Derris urucu

Nitrogen-containing sugar analogs have recently been described fi-om several Fabaceae species. One of them, 2-5-dihydroxymethyl-3,4-hydroxypyrrolidine (DMDP), was first isolated form leaves and roots of Derris elliptica (10). These sugar mimics were shown to be powerfid glucosidadse inhibitors (11). DMDP acts as an antifeedant for locusts and is toxic for certain caterpillars and beetles. It was isolated in our laboratory fi-om the roots of Derris urucu (Mathias, L. Parente, J. P., unpublished data.)...

Rotenone (Figure 56-1) is obtained from Derris elliptica, D mallaccensis, Lonchocarpus utilis, and L urucu. The oral ingestion of rotenone produces gastrointestinal irritation. Conjunctivitis, dermatitis, pharyngitis, and rhinitis can also occur. Treatment is symptomatic. 

Rotenone is the principal active insecticidal constituent of derris, the dried rhizome and roots of Derris elliptica, D. malaccensis (Leguminosae) and other species of Derris, and of lonchocarpus, the dried root of Lonchocarpus utilis, L. urucu and other species of Lonchocarpus (Leguminosae).
