Monoterpene glycosides isolated from Fadogia agrestis

We report the isolation and structural elucidation of six monoterpene glycosides from Fadogia agrestis, a shrub used in traditional african medicine. The compounds are all derivatives of 2,6-dimethyl-2(E),6(Z)-octadiene-1,8-diol. In addition, three of them contain the acyl group B. The glycosides are derivatives of rhamnose and glucose.
