Abstract

Honey inhibits esterolytic and proteolytic activity of trypsin from Aedes aegypti, Culex pipiens quinquefasciatus, and cattle. The inhibitor is heat stable and only a portion of the inhibition capacity is lost from the honey by dialysis. Glucose, fructose, and sucrose have no effect upon trypsin but ascorbic acid and riboflavin are inhibitory while gluconic acid is an activator. Nectar from lilies but not from honeysuckles inhibits C. pipiens quinquefasciatus trypsin.
