To evaluate the protective activity of fruits against liver injury, 22
different fruits were fed to rats with liver damage caused by
D-galactosamine, a powerful liver toxin.
As measured by changes in the levels of plasma alanine
aminotransferase (ALT) and aspartate aminotransferase (AST), avocado
showed extraordinarily potent liver injury suppressing activity.
Five active compounds were isolated and their structures determined.
These were all fatty acid derivatives, of which three, namely,
(2E,5E,12Z,15Z)-1-hydroxyheneicosa-2,5,12,15-tetraen-4-one,
(2E,12Z,15Z)-1-hydroxyheneicosa-2,12,15-trien-4-one, and
(5E,12Z)-2-hydroxy-4-oxoheneicosa-5,12-dien-1-yl acetate, were novel.
