Curcumin Derived from Turmeric (Curcuma longa): a Spice for All Seasons
Curcuma longa or turmeric is a tropical plant native to southern and southeastern tropical Asia. A perennial herb belonging to the ginger family, turmeric measures up to 1 m high with a short stem and tufted leaves (Figure 23.1A). The parts used are the rhizomes. Perhaps the most active component in turmeric is curcumin, which may make up 2 to 5% of the total spice in turmeric (Figure 23.1B).
