Summary

1. A new glycoside neorobinin has been isolated from the seeds ofCheiranthus allionii. On the basis of the results of chemical and spectroscopic investigations, the structure of kaempferol 7-α-L-rhamnofuranoside-3-(β-D-galactofuranosyl-6-β-L-rhamnofuranoside) has been proposed for it.

2. On partial hydrolysis, neorobinin is split into a series of intermediate substances, the following of which have been isolated and characterized: kaempferol 7-α-L-rhamnofuranoside (rhamnorobin), kaempferol 3-β-D-galactofuranoside (galactorobin), and kaempferol 3-(β-D-galactofuranosyl-6-β-L-rhamnofuranoside) (biorobin).
