What is the principle of identification of the major classes of compounds in raw medicine?

Pharmaceutical identification is based on the National Pharmacopoeia, ministry and local drug standards and relevant information provided or documented standards for medicinal drugs, medicinal drugs or test products for authenticity, purity, quality and excellence of the test.

The authenticity appraisal of medicinal products includes identification of the original plant (animal), identification of traits, microscopic identification, physical and chemical identification, and biological testing. Pharmaceutical purity test is to check the sample with or without impurities and whether the amount exceeds the prescribed limit.

Impurities, including medicinal plants (animals), non-medicinal parts, organic impurities and inorganic impurities. Inorganic impurities are generally checked by sieving and ash, acid insoluble ash quantification and other methods to determine.

The quality of raw medicine goodness check is including moisture, leachate, active ingredient content determination, in order to determine whether the quality of the test product is in accordance with the specified requirements.

Sampling of medicinal herbs:

Sampling of medicinal herbs refers to the method of selecting samples of medicinal herbs for testing. The representativeness of the sampling directly affects the correctness of the test results. Therefore, attention must be paid to all aspects of sampling.

1, before sampling, should pay attention to the name, origin, specification grade and package style is consistent, check the integrity of the package, cleanliness, and the presence of water, mold or other material contamination, etc., detailed records. Where there are abnormalities in the package, should be tested separately.

2, from the same batch of biopharmaceutical packages to take samples for testing principles are as follows: the total number of packages of biopharmaceuticals in less than 100.
