Abstract:
OBJECTIVE: To analyze chemical components in active fraction of Xiaozhong zhitong lotion, to clarify the material basis of its efficacy, and to provide reference for the second development of ointment preparation. METHODS: UPLC-Q-TOF-MS was adopted to analyze the chemical components of active fraction (40% ethanol elution site separated by D101 macroporous resin) of Xiaozhong zhitong lotion. The determination was performed on Hypersil GOLD aQ C18 column with mobile phase consisted of 0.1% formic acid acetonitrile (A)-0.1% formic acid water (B) (gradient elution) at the flow rate of 0.4 mL/min. The sample size was 4 μL, and the column temperature was 30 ℃. The condition of mass spectrometry was ESI detection in positive and negative scanning ion mode (ESI+/ESI-). The scanning range was 100-2 000 Da. The collision energy was 45/-45 eV, and the energy of the extended collider was 10/15 eV. The accurate molecular weight, retention time and multi-stage fragment ion information of the compounds were collected after obtaining the chromatogram, and the chemical components were identified by comparing with the mass spectrum information of reference materials and references. RESULTS: A total of 48 compounds were identified, and 9 and 39 compounds were identified under ESI+/ESI- ion mode, mainly including 10 phenolic acids, 8 phenylpropanoids, 9 anthraquinones, 3 flavones, 7 alkaloids, 5 tannins and 6 other categories. CONCLUSIONS: UPLC-Q-TOF- MS method is rapid, efficient and accurate for identify chemical components from active fraction of Xiaozhong zhitong lotion. Main chemical components of the active fraction are phenolic acids, phenylpropanoids, anthraquinones, alkaloids and tannins.
