Tulipalin A is the unsubstituted a-methylene-g-butyrolactone
contained in the sap of damaged tulips
(Liliaceae family) and Alstroemeria (Alstroemeriaceae
family). Tulipalin B, due to hydrolysis of tuliposide B,
seems to have a weak sensitizing capacity. | [InChIKey]

Tulipalin A is an unsubstituted -methylene-butyrolaetone
eontained in the sap of tulips, Alstroemeria spp.
(Peruvian lily) and Erythronium (dog tooth violet,
fawn-lily). Tulipalin B seems to have a weak capacities
to sensitize. | [storage]
