Calixarene and ionic liquid assisted matrix solid-phase dispersion microextraction of organic acids from fruit.

•MSPD coupled with UHPLC-Q-TOF/MS was used to determine organic acids in fruit.•Calix[8]arene was used as an efficient sorbent in MSPD procedure.•The ionic liquids were applied as extraction solvents.•The proposed method was rapid, simple, low cost and high sensitivity.
