杂志文章abstract::An HPLC/DAD/ESI-MSn method was established to characterise flavonoids in the seeds of Sophora alopecuroides L. All the flavonoids exhibited abundant [M-H]- ions, which triggered data-dependent multistage mass spectrometry fragmentations. Characteristic UV spectra were used to confirm flavonoid subtypes. In total, 22 f...
