Product Introduction:
Milk thistle is a kind of traditional herb in China since thousands of years ago. Scientific name is Silybum marianum (L.) Gaertn which widely planted in Inner Mongolia and the Northeast of China. Its flower has a good ornamental value, its seeds can be used as herb ingredients. We select best quality seeds which own high content of active ingredients silymarin. Silymarin is the most effective ingredients in milk thistle seeds extract. Silymarin are mainly devided into 4 components, that is silibinin(silibinin A&silibinin B), isosilibinin, silidinian and Silicristin.
Silymarin has great effects on heat-clearing and detoxifying, soothing the liver and promoting bile flow. It is commonly used as ingredients for liver protection products, in addition, milk thistle extract also has anti-inflammatory, anti-cancer, and cardiovascular activity protective effects. It is also considered to be a very good raw material for feed and pet health food.

Production Process:
Milk thistle seeds→Oil expression→Extraction(adding solvents)→Concentration→Degreasing(adding Hexane)→Drying→Crushing→Sieving&Mixing→Packing→Finished product.
What’s the difference for milk thistle seeds extract if using different solvents?
As we know there are mainly 3 solvents for extracting silymarin from milk thistle seeds in production. Different solvents make different price. Under same specification, price rank from cheap to expensive: milk thistle extract by acetone<milk thistle extract by ethyl acetate<milk thistle extract by ethanol. According to different market trending and customer preference, you could choose the best.
Based on exporting data from main factories about milk thistle extract, the best seller is milk thistle extract by acetone, then milk thistle extract by ethanol. If for specific specification, that is silymarin 80%UV&30%HPLC, then 80%UV&50%HPLC, sum of silybin and isosilybin, and silybin with higher content.
What’s the difference of GEM milk thistle extract?
We always pick up the fine raw material milk thistle seeds to extract the final products silymarin. It is a must that raw material supplier test their milk thistle seeds according to GB Standard. We control all harmful substance from the origin which keep the final extract with excellent quality. What’s more, during the whole production process, we have a strict control about solvents residue to lower it much as we can. For standard, we can meet USP or EP standard like pesticides residue, ETO, hexane residue according to customer’s request to make your supply chain with more safety and reliable.
FAQ:
1: How can I get a sample?
We can offer 20-200g free sample for your testing based on different products.
2: MOQ(Minimum Order Quantity)
It is ok for 1kg-10kg for trail order, for bulk order, MOQ is 25kg.
3: How do you control like pesticides residue, heavy metal, microbio, physical index or other Hazardous substances for each product?
We control them from raw material, will ask raw material supplier to test. After all items are qualified, materials are accepted by us. For heavy metal, microbio and physical index like assay finished products, we test in factory lab, for pesticides residue and other index we test it in third lab such as SGS and Eurofins or based on customer’s request.
4: When I will get reply for my inquiry?
Our sales will reply you within 24hours, if it is very urgent, please call us directly.
