- Product Description
Bulk Milk Thistle Extract Powder – Highly Effective Liver-Protecting Natural Active Ingredient
Shaanxi Hongda has been making silymarin for 24 years and is one of the bulk milk thistle powder makers in China. We get our milk thistle extract powder from the mature achenes of the milk thistle plant (Silybum marianum), which is in the Asteraceae family. Milk thistle extract powder has flavonoid lignans, which are a fine powder that can be pale yellow to brownish-yellow.Our silymarin can be produced in concentrations ≥30%, and organic milk thistle powder disperses rapidly in organic solvents such as ethanol and acetone. Pure silymarin powder can also be stably suspended in aqueous phase using emulsification technology, meeting various applications such as beverages, soft capsules, functional powders, and skin creams.
We ensure that the silymarin content is consistently above 80% (UV), while the silybin content is >30%. We control residual solvents to an extreme level of <50ppm (far superior to USP standards). Hongda provides not only raw materials but also a guarantee for your products to enter global chain pharmacies (such as Walgreens and Boots).

Advantages of Milk Thistle Extract:
1. High Activity Concentration: Hongda's silymarin is at least 80% and silybin is at least 30%. This implies it protects the liver and has antioxidant properties.
2. Dual-mode extraction and low-temperature freeze-drying: The supercritical CO₂ method ensures a high recovery rate, while the low-temperature freeze-drying method preserves the thermosensitive flavonoid structure, preserving activity over 90%.
3. Micronized powder: The particles are less than 12µm in size, dissolve and spread quickly, and can be used with liquids, semi-solids, and solids.
4. Natural source: We get our raw materials for green milk thistle from nature, which makes sure that the production process is green and healthy.
5. Full-spectrum testing: Hongda's CNAS lab does HPLC, UV, GC-MS, and microbiological testing on every batch to make sure they are all the same.
