英文摘要Rubiaceae-type cyclopeptides (RAs) are one of characteristic constituents isolated from Rubia species, which are candidates of innovative anti-tumor drugs due to their significant bioactivity. However, approaches on the systematic characterization and quantification of RAs are still not available because of low contents and complicated purification. In this study, an ultra performance liquid chromatography coupled triple quadrupole tandem mass spectrometry (UPLC-QqQ-MS/MS) method was established and validated for qualitative and quantitative analysis of 14 RAs (1-14) in 20 Rubia plants from China. The separation was achieved on a Waters ACQUITY UPLC (R) BEH C-18 column (50 x 2.1 mm, 1.7 mu m) using gradient elution with a mobile phase consisting of 0.1% formic acid in acetonitrile and water. Multiple reaction monitoring (MRM) in positive mode was used to enable the selective detection of RAs from the Rubia root and rhizome extracts within 10 min. This method was proved to be specific, sensitive, precise, and accurate with the limits of detection and quantification at 0.6-11.4 ng/mL and 1.9-34.2 ng/mL, respectively, and the relative standard deviation (RSD) of the overall intra-day and inter-day precision less than 5.24%. Satisfactory recovery was obtained from 83.80% to 111.77%, with the RSD less than 5.32%. Totally, 67 samples were then qualitatively and quantitatively analyzed by this method and 51 of them were proved to contain RAs. Thereinto, R. podantha and R. yunnanensis from Yunnan were the two most abundant species. Additionally, RAs were detected in 8 Rubia species for the first time. Then chemometric approaches were revealed to explain the relationship between samples based on their contents of RAs. This study demonstrated that the method was not only useful for RAs source discovery and chemotaxonomy of Rubia species, but also could be extended to standardization of RAs medical materials and their new drug research and development.
