UPLC-TOF-MS Characterization and Identification of Bioactive Iridoids in Cornus mas Fruit

Figure 2

Accurate mass spectra (mass-to-charge, ), in ESI negative mode, of phytochemical peaks identified in C. mas fruit by Agilent TOF detector. (1) Numbers 1–10 represent peaks to be characterized, that is, tartaric acid (1), malic aicd (2), citric acid (3), gallic acid (4), chlorogenic acid (6), a flavonoid glycoside rutin (9), and four iridoids, loganic acid (5), loganin (7), sweroside (8), and cornuside (10). (2) Accurate mass-to-charge ( ) is labeled on the top of each peak.
