Coleogyne ramosissima

Purified samples of tannins from bitterbrush (Purshia tri-dentatd) and blackbrush (Coleogyne ramosissima) (both Rosaceae) differ in the acceptability to snowshoe hares (Lepus americanus). The two series of tannins differ in their overall stereochemistry at C-3 and C-4. Because the tannins were highly purified, these differences in stereochemistry of the condensed tannins themselves must be important in these preferences (Clausen et al., 1990 Zucker, 1983).
