ABSTRACT:
A set of chiral stationary phases is based on yohimbine and its derivatives. One set of chiral stationary phases is based on a coating of yohimbine and yohimbine derivatives, and another set is based on covalent linkage of the chiral organic material to the underlying support. Both sets are effective in resolving enantiomeric mixtures.
