1.CAS No.
CAS No is the abbreviation of Chemical Abstracts Service Number.The same meaning is (Synonyms): CAS Number; CAS#; CAS Registry Number;
Unique numbers assigned to a specific chemical (identified by its chemical name) by the American Chemical Society and indexed in Chemical Abstracts published by Chemical Abstracts Service in the US. CAS numbers are widely used for accurate identification of materials and quick retrieval of their chemical and safety information.
2.Chinese Medicine
A traditional system of medical treatment based on the principles of Yin and Yang in China, involving suchtreatments as acupuncture and the use of a range of drugs derived from animal and vegetable sources
3. CoA
CoA is the abbreviation of Certification of Analysis
The same meaning is (Synonyms): Certification of Analysis
An authenticated document, issued by an appropriate authority, that certifies the quality and purity of pharmaceuticals, and animal and plant products being exported.
4.Standard Herbal Extract
A standardized herbal extract is an herb extract that has one or more components present in a specific, guaranteed amount, usually expressed as a percentage. The intention behind the standardization of herbs is to guarantee that the consumer is getting a product in which the chemistry is consistent from batch to batch. This practice has developed out of the drug model of herbal medicine, in which modern scientists have attempted to identify the components of a plant that have definite pharmacological activity in the body.

5.Ultraviolet
Synonyms: UV
The range of invisible radiation wavelengths from about 4 nanometers, on the border of the x-ray region, to about 380 nanometers, just beyond the violet in the visible spectrum.
6.HPLC
Synonyms: High Performance Liquid Chromatography
HPLC is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out the column.
HPLC has been used for manufacturing (e.g. during the production process of pharmaceutical and biological products), legal (e.g. detecting performance enhancement drugs in urine), research (e.g. separating the components of a complex biological sample, or of similar synthetic chemicals from each other), and medical (e.g. detecting vitamin D levels in blood serum) purposes.
