SINAGAWA-GARCIA, SR et al. Wereke root (Ibervillea sonorae Greene) descriptive characteristics and biochemical generalities of its aqueous extract. Phyton (B. Aires) [online]. 2015, vol.84, n.2, pp.358-367. ISSN 1851-5657.

A general biochemical description of an aqueous extract obtained from Ibervillea sonorae root was reported; furthermore, a histological description for the root is included. A bromatological analysis was carried out, and it indicated that the study nutritional variables were similar to those reported in other edible tuberous roots including sweet potatoe, mandioca, bean yam and arracacha. For the first time, the presence of an active proteinase at alkaline pH and the inhibitory activity of trypsin were reported for this root. Several medical and bioactive properties have been attributed to the wereke root. Nevertheless, deeper studies are needed to determinate the importance of molecules and their action mechanisms. This work contributed to the knowledge of some biochemical aspects of the wereke root.
