Papyriferic acid

Triterpenes (C30) are common in birches, especially in bark. Papyriferic acid from paper birch, Betula resinifera, is a feeding deferent for snowshoe hares, Lepus americanus Big. 11.5) (Reichardt etal, 1985). [Pg.277]

Particularly valuable and/or vulnerable parts are protected best. Because of their size and seasonal changes, trees provide instructive examples. In green alder, Alnus crispa, defense compounds, such as pinosylvin, pinosylvin methyl ether and papyriferic acid, are concentrated in buds (2.6% of dry weight) and catkins (1.7%), and least abundant in the internodes (0.05%). Snowshoe hares, L. americanus, reject buds and catkins, while they eat second-year internodes (Bryant etu/., 1983 Clausen eta/., 1986). [Pg.300]
