A new method based on the modified QuEChERS approach was developed for determination of phenolic compounds in passion fruit pulp (Passiflora spp.) using UHPLC-MS/MS. Studies of extraction/partitioning and clean-up were carried out using different variations of the QuEChERS method (original, acetate, and citrate) and clean-up sorbents (PSA, GCB, C18 and Oasis ® HLB).
