FATTY ACID PROFILES OF CITRUS JUICE AND SEED LIPIDS

Fatty acids from the juice and seeds of six citrus varieties were quantitatively determined for the region C12-C26. The total number of juice acids observed ranged from eighty-one (Key limes) to one hundred and two (Eureka lemons) and the total number of seed acids ranged from sixty-two (Valencia oranges) to sixty-eight (Key limes and Eureka lemons). Thirty-eight different iso and twenty-six anteiso acids were observed for the first time in edible plant material in concentrations ranging from less than 0·001 per cent to greater than 1 per cent. These single branched acids were verified by comparison of retention times with standards and by their characteristic mass spectrographic fragmentation patterns. © 1970.
