The phenolic composition was determined in the leaves, petioles and bark tissues of male and female plants of two papaya cultivars. The same kind of phenolics were isolated from the male and female plants. However, a marked difference was observed between the plant organs of different cultivars. The important free and bound phenolics extracted after acidic and alkaline hydrolysis were caffeic acid, gentisic acid, m ‐coumaric acid, p ‐coumaric acid, salicylic acid and quercetin. Four phenolic compounds were not identified. The amounts of free, acid‐hydrolysable and alkali‐hydrolysable phenolic compounds were considerably higher in male plants.
