Cranberry and suspicious lingonberry dietary supplements anthocyanin profiles. Trace A (CB14) represents an authentic cranberry anthocyanin profile (as found in Lee 2013). The rest (B–D) are to demonstrate the difference in anthocyanin profile of other cranberry supplement samples, either containing artificial colorant (B, CB18), low anthocyanins with beet juice (C, CB20), or species adulterated lingonberry dietary supplement (D, LB2; presumably cranberry based on anthocyanin profile authentic lingonberry only contain the first three eluting peaks with peak 1 as the dominant; see Lee and Finn 2012). Peak assignments are 1 – cyanidin‐3‐galactoside, 2 – cyanidin‐3‐glucoside, 3 – cyanidin‐3‐arabinoside, 4 – peonidin‐3‐galactoside, 5 – peonidin‐3‐glucoside, and 6 – peonidin‐3‐arabinoside.
