For example, km-3-O-sophoroside (peak 31) presented MS2 fragments at m/z 447 and 429 from the loss of a glucosyl
(162 Da) and the partial loss of a sophorosyl (180 Da). Qn-3-O-sophoroside (peak 32) presented MS2 fragments at m/z 463and 445 from the loss of a glucosyl (162 Da) and the partial loss of a sophorosyl (180 Da). The parent ions of peaks 31 and32 were respectively observed at m/z 285 and 300 from the complete loss of a glucosyl
