Rapid Screening of Chemical Constituents in<i> Rhizoma Anemarrhenae</i> by UPLC-Q-TOF/MS Combined with Data Postprocessing Techniques

<div>The specific fragmentation process of chalcone flavonoids, take 2′,4′,4-trihydroxychalcone as an example: the fragment ion of<i> m/z</i> 255 [M-H]<sup>−</sup> is molecular ion and the fragment ions at<i> m/z</i> 135 and 119 resulting from separation of A and B rings.</div>
