Milk thistle contains compounds that display hepatoxic protection properties. We examined the batch extraction of silymarin compounds from milk thistle seed meal in 50, 70, 85, and 100 degrees C water as a function of time. After 210 min of extraction at 100 degrees C, the yield of taxifolin was 1.2
Seeds from milk thistle (Silybum marianum Gaert L.) contain flavanolignan and dihydroflavanol compounds that have interesting and important therapeutic activities. The recovery of these silymarin compounds generally involves a two-step defatting and extraction process using organic solvents. This
Milk thistle (Silybum marianum L.) seed meal is extracted for the flavonolignans, silychristin, silydianin, silybinin A, silybinin B, isosilybinin A and isosilybinin B, which are collectively known as the silymarin complex. To obtain the flavonolignans, the meal is usually treated with successive
Seeds of milk thistle (Silybum marianum L. Gaertner) contain silymarins and ca. 25% (w/w) of oil. A pre-treatment step involving refluxing with petroleum ether is usually performed before extraction of the silymarins using organic solvents. This paper compares the extraction of whole and defatted
The optimal conditions of supercritical carbon dioxide (SC-CO2) (160-220 bars, 40-80 °C) technology combined with co-solvent (ethanol), to recover oil, flavonolignans (silychristin, silydianin and silybinin) and fatty acids from milk thistle seeds, to be used as food additives and/or nutraceuticals,
A discussion of the historical background, development, and legal and philosophical aspects of phytotherapy as well as suggestions for its scientific basis is presented. Applications of phytotherapy for various gastrointestinal conditions are discussed for the examples of three remedies. The first

A selective acylation protocol using cerium chloride (CeCl₃) as catalyst was applied to functionalize silybinin (1), a natural antioxidant flavonolignan from milk thistle fruit, in order to increase its solubility in lipophilic media while retaining its strong antioxidant activity. The selective
The most common cause of hepatic fibrosis is currently chronic HCV infection, the characteristic feature of which is hepatic steatosis. Hepatic steatosis leads to an increase in lipid peroxidation in hepatocytes, which in turn activates hepatic stellate cells (HSCs). HSCs are also regarded as the
An oil obtained from the seeds of Saint-Mary thistle (Silybum marianum) and the drug legalon (silybinin) prepared from this plant produce an antioxidant effect on liver tissues of rats poisoned with carbon tetrachloride. Legalon (25 mg/kg) and the oil (2000 mg) reduced the level of lipid
