Celery Seed Identity & Plant Part
The species is Apium graveolens L., a plant that includes leaf celery, stalk celery and celeriac. The part used here is the dried ripe fruit, sold commercially as celery seed. Stalks, leaves and the swollen root of celeriac are not used. The small ribbed fruits hold most of the plant’s aroma, so the seed behaves very differently from the vegetable. Lovage seed is sometimes sold under similar names but comes from a different plant. Celery seed carries a volatile oil rich in limonene and selinene, phthalide compounds that give the typical aroma, and flavone glycosides such as apiin. A water extract keeps mainly the polar share of these constituent families.
