Embodiment 2

[0051] Example 2 Identification of common chromatographic peaks in the fat-soluble components of Danqi soft capsule GC-MS fingerprint

[0052] Through the GC-MS analysis of the samples of Danshen and Panax notoginseng prescriptions, the common chromatographic peaks were assigned according to the retention time of the chromatographic peaks and the information of mass spectrum. At the same time, the total ion current chromatogram of the fat-soluble components of Danqi Soft Capsules was analyzed and processed, and compared with the standard mass spectrum provided by the NIST mass spectral library, the qualitative results of each chromatographic peak were initially obtained. A total of 49 peaks were separated and identified. For 38 compounds, the relative percentage content of each compound was obtained by the normalized integral method, and the theoretical calculation formula is as follows:

[0053]

[0054] [In the formula, Pi represents the relative percentage (%) of the i-t...

Abstract

The invention belongs to the technical field of medicine, and particularly relates to a Danqi soft capsule fat-soluble component fingerprint, a detection method and applications thereof. According tothe present invention, the Danqi soft capsule fat-soluble component fingerprint is established by using a GC-MS method, the 13 common peaks are determined, the assignments of each common peak are clarified, and the area of the common chromatographic peaks accounts for 74.71% of the total peak area; and the Danqi soft capsule fat-soluble component fingerprint provides the scientific basis for the quality control of the preparation and the further pharmacodynamic research.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a fingerprint of a fat-soluble component of Danqi soft capsule, a detection method and application thereof. Background technique [0002] Traditional Chinese medicine is a precious heritage of the Chinese nation and the world civilization. Its curative effect has been verified by clinical practice for thousands of years, and it has played an indelible role in the reproduction of the Chinese nation. Traditional Chinese medicine preparations that are mutually restricted and coordinated by "jun, minister, assistant, and envoy" emphasize that they play a role as a whole, and most of them are not aimed at a certain target, nor are they simple additions of several components. The detection of a single component alone reduces the The accuracy and specificity of identification cannot represent the overall efficacy of traditional Chinese medicine preparations, nor can it refl...
