Abstract

The invention discloses a multi-index component content measuring method for the roots of common peonies and honeysuckles in a Chinese herbal medicine compound preparation. The multi-index component content measuring method has the advantages that a chromatographic condition is used for measuring content of paeoniflorin and six caffeoylquinic acids in the Chinese herbal medicine compound preparation comprising the roots of the common peonies and the honeysuckles, simplicity and convenience in operation are achieved, and analysis data are accurate; gradient elution conditions are reasonable, and when both chromatographic peak shapes and separation degrees of target components are considered, detection time is shortened greatly; analysis time of analysts is saved due to simultaneous detection of the seven components, and working efficiency is improved; the proportion of organic phases in mobile phases is low, testing cost is lowered, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a method for determining the content of a compound Chinese medicine preparation, in particular to a method for determining the content of Radix Paeoniae Rubra and Honeysuckle in a compound Chinese medicine preparation, and belongs to the technical field of medicine. Background technique [0002] Kanggan series preparations (Kanggan Granules and Kanggan Capsules) are composed of 3 herbs including honeysuckle, red peony root, and Mianmaguanzhong. Cold caused by exogenous wind-heat. Kanggan granule implements the standard of the first supplement of the 2010 edition of "Chinese Pharmacopoeia"; Kanggan capsule implements the National Drug Standard WS of the State Drug Administration 3 -225(X-215)-2002Z. Standard items include: TLC identification of chlorogenic acid and paeoniflorin; HPLC content determination of paeoniflorin. [0003] Honeysuckle is the main drug in the prescription. The above-mentioned standards all use TLC of c...
