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]

clear colourless to light yellow or slightly pink | [Uses]
Very reactive Michael-acceptor; the α-methylene-γ-butyrolactone ring system exists in many natural products of biological interest | [Definition]
ChEBI: A butan-4-olide having a methylene group at the 3-position. | [Description]
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. | [Source]
a-Methylene-g-butyrolactone (MBL), also known as Tulipalin A, is found to be present in white tulips. By virtue of its
exo-methylene double bond, it can be used as a naturally
originated monomer in order to synthesize biopolymers.[1] | [storage]
Store at -20°C, protect from light, stored under nitrogen | [References]
