| Abstract: | Five naturally bioactive compounds, belonging to the representative flavonoid and pentacyclic triterpenoid types, were separated by liquid chromatography and analyzed on-line with negative ion ESI–MS. Rutin, quercetin, and oleanolic acid in the extracts of Rosa multiflora Thunb. of China were identified by the comparison of their retention times and mass spectrometric data with those of authentic standards, and their contents were 0.22, 3.8, and 45 µg g?1 of dry weight in rose hips, respectively. Five standards, including rutin, quercetin, kaempferol, lysionotin, and oleanolic acid were investigated by MS3, which facilitate further understanding of their structures. |
