新疆一枝蒿有效部位主要成分的制備與鑒定
[Abstract]:Objective: to establish a method for rapid identification and efficient preparation of the main components of active parts of Artemisia annua in Xinjiang, and to provide a reference for the study of ethnic medicine. Methods: the main components of the active parts of Artemisia annua were preliminarily inferred by liquid phase high resolution mass spectrometry (LC-HRMS/MS). The names of some compounds were compared with the corresponding reference substances by HPLC, UV and MS. The undetermined compounds were separated by column and their structures were determined by liquid chromatography. Results: five compounds were isolated from the active parts of Artemisia annua and two of them were identified as Artemistein and Bauhinia. A monomer compound with a purity of 98.5% (yield of 0.35 mg/g,) was obtained. The structure of the compound was confirmed to be 6-demethoxy-4- O-methylcaptophan -7-O- 尾 -D-glucoside. Conclusion: the method established in this experiment can be used in the study of the complex material base of the national medicine, and the rapid separation, identification and preparation of the target components can be realized.
