Tuliposide A, a glycoside, is found in the white epidermis of bulbs. This compound is converted to tulipalin A, the allergen, by means of acidic hydrolysis. Tuliposide B, the alpha-hydroxy derivative of tuliposide A, and the hydrolytic product tulipalin B are commonly found in tulips; they are much weaker sensitizers than tulipalin A.
