The liquid chromatogram of Opuntia humifusa fruit water extract (OHE) and tandem mass spectrometry (MS/MS) data of major phytochemicals. Phytochemicals in the OHE were analyzed using UPLC-Q-TOF MS equipped with an Acquity UPLC BEH C18 column (2.1 mm × 100 mm, 1.7 µm) and negative mode ESI. Major phytochemicals were identified by using the UNIFI scientific information system with various LC/MS online databases. Solid spots indicated mass fragments of major phytochemicals.
