Fig. 3 in Discovery of a stable vitamin C glycoside in crab apples (Malus sylvestris)

Fig. 3. LC-MS chromatograms (Instrument B, method I) of crab apple extract, commercial 2-O-α-D-glucopyranosyl L-ascorbic (4), and two AAGs produced by chemical synthesis, 2-O-β-D-glucopyranosyl L-ascorbic (2) and 2-O-β-D-galactopyranosyl L-ascorbic (2a). The traces are extracted ion chromatograms for m/z 337 [M – H]-.
