Streblus

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.

Among these plants, G. pentaphylla, D. gangeticum, E alsinoides are used by wild herbivores like the sambar and chital. Elephants were seen to feed on the roots of Calamus spp and bark of Streblus asper. The Nilgiri langur was seen to feed on the leaves of S. asper, while lion tailed macaques fed on the leaves of Mesua ferrea.
