Fatty acids from the juice sacs of four orange varieties from early season harvest, one variety from mid- and one variety from late season, and two tangors were quantitatively determined and it was found that the five major fatty acids, viz. palmitic, palmitoleic, oleic, linoleic and linolenic, comprised more than 92 per cent of all acids. There appeared to be no correlation between the major fatty acids and the harvest season of the various orange varieties. The two tangors were distinctly different from the oranges in both their major and minor fatty acid profiles. A theory is proposed for the occurrence of specific iso- and anteiso-branched acids in citrus.
