Certain flavonoids are used by plants to protect them from invasion by parasites. For example, poplar (Populus spp.) cultivars produce a chemical barrier to parasitization by mistletoe (Viscum album).Resistant poplar cultivars were significantly higher in flavonols and flavones compared to susceptible cultivars. Likewise, in Streblus asper the bark and wood of trees that are resistant to the parasite Cuscuta reflexa hold higher levels of flavonoids, as well as steroids and alkaloids. [Pg.422]

When beavers first colonize a site they begin by harvesting the most palatable species, such as aspen (Populus spp.) or willow (Salix spp.). Over time, they change the vegetation by their selection of trees for food and construction of dams and lodges. Eventually, often only the least preferred conifers are left, and the beavers move to a new area until some of the depleted vegetation has regenerated. Beavers move back in, and the cycle repeats.

The simplest phenolic n-glucoside is arbutin (p-hydroxyphenyl /3-d-glucopyranoside), which occurs in a number of plant species, including the pear Pyrus communis. Arbutin is usually accompanied in plant tissues by methylarbutin (p-methoxyphenyl S-D-glucopyranoside)Salix and Populus spp. contain the D-glucoside salicin, o-(hydroxymethyl)-phenyl /S-D-glucopyranoside, and certain species of poplar contain also a...

The glycosides of salicyl and gentisyl alcohols in Salix spp. and Populus spp., genera of the Salicaceae family, have been extensively studied by Pearl et al. (124-130) and Thieme et al. (168-171) (see summary and references in ref. 123). Salicin (14), the glucoside of salicyl alcohol, occurs characteristically in this family of plants. This compound is found in the bark of all species in the family, but often in small amounts. Another characteristic compound of the many salicin-related compounds occurring in most Salix species is salicortin (15), in which the... [Pg.371]
