Abstract

The invention discloses a method for detecting bufadienolide components in a Liushen pill. The method comprises the following steps: preparing a reference sample solution; preparing a test sample solution; and calculating the content through an HPLC assay determination method and a standard curve method. According to the invention, optimal chromatographic conditions such as mobile phase composition, a chromatographic column, an elution program, detection wavelength and column temperature are screened out through a large number of experiments, and the chromatographic conditions are optimized to obtain the optimal detection conditions. The detection method provided by the invention can realize quick, accurate and reliable determination, has high specificity and favorable reproducibility, can simultaneously detect 9 bufadienolide components in the Liushen pill, and can be used for quality control on the Liushen pill, thereby having important significance for drug quality control.

Description

technical field [0001] The invention relates to a detection method of a traditional Chinese medicine preparation, in particular to a detection method of bufadienolactone components in Liushen Pills, and belongs to the field of component analysis of traditional Chinese medicines. Background technique [0002] Liushen pill is composed of musk, bezoar, toad and other traditional Chinese medicines. It belongs to the national protected traditional Chinese medicine. It has the effect of cooling and detoxifying, reducing inflammation and relieving pain. , carbuncle sore furuncle, milk carbuncle hair back, unknown swelling poison. The medicinal toad venom contained in it is the dry secretion of Bufo bufogargarizans Cantor or B.melanostictus Schneider, a Bufo family animal. Pain relief etc. According to literature reports, the main active ingredients of Bufadienolide are bufadienolactone compounds, which have significant digitalis-like effects, boosting blood pressure, respiratory ...
