Abstract: Highlights: [•] A HPLC-ELSD fingerprint of steroid saponins was established. [•] An HPLC-ESI-Q/TOF method was established to identify steroid saponins. [•] 68 common peaks were obtained in fingerprint by HPLC-ELSD. [•] 12 common peaks were confirmed with the reference compounds. [•] 56 common peaks were tentatively assigned by HPLC-ESI-Q/TOF.
