Description and Uses

The allergen eudesmanolide sesquiterpene lactone was isolated from elecampane (Inula helenium L.). With dehydrocostuslactone and costunolide, it is a component of the (sesquiterpene) lactone-mix, used to detect sensitization to Compositae.

Alantolactone has been used:

• in cell viability assay
• to examine the percentage of multicentrosomal mitosis in low and high passage human embryonic stem cells (hESC)
• in assessment of degranulation
