ABSTRACT: In this study, a catalog of β-cryptoxanthin (βCX) and its fatty acid esters (βCXFAs) in citrus fruits were constructed. The peel and pulp of
citrus fruits from nine Japanese cultivars and one foreign cultivar were
surveyed by supercritical fluid chromatography/triple quadrupole mass spectrometry
(SFC/QqQMS). In each citrus sample, the major components were βCX and its laurate ester, myristate
ester, palmitate ester, and oleate ester. However, the composition ratio of βCXFA varied with the citrus breed and
between the pulp and the peel of the fruit in most cultivars. The SFC/QqQMS
system could be used to obtain new information about βCXs and carry out further discussion
on the feature and tendency of each citrus variety.
