英文摘要：

The structures of phenylethanoid glycosides in plant extract from Plantago asiatica were successfully analyzed and identified by electrospray ionization multi-stage tandem mass spectrometry （ESI-MS^n） in the some interesting losses. The rapid identification of the phenylethanoid glycosides in plant extract of Plantago asiatica was developed.
