| Abstract: | Objective] The aim of the research was to isolate and identify the chemical component of Cynanchum komarovii.Method] The extract from C.komarovii treated with AB-8 macroporous adsorption resin was further isolated by the methods such as column chromatography.The isolated compound was characterized by the means of mass spectrometry(MS),infrared spectrum(IR), nuclear magnetic resonance(NMR) spectra and so on.Result] The isolated compound was white acicular crystal with mp of 90～92 ℃.The EI-MS map of this compound showed the molecular ion peak was 238(M),base peak was m/z 238 and fragment peak was m/z 77,which proved the existence of benzene ring in the molecule. 1HNMR map revealed the signals of different types of protons in the molecular structure and their chemical shift stations.Conclusion] The chemical component of C.komarovii was 3,5-dimethoxy-4-hydroxyl methyl cinnamate,with molecular formula of C12H14O5 and molecular weight of 238. |
