KCN inhibition of lipoxygenase in purple, green, and white eggplants.

Lipoxygenase activity in three cultivars (purple, green, and white) of eggplant, Solanum melongena, were compared. Activity was greatest in the purple and lowest in the white variety. In contrast to reports that NaCN did not inhibit eggplant lipoxygenase, in these studies cyanide completely inhibited the enzyme in all three varieties.
