Wistarin (wisteria)

from Wikipedia, the free encyclopedia

Wistarin is a substance that Wilhelm Martin Ottow (1863-1916 ) isolated in 1886 from the bark of the Chinese wisteria ( Wisteria sinensis , wisteria ). It has been described as a crystallizable glycoside that is readily soluble in alcohol and poorly soluble in ether , chloroform, and cold water. The taste of this compound was described as bitter and tart and a melting point of 204 ° C was published.

Although this alleged pure substance, which is occasionally counted among the saponins , could never be assigned an exact structure, it is still partly held responsible in the more recent literature for the symptoms that occur when parts of the wisteria plants are accidentally consumed. Effects similar to tobacco or cytisine are described here.
