Fig. 2 in Discovery of a stable vitamin C glycoside in crab apples (Malus sylvestris)

Fig. 2. Left: PCA (Pareto scaling with 95% confidence interval) of the LC-MS analyses of extracts from four fruit of each of nine apple accessions: green triangles = M. sylvestris, red circles = M. domestica, purple Xs = M. sieversii. Right: PCA of molecular features showing that M. domestica accessions were characterised by polyphenols (red), M. sieversii by fatty acids (blue) and M. sylvestris by dihydrochalcones (green). A molecular feature tentatively identified as an ascorbyl glycoside (top left) was also associated with two M. sylvestris accessions.
