonic counter current extraction process for a mixture of the edible alcohol and the fresh rosemary branches and leaves to obtain an extracted liquid with a solid-to-liquid ratio of from 1:10 to 1:30, and carrying out a membrane separation (molecular sieve) process to separate two antioxidant agents consisting of a rosemary fat-soluble antioxidant agent (comprising carnosic acid as a representative) and a rosemary water-soluble antioxidant agent (comprising rosmarinic acid as a representative) from the extracted liquid, wherein a heating time of the extracted liquid can be reduced through the membrane separation (molecular sieve) process thus a conversion ratio of rosmarinic acid to carnosol is reduced. A content of carnosic acid in the rosemary fat-soluble antioxidant agent is increased through a CO2 supercritical extraction process. The rosemary water-soluble antioxidant agent (comprising rosmarinic acid as a representative) is separated from a liquid obtained through a concentration process under reduced pressure and a solid-liquid separation process, and a content of rosmarinic acid in the rosemary water-soluble antioxidant agent is increased through recrystallization from ethanol. The production technology has the advantages of simple processes, low energy consumption, high production efficiency, production safety, and no harmful residual solvent due to single edible alcohol usage during all production processes.

The invention relates to a composition of prunella plant extracts, a preparation method and pharmic use of the composition. The activity components of the composition of the prunella plant extracts are composed of total triterpenes and total phenolic acid, wherein, the extract of the total triterpenes contains 10.0 to 45.0 wt percent of ursolic acid and 50.5 to 98.0 wt percent of the total triterpenes; the extract of the total phenolic acid contains 21.5 to 65.0 wt percent of rosmarinic acid and 70.5 to 99.0 wt percent of the total phenolic acid. The invention also relates to a preparation method and medical application of the composition.
