Product Description

Product Description

 

Basic Information

 

• Chemical Name and Structure: The main component of milk thistle powder is silymarin, which is a flavonolignan compound. Silymarin is a mixture composed of multiple isomers, mainly including silybin, isosilybin, silydianin, silychristin and other components. Structurally, these components all possess the typical structural features of flavonoids, such as containing multiple phenolic hydroxyl groups and benzopyran ring structures. This structure endows silymarin with various physiological activities like antioxidant properties.
• Appearance and Properties: Milk thistle powder is usually light yellow to brown in color. The color variation may be related to factors such as the source of raw materials and processing techniques. The powder is fine in texture, odorless, and has a slightly bitter taste.

 

Physical and Chemical Properties

 

• Solubility: Silymarin has poor solubility in water but relatively good solubility in some organic solvents. For example, it has a certain solubility in organic solvents such as ethanol and acetone. This makes these organic solvents often used for extracting and dissolving silymarin during the extraction and preparation of formulations. However, when considering its application in food or pharmaceuticals, attention should be paid to the issue of organic solvent residues.
• Stability: Silymarin is relatively sensitive to light and heat. Under light conditions, changes may occur in its chemical structure, resulting in the loss of active ingredients. In a high-temperature environment, decomposition and other situations may also arise. Therefore, during storage and transportation, appropriate measures such as light-proof and low-temperature storage should be taken to maintain its stability.
• Acidity and Alkalinity: The stability of silymarin also varies under different acidity and alkalinity conditions. In an acidic environment, its structure is relatively stable, but in a strongly alkaline environment, hydrolysis and other reactions may occur, affecting its chemical properties and physiological activities.

 

Sources and Production Methods

 

• Natural Sources: Milk thistle powder mainly comes from the seeds of Silybum marianum, which is a plant in the Asteraceae family. The seeds of Silybum marianum are rich in silymarin. Firstly, the seeds of Silybum marianum are collected and cleaned to remove impurities, and then preliminary milk thistle powder is obtained through mechanical processing methods such as pulverization.
• Extraction Methods: In order to obtain high-purity silymarin, the solvent extraction method is often adopted. Utilizing the solubility of silymarin in organic solvents (such as ethanol), the pulverized seeds of Silybum marianum are soaked and extracted with solvents such as ethanol. After extraction, through processes such as filtration, concentration, and drying, high-purity milk thistle powder is further purified.

 

Quality Standards and Specifications

 

• Purity Standards: Different applications have different purity requirements for milk thistle powder. For milk thistle powder used in pharmaceutical production, a relatively high purity is required, and generally, the content of silymarin is required to be above 80%. For milk thistle powder used in the field of health products, the purity requirement is relatively lower, but it usually also needs to meet certain standards, such as a silymarin content of about 50% - 70%.
• Impurity Limitations: There are strict limitations on the content of heavy metals (such as lead, mercury, arsenic, etc.). For example, the lead content generally does not exceed 1 mg/kg, the mercury content does not exceed 0.1 mg/kg, and the arsenic content does not exceed 1 mg/kg. Meanwhile, there are also corresponding standards for pesticide residues, microorganisms and other indicators to ensure the safety and quality of the product.

 

Uses and Application Fields

 

• Medical Field: Silymarin has a protective effect on the liver. It can improve liver function and has an auxiliary therapeutic effect on various liver diseases such as hepatitis and fatty liver. Its mechanism of action is mainly achieved through multiple pathways such as antioxidant, anti-lipid peroxidation, and stabilization of liver cell membranes to protect the liver. For example, in the treatment of drug-induced liver injury, silymarin can alleviate the damage of drugs to liver cells.
• Health Product Industry: Due to its health care effect on the liver, milk thistle powder is widely used in the production of health products. It appears in forms such as capsules and tablets and serves as a daily liver health supplement to help people prevent liver diseases, especially for people with bad living habits such as frequent drinking and staying up late, and it has certain health care value.
• Cosmetics Industry: The antioxidant property of silymarin also has applications in the cosmetics field. It can be added to skin care products such as creams and lotions to help resist oxidative aging of the skin, reduce the damage of free radicals to the skin, and make the skin healthier.
