“…The [M+H] + ion at m/z 479*(* stands precursor ions generated from ESI+ mode) was detected in both RGPE and WGPE (Figure 1 C,D), which was assigned to petunidin-3-glucoside confirmed by its fragments at m/z 303 and 317 (Table 2) [26]. The [M+H] + ions at m/z 463*, 493*, 505*, 535*, 625*, 639*, and 655* could be assigned to peonidin 3-glucoside, malvidin 3-glucoside, peonidin 3-acetylglucoside, malvidin 3-acetylglucoside, petunidin 3-p-coumaroylglucoside, malvidin 3-p-coumaroylglucoside, and malvidin 3-(6-O-caffeoyl) monoglucoside (Figure 1 C,D (Table 2), respectively [26][27][28]. Of which, peonidin 3-glucoside and peonidin 3-acetylglucoside were detected in both RGPE and WGPE, while malvidin derivatives and petunidin 3-p-coumaroylgluside only found in RGPE ( Table 2).…”
