Quality Control

China Resource Sanjiu Medical & Pharmaceutical Co., Ltd., a company that follows its mission of 'invigorating the Chinese Nation and Advancing Toward the World', has contributed significantly to the modernization of Traditional Chinese herbs. Based on its rich manufacturing experience and quintessence of Chinese Medicine, it has successfully developed more than 400 Single Chinese Herbal Extracts and established the relevant quality control standards.

Total Quality Control
The packaged granules are tested for granulation, solubility, weight, active ingredient concentration (UV, HPLC), as well as to ensure that heavy metals, pesticide residues and microorganisms limits meet our exceptionally rigorous standards.

 


3G Compliant

GAP- Good Agriculture practice

GMP- Good Manufacture Practice

GMP- Good Management Practice


Planting

In accordance with the principles of correct growing environment and respect for local ecosystems, China Resource Sanjiu has established GAP compliant herbal farms in 10 Chinese provinces. In these farms are grown more than 300 different herbs under conditions which limit heavy metal and pesticide residues and assure consistent high quality.


Identification of Type and Quality

By means of thorough registration of place of origin, microscopic examination,and physical and chemical testing, China Resource Sanjiu ensures that the varieties of the raw herbs it uses are consistent with the standards of the TCM Pharmacopoeia. Using purity tests, careful examination of the active ingredient, and water content assay, we ensure that only the best of any herb is chosen for our extracts, For example, the common varieties of Radix Astragali on the market are Mongolian milkvetch root, membranous rnilkvetch root, and Astragalus chrysopterus bunge.

To meet the standards of the TCM Pharmacopoeia, the herb used in our extracts must be the dry root of the perennial herbaceous plant Astragalus membranaceus Fisch..) Bge. Var. mongolicus Hsiao or Astragalus membranaceus (Fisch.) Bge,
and the content of the active ingredient (C41H68O14) cannot be less than 0.04%(HPLC method).


Processing

Raw herbal materials are processed before the extractive process using thousands of years old TCM methods. This ensures that the healing qualities of the herb are enhanced and toxic effects reduced. For example, before being used to replenish the liver and kidneys in order to enrich the vital essence and blood, Fleece Flower root is processed by traditional methods to avoid purgative side effects that can damage spleen and stomach.


Extraction

For different herbs we use the direct cross design to determine soak Lime, extraction temperature, and the number of extractions repeated. l\/lost herbal extracts contains a variety of active ingredients, so we take care to extract all of them in order to assure maximum efficacy. Most extracts are made using the traditional TCM method of extraction with de-ionized water. For others that contain volatile oils and other special ingredients that must meet the standards of the TCM Pharmacopoeia, such as peppermint, villous amonium fruit, etc., we use the water vapor distillation or supercritical extraction processes.


Concentration

The resulting extracted liquors vary in their properties: some are thin, others dense; some stable, others readily affected by heat; some readily bubble in concentration, others do not. Thus we select the correct method of concentration and the right equipment according to the properties of the liquor and the degree of concentration required. The most common methods we use are ordinary pressure concentration, diaphragm concentration, and multi-effect concentration


Drying

We use spray drying, vacuum drying or ordinary pressure drying depending on the properties of the liquors. Spray drying is the most common process since it is very efficient and produces granules that dissolve easily. For materials that are sensitive to heat or prone to oxidation at high temperature, we use vacuum drying with the temperature strictly controlled to ensure the solubility of the granules. Finally, for fossil and crustacean herbs, minerals and other thermotolerant materials, we use ordinary pressure drying.


Granulating

Most herbal extract granules do not contain inert ingredients. If the extract is in powder form it is easily affected by moisture. When it is made into granules the integrity of the herb is preserved.


Packaging

Packing the products with aluminum-plastic composite film prevents damage from moisture, light, and worms, thus ensuring the products accurate dosage, safety and stability.
