Described is a composition for the prevention and treatment of symptoms associated with ethyl alcohol consumption. The composition comprises silymarin, salicin, at least one B vitamin, magnesium, molybdenum and manganese. Treatment of symptoms associated with the consumption of ethyl alcohol involves ingesting the described composition prior to, during, or after the consumption of the alcohol.

This invention discloses drug-delivery compositions, methods of making prodrugs, and methods of drug delivery using a self-assembled gelator. The backbone of the gelator can contain a drug or prodrug, such as acetaminophen or salicin. Additional drugs or agents can be encapsulated in the gelator. Enzymatic or hydrolytic cleavage can be used to release the drugs.

The invention belongs to the technical field of chemical engineering and particularly relates to an extract prepared by using willow barks or willow branches as raw materials, and a method for preparing high-purity salicin, aiming at providing a method for extracting high-content salicin from the willow barks or the willow branches. The method comprises the following steps of: (A) taking the willow barks or the willow branches as the raw materials and carrying out extraction by using an aqueous or alcoholic solution, (B) filtering an extracted solution, (C) carrying out resin adsorption separation on a filtrate, (D) decolorizing, and (E) crystallizing and is characterized in that: an ultrafiltration manner is adopted to filter when the filtration is carried out in the step (B), the extracted solution is firstly filtered by using a 100-500 kD ultrafiltration membrane and then is filtered by using a 5-10 kD ultrafiltration membrane, and the average membrane fluxes are respectively controlled at 100-190 LMH and 20-24 LMH. According to the method provided by the invention, the steps of extraction and ultrafiltration are adopted in coordination with the processes of adsorption, decolorization, crystallization and the like, the content of the obtained salicin can reach 99.0%, the yield is high, the cost is low, and the water and a small amount of alcohol which are used in production can be recycled, so that the cost is lowered, the pollution to the environment caused by organic solvents is reduced, and the implementation of industrialization is facilitated.

The invention belongs to the technical field of extraction and separation of active ingredients from a plant, and specifically relates to a method for purifying salicin in white willow bark by using an ultrasonic extraction-macroporous resin combined technology. The method is characterized in that: the purpose of the method is to overcome disadvantages of relatively low extraction rate, low extraction purity and the like of the conventional technology, and to provide a method for purifying salicin in white willow bark by using an ultrasonic extraction-macroporous resin combined technology. The method has the following advantages that: the ultrasonic extraction is adopted, such that advantages of low extraction temperature, high efficiency, short extraction time, and the like are provided, the salicin extraction rate is substantially improved, and the extraction time is shortened; the macroporous resin is adopted to adsorb the salicin, such that the good adsorption effect on the salicin is provided; and an ethanol water solution is adopted to extract salicin, such that the dissolving effect is good, the salicin consumption is reduced, and the yield is increased.
