Embodiment

[0092] Chromatographic conditions and system suitability test Octadecylsilane bonded silica gel was used as filler; glacial acetic acid solution (1→100)-acetonitrile (63:37) was used as mobile phase, and the detection wavelength was 275nm. Column temperature: 30°C. The number of theoretical plates should not be less than 5,000 based on the calculation of the peaks A and B of dragon blood, and the separation degree between peak A and peak B of dragon blood should be greater than 2.0.

[0093] Preparation of Reference Substance Solution Accurately weigh the appropriate amount of reference substances of dragon blood A and dragon blood B which have been dried under reduced pressure by phosphorus pentoxide for 24 hours, add methanol to dissolve and make each 1ml containing dragon blood A 0.18mg, containing dragon blood A mixed solution of 0.04 mg of element B is obtained.

[0094] Preparation of the test solution Take about 0.25g of the powder of this product (passed through a No....

Abstract

A method for controlling quality of sangusis draconis uses liquid phase chromatography to determine contents of dracoresene A and B in Chinese traditional raw medicine of sangusis draconis simultaneously. The method includes steps of making adaptive test of chromatograph condition and system, preparing control solution, preparing test sample solution and carrying out determination.

Description

technical field [0001] The invention relates to a method for detecting raw materials of Chinese medicinal materials, in particular to a method for detecting components that can be used for quality control. Background technique [0002] Dracaena cochinchinensis (Lour.) Dracaeua cochinchinensis (Lour.) S.H.Chen is a resin extracted and processed from the lipid-containing xylem of the plant Agaveaceae. It is a commonly used traditional Chinese medicine. , mainly used for bruises, blood stasis pain, stagnation of Qi and blood in women, traumatic bleeding, and bedsores that persist for a long time. It has been included in the national drug standard WS3-082(Z-016)-99(Z). The currently implemented standard quality control only measures dragon blood B (C 18 h 20 o 5 ), the research found that the main components of dragon blood jerky are flavonoids, and it is difficult to accurately reflect the quality of the product only by controlling the amount of one flavonoid in the medicin...
