| Hazard Information | Back Directory | [Definition]
ChEBI: An organic heterotricyclic compound and guaianolide sesquiterpene lactone that is acrylic acid which is substituted at position 2 by a 4-hydroxy-3,8-bis(methylene)decahydoazulen-5-yl group and in which the hydroxy group and the carboxy group have undergone
formal condensation to afford the corresponding gamma-lactone. | [Description]
A guaianolide sesquiterpene lactone extracted from
costus oil. Dehydrocostuslactone is one of the components
of lactone-mix, with costunolide and alantolactone,
used to detect Compositae-sensitive patients.
| [Uses]
Dehydrocostus lactone is the oil extracted from Saussurea lappa is used in perfumery and in the Orient for all kinds of diseases. |
