Abstract. Anggraini T, Syukri D, Manasikan TW, Nakano K. 2020. Anthocyanin profile of Syzygium oleana young leaves and fruits using triple quadrupole mass spectrometer: Identification of a new peonidin. Biodiversitas 21: 5893-5900. Anthocyanin is pigment present in many red, blue and purple colored plants that can be used as stable food-safe colorings and also offer health benefits as antioxidants. Syzygium oleana, with its dark purple fruit and red leaves, is one hitherto unexplored source of anthocyanin. This study is the first to establish the anthocyanin profile of S. oleana leaves and fruit exploiting the speed and accuracy of Multiple Reaction Monitoring (MRM) with a triple quadrupole mass spectrometer. The anthocyanin compounds in the leaves and fruit of S. oleana were found to be derivatives of agliconpeonidin, cyanidin derivative, delphinidin. It was found that while both leaves and fruit of S. oleana contain the anthocyanin precursors cyanidin, delphinidin, petunidin, and peonidin. Fruit contains the anthocyanin malvidin and a large amount of petunidin not present in the leaves. In detail: anthocyanin found in S. oleana leaves were Cyanidin 3-galactoside, cyanidin with m/z 611, Delphinidin 3-O-β-D-glucopyranoside, and unknown peonidin. Anthocyanin in S. oleana fruits was cyanidin with m/z 449.1, delphinidin 3-O-β-D-glucopyranoside, petunidin with m/z 476, Malvidin 3-O-β-D-glucopyranoside, and an unknown peonidin. Fruit could be a better anthocyanin source and more effective as colorant than leaves, while leaves contain a stronger as yet unidentified antioxidant.

Mass Spectrometry System

A new approach was recently introduced to improve the structure elucidation power of tandem mass spectrometry simulating the MS3of ion trap mass spectrometry system overcoming the different drawbacks of the latter. The fact that collision induced dissociation in the triple quadrupole mass spectrometer system provides richer fragment ions compared to those achieved in the ion trap mass spectrometer system utilizing resonance excitation. Moreover, extracting comprehensive spectra in the ion trap needs multistage fragmentation, whereas similar fragment ions may be acquired from one stage product ion scan using the triple quadrupole mass spectrometer. The new strategy was proven to enhance the qualitative performance of tandem mass spectrometry for structural elucidation of different chemical entities. In the current study we are endeavoring to prove our hypothesis of the efficiency of the new pseudo-MS3technique via its comparison with the MS3mode of ion trap mass spectrometry system. Ten pharmacologically and synthetically important (E)-3-(dimethylamino)-1-arylprop-2-en-1-ones (enaminones4a–j) were chosen as model compounds for this study. This strategy permitted rigorous identification of all fragment ions using triple quadrupole mass spectrometer with sufficient specificity. It can be used to elucidate structures of different unknown components. The data presented in this paper provide clear evidence that our new pseudo-MS3may simulate the MS3of ion trap spectrometry system.
