A comparison of the pigments inFuchsia extorticata pollen with the pigments extracted from the unusually coloured blue-black “fuchsia” bee pollen confirms the New Zealand tree fuchsia as the source of the bee pollen. The pigments were identified as thep-trans-coumaro- ylated derivatives of delphindin-, petunidin and malvidin-3-O-glucosides and delphinidin-3- O-(p-cis-coumaroyl-glucoside). The anthocyanins are accompanied by several flavonol glyco- sides; kaempferol-3-sophoroside, quercetin-3-sophoroside and kaempferol 3-neohesperido- side.
