Silymarin Extracted By Ethanol is a mixture of flavonoid lignans derived from the seeds of silybummarianum, a plant of the genus Asteraceae. Its main components include flavonoids such as silibinin, isosilibinin, dehydrosilibinin, silymarin and silibinin. Silymarin has hepatoprotective and choleretic effects and is mainly used for the treatment of liver diseases. Secondly, it also has obvious anti-lipid peroxidation, anti-radiation, scavenging free radicals, anti-stomach ulcer and other effects. It has good effects in lowering blood lipids, preventing and treating atherosclerosis, preventing cerebral ischemia, and resisting platelet aggregation. Non-toxic, non-teratogenic and mutagenic.

At present, there are two main extraction methods of Silymarin Extracted By Ethanol, one is organic solvent extraction method, and the other is alkali extraction and acid precipitation method. Among them, in the prior art, the organic solvent extraction method usually adopts the steps of first pulverizing silymarin seeds, extracting oil and fat by supercritical fluid extraction, then extracting with ethanol, and extracting the extract through supercritical CO2 extraction to remove impurities, and then obtaining silymarin . The problem with this method is that after crushing the silymarin seeds, the oil cannot be completely extracted, which will have a certain impact on the purity of the subsequent extraction of silymarin; another technique is to shell the silymarin seeds first, and then use water. The silymarin is extracted from the silymarin shell to avoid the influence of the oil in the silymarin seeds, but this method needs to be shelled separately, and then the silymarin shell must be softened, soaked and other procedures before the extraction of silymarin can be carried out, which greatly increases the Extraction process, increased extraction time cost and economic cost.

Silymarin Extracted By Ethanol is a flavonoid lignan compound, which is extracted from the seed coat of the medicinal plant silymarin of the Compositae family. It is yellow powder and slightly bitter. The main components are flavonoids such as silibinin, isosilybin, silibinin and silymarin. Main effect: protect liver, improve liver function, promote bile secretion and reduce inflammation. Prevent liver damage caused by alcohol, chemical toxins, heavy metals, drugs, food toxins, environmental pollution, etc., and promote the regeneration and repair of liver cells. Therefore, it is called "natural hepatoprotective medicine". As a strong antioxidant, it can scavenge free radicals in the human body and delay aging. In addition, silymarin has the effects of anti-radiation, preventing arteriosclerosis, and delaying skin aging. It is widely used in medicine, health care products, food and cosmetics and other products, and can also be used in animal husbandry as a feed additive, with unexpected effects.
