Abstract

The invention discloses a preparation process and a quality control method of an Eleutherococcus senticosus reference extract, the Eleutherococcus senticosus reference extract is prepared by decocting and extracting Eleutherococcus senticosus decoction pieces as a raw material, in the preparation process, the powder yield and the content of syringin which is an effective substance can be effectively controlled by reasonably controlling the decoction times, the water addition amount, the decoction time and the like, the stability of the radix acanthopanacis senticosi reference extract component is ensured, and the process is stable in operation. The quality control method can realize the stability and reliability of the preparation process of the Eleutherococcus senticosus reference extract.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine preparations and detection, and in particular relates to a preparation process and a quality control method of acanthopanax control extract. Background technique [0002] With the research and development of modern Chinese medicine preparations, the inconvenience and uncertainty in the efficacy of traditional decoction methods have become more and more prominent, and have greatly affected and restricted the application and promotion of Chinese medicine preparations in the market. In order to maximize drug efficacy, reduce toxic and side effects, and meet the clinical requirements of traditional Chinese medicine, it is the key to improve the extraction process of traditional Chinese medicine preparations and establish exclusive quality control. [0003] Acanthopanax is the dry root and rhizome or stem of the shrub plant Acanthopanax senticosus (Rupr. et Maxim.) Harms of the family Aralia...
