  • Title: Profiling of iridoid glycosides in Vaccinium species by UHPLC-MS.
    Author: Heffels P, Müller L, Schieber A, Weber F.
    Journal: Food Res Int; 2017 Oct; 100(Pt 3):462-468. PubMed ID: 28964369.
    Abstract:
    The iridoid profile of four Vaccinium species was investigated using UHPLC-MS to obtain further information about this group of species for phytochemical characterization. Fruits of bog bilberry (Vaccinium uliginosum L.) showed 14 different iridoid glycosides with a total amount of 20mg/kg fresh weight (FW), whereas bilberry (Vaccinium myrtillus L.) contained 11 iridoid glycosides and a total amount of 127mg/kg FW. Highbush blueberry (Vaccinium corymbosum L.) and lowbush blueberry (Vaccinium angustifolium L.) contained none of the investigated iridoid glycosides. Among the different iridoids, the isomers scandoside and deacetylasperulosidic acid as well as a dihydro derivative thereof were described for the first time in the Ericaceae family. The p-coumaroyl isomers of scandoside, deacetylasperulosidic acid and dihydromonotropein are reported for the first time in V. myrtillus and V. uliginosum. Monotropein and its p-coumaroyl isomers were found for the first time in V. uliginosum. The comparison of iridoid profiles in bilberry fruit and juice samples revealed constant proportions throughout the juice processing. Quantification and profile determination of iridoids may be used for species differentiation and thus for authentication purposes.
