Table 1

Content of ascorbic acid and its contribution to antioxidant capacity of different extracts (E1–E3, without (A) or with (B) ascorbate oxidase treatment) obtained from sequential elution of a metaphosphoric preextract (PE) of rose hips. Data are presented as mg ascorbic acid/g dw rose hip powder, mg ascorbic acid/mL extract, and FRAP antioxidant capacity mmol Fe2+/L extract (mean ± standard deviation).
