Capparis sola

According to Krukoff and Smith (102), the Yagua (Java) considered the bark and sapwood from the stems of Capparis sola J.F. McBr. (Cappari-daceae) to form a very important constituent of their curare. 

Folkers (281) and Folkers and Unna (136) demonstrated that alkaloid-containing extracts from stem-bark material of Capparis sola J.F. MacBr. (Capparidaceae) collected by Krukoff had distinct paralyzing activity in the frog. The nature of the substances responsible for the activity is not known. It is not likely to derive from the simple quaternary ammonium bases, such as L-stachydrine and L-3-hydroxystachydrine, that have been isolated from or detected in several Capparis species (469). A reinvestigation would be of interest.
