Chengdu King-tiger Pharm-chem Tech. Co., Ltd has passed the ISO9001: 2008 quality management system certification.

All of the staff of Chengdu King-tiger believes that quality is our life. Therefore, from the selection of raw material, plant production, product testing to product warehousing, packaging and transportation, all of the procedures are in strict accordance with GMP requirements.

Our quality control department is equipped with advanced precision instruments, such as HPLC/GC/UV, etc. Full-time quality control staff keeps records of every inspection data for every batch such as active ingredient, loss on drying, ash content, heavy metal, residual solvent and microorganism.

The items that cannot be self inspected by our company, such as ETO, Pesticide Residues, PAHs, Mycotoxins, Alkaloids, etc., will be regularly sent to an internationally recognized third-party Laboratory for testing. So as to ensure product quality.

Test report and COA was provided with the product.

Our products were also tested by SGS, Eurofins, Intertek, TUV too.

ETO is an organic compound with the formula C₂H₄O. It is a cyclic ether and the simplest epoxide: a three-membered ring consisting of one oxygen atom and two carbon atoms. Ethylene oxide is a colorless and flammable gas with a faintly sweet odor. Because it is a strained ring, ethylene oxide easily participates in a number of addition reactions that result in ring-opening. So it could combine with bacterial protein molecules, hydroxyl, carboxyl group in enzymes, nucleic acid, produce alkylation effect, irreversible destruction of the metabolism of bacterial cells, so as to achieve sterilization effect.¹ >>

Polycyclic aromatic hydrocarbons (PAHs) refer to those compounds containing two or more benzene rings.

PAHs are recognized as the main organic pollutants affecting human health, due to its toxicity, genotoxicity, mutagenicity and carcinogenicity, which can cause a variety of harm to human body, such as damage to respiratory system, circulatory system, nervous system, liver and kidney.

The sources of PAHs are divided into natural sources and artificial sources. Natural sources are mainly formed in the biosynthetic process of land, aquatic plants and microorganisms. >>

Pesticide residue is defined by the World Health Organization as “any substance or mixture of substances in food for man or animals resulting from the use of a pesticide and includes any specified derivatives, such as degradation and conversion products, metabolites, reaction products, and impurities that are considered to be of toxicological significance.”Chengdu King-tiger has a special process for removing agricultural residues to control agricultural residues within the required limits.

Plant extract is a kind of product that takes plants as raw materials, according to the needs of the final product, through the physical and chemical extraction and separation process, directional acquisition and concentration one or more active ingredients in plants, without changing the structure of the active ingredients. Therefore, in terms of its material composition basis, in addition to whether the content of the index components reaches the standard, we should also pay attention to whether other active ingredients in the original plants are retained, this is an important aspect to judge the quality of a plant extract product, even the authenticity. >>
