HPLC profiling of anthocyanins and flavonols in GLRaV-3-infected symptomatic and virus-free green leaves. The chromatograms show profile of anthocyanins from (a) virus-free and (b) GLRaV-3-infected leaves and profile of flavonols from (c) virus-free and (d) virus-infected leaves. None in (a) indicates no anthocyanins detected in virus-free, green leaves. Anthocyanins identified in (b) are: 1 = Cyanidin-3-glucoside; 2 = Malvidin-3-glucoside; 3 = Peonidin-3-O-6-coumarilated. Flavonols identified in (c) and (d) are: 1 = Myricetin-3-glucoside; 2 = Unknown; 3 = Unknown; 4 = Unknown; 5 = Quercetin-3-glucoside; 6 = Quercetin-3-glucuronide; 7 = Unknown; 8 = Unknown.
