Structural revision of bryonoside and structure elucidation of minor saponins from Bryonia dioica.
The structure of bryonoside, which has previously been isolated from the roots of Bryonia dioica, has been revised. In addition, three new cucurbitacin saponins, named brydioside A, B and C have also been obtained. Their structures were established on the basis of spectral and chemical evidence.
