[Structure of silandrin and silymonin, two new flavanolignans from a white blooming Silybum marianum variety].
The structures of two flavanolignans, (-) silandrin and (+) silymonin, from a white flowering variety of Silybum marianum, have been elucidated as 3-desoxy-isosilybin and 3-desoxy-silydianin partly by spectroscopic investigations, partly by chemical transformation into other derivatives and their partial synthesis. In addition 5,7-dihydroxy-chromone has been isolated as a new compound.
