- W2350346523 abstract "The fragmentation behavior of a series of diterpene quinones related to tanshinone,isolated from Salvia miltiorrhiza Bunge,Salvia przewalskii Maxim.Var.mandarinorum Stib.and Salvia trijuga Diels,Was studied by low and high resolution mass spectrometry.The general fragmentation pathways of these compounds were proposed.An unusual loss of oxygen atom directly from the molecular ion was observed in cases of some hydroxy-substituted analogs.A comparison of the spectra of przewaquinone B(2) and hydroxytanshinone Ⅱ-A(7) with those of their derivatives,such as acetates (3,6) and quinoxalines (13,14),coupled with high resolution data and metastable measurement by defocusing technique,allowed us to postulate that the oxygen lost originates from the hydroxyl group as a result of intramolecular group interaction with the neighboring quinone functionality." @default.
