摘要： The present invention relates to a novel liquid-liquid extraction process of a bio-oil obtained by an improved thermochemical process. This extraction process gives rise to two distinct phases: an organic phase, with bio-oil of energetic added value, and an aqueous phase, where the following can be obtained by chemical compounds with added value: lactic acid, formic acid, hydroxymethylfurfural, furfural, levulinic acid, monosaccharides, disaccharides and compounds with antioxidant properties, among others.

摘要： The present invention relates to a method for producing cannabigerol and purifying it from a reaction mixture. The present invention also relates to the cosmetic use of cannabigerol for the inhibition of tyrosinase activity and/or the reduction of melanin production in the skin, in particular for reducing pigmentation of the skin, preferably for the improvement of the appearance of the skin in case of hyperpigmentation, lentigo or vitiligo. Furthermore, the present invention relates to cannabigerol for use in a therapeutic method for the inhibition of tyrosinase activity and/or the reduction of melanin production in the skin, preferably for use in a therapeutic method for the treatment and/or prevention of malign skin disorders, in particular skin cancer.

摘要： Methods of isolating phenols from phenol-containing media. The methods include combining a phospholipid-containing composition with the phenol-containing medium to generate a combined medium, incubating the combined medium to precipitate phenols in the combined medium and thereby form a phenol precipitate phase and a phenol-depleted phase, and separating the phenol precipitate phase and the phenol-depleted phase. The methods can further include extracting phenols from the separated phenol precipitate phase. The extracting can include mixing the separated phenol precipitate phase with an extraction solvent to solubilize in the extraction solvent at least a portion of the phenols originally present in the phenol precipitate phase.

摘要： Various aspects of the disclosure relate to methods and systems for extracting oil from plant material. A system may comprise a gas moving device, an extraction chamber, and a condensation surface. Oil of the plant material may be volatized in the extraction chamber and then propelled by the gas moving device to the condensation surface to be collected. In various embodiments, the systems and methods allow the extraction of oil from plant material with little or no solvent.

摘要： Various processes for the separation of a mixture containing dichlorophenols are described. In various aspects, the present invention relates to separation processes that produce an extract enriched in 2,4-dichlorophenol content and an extract enriched in 2,5-dichlorophenol content. The present invention further relates to various processes that integrate with these separation processes, such as a process for producing 3,6-dichloro-2-methoxybenzoic acid (dicamba) or salt or ester thereof or a process for producing 2,4-dichlorophenoxyacetic acid (2,4-D) or salt or ester thereof.
