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...
