Brassica rapa Root Identity & Plant Part
The botanical entity is Brassica rapa L., a biennial of the Brassicaceae with a swollen storage root at the base of the stem. The part used is the root, which is round to flat, white-fleshed and often purple at the top. Leaves, flowers and seeds are not part of this ingredient. The species is very diverse, and turnip is only one of its forms.
Brassica rapa also includes Chinese cabbage and bok choy, and the closely related swede is a different species, Brassica napus. The turnip root carries glucosinolates, phenolic acids, flavonoids, sugars and pectin, named here as families only. Turnip extract holds the water-soluble share of these.
