摘要： A liquid chromatography-electrospray ioniza-tion mass spectrometry (LC-ESI-MS) method was developed for the analysis and identification of constituents in plant extracts from the leaves of Apocynum venetum (AV) and acidified A. venetum (AAV). The content of the compounds in AV or its acidified product was found to be variable qualitatively and highly quantitatively. Seventeen major compounds were separated and identified from AV and AAV (Table 1). The identification of the constituents (compounds 1,3, 5-7, 9-17) in the AV and AAV extracts was based on matching their LC retention time, UV spectrum and the detection of the molecular ions and the fragment ions of the compounds obtained from MS/MS experiments with those of authentic standards and data reported in the literature.
