Abstract

The invention belongs to the field of analysis of traditional Chinese medicines and specifically relates to a method for detecting the pharmaceutical composition of cassia twig and Poria cocos by using gas chromatography and fingerprint chromatography. Chromatographic conditions and system adaptability test are as follows: a capillary column is used; injection port temperature is 220 to 240 DEG C; a hydrogen flame ionization detector is used and has a temperature of 230 to 250 DEG C; column temperature is 70 to 90 DEG C which is maintained for 2 to 4 min, and then the capillary column is heated at a speed of 15 to 25 DEG C / min to a temperature of 150 to 170 DEG C and maintained at the temperature for 5 to 7 min and then is heated at a speed of 25 to 35 DEG C / min to a temperature of 240 to 260 DEG C and maintained at the temperature for 13 to 15 min; a split ratio is 20-30: 1; N2 flow velocity is 0.5 to 2.0 mL / min; and the number of theoretical plates, in terms of the reference substance of paeonol, should not be lower than 3000. The method provided in the invention can more comprehensively detect the quality of the composition, is more beneficial for controlling of the quality of the composition and has the advantages of high precision and good stability and repeatability.

Description

Technical field: [0001] The invention belongs to the field of traditional Chinese medicine analysis, and relates to a gas chromatography fingerprint detection method of a Chinese medicine composition, in particular to a gas-phase gas-phase analysis of a Chinese medicine composition made of cassia twigs, poria cocos, white peony root, moutan cortex and peach kernels as raw materials. Chromatographic fingerprint detection method. Background technique: [0002] The medicinal composition of Guizhi Fuling is made of Chinese medicine Guizhi, Poria, Paeoniae Alba, Cortex Moutan, and peach kernel. diseases such as fibroids. The capsule preparation of the traditional Chinese medicine composition has been approved for marketing by the State Food and Drug Administration of China. The generic name of the drug is Guizhi Fuling Capsule, and the drug approval number is Z10950005. [0003] The applicant of the present invention has studied the preparation process of the cinnamon twig and ...
