High-performance liquid chromatography–atmospheric pressure chemical ionization (APcI+)-time-of-flight mass spectrometry studies revealed that all-trans-β-carotene and the dibutyrates of all-trans-violaxanthin and 9-cis-violaxanthin were the main carotenoids in ‘Ataulfo’ and ‘Manila’ mango fruit mesocarp. The concentration of these carotenoids in the mesocarp was measured during fruit ripening and correlated with colorimetric changes of mesocarp and epidermis. The lowest and highest concentrations of all-trans-β-carotene, all-trans-violaxanthin and 9-cis-violaxanthin (as dibutyrates) during the ripening of ‘Manila’ mango were 0.25 × 10−3 to 35.57 × 10−3, 0.40 × 10−5 to 31.97 × 10−3 and 0 to 16.81 × 10−3 g kg−1 of fresh mesocarp, respectively. For ‘Ataulfo’ they were 2.55 × 10−3 to 39.72 × 10−3, 0.16 × 10−3 to 15.00 × 10−3 and 0.21 × 10−3 to 7.48 × 10−3 g kg−1 of fresh mesocarp, respectively. The concentration of these carotenoids increased in an exponential manner during fruit ripening in ‘Ataulfo’ and in an exponential or second-order polynomial manner in ‘
