Figure 8. Quantitative determination of anthocyanin content
(a) Anthocyanin content from light treated (6-day) bilberry samples determined through LC-MS. The relative content expressed in arbitrary units (AU) and was calculated by normalizing the analyte peaks area with the dry weight of the samples (AU mg-1 DW). Del-Delphinidins, Cyn- Cyanidins, Pet-Petunidins, Mv-Malvidins; gal-galactoside, glu-glucoside, ara-arabinoside. (b) Total anthocyanins expressed in mg g-1 FW of cyanidin 3-glucoside equivalents after 12 days of spectral light treatment. Different letters denote significant differences among groups analyzed by one-way ANOVA followed by Turkey’s post hoc test (p-value <0,05).
