Tannins - US Forest Service
网页Tannins are found commonly in the bark of trees, wood, leaves, buds, stems, fruits, seeds, roots, and plant galls. In all of these plant structures, tannins help to protect the individual plant species.
Tannin - Wikipedia
网页The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant growth. [1] The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. [ 2 ]

Diverse Ecological Roles of Plant Tannins: Plant Defense and Beyond
网页Since tannins are found at high concentrations in forest plants, they can have far-reaching ecological effects. This chapter provides an overview of their diverse functions in defense against leaf-eating herbivores and pathogens, in modulating dispersal in fruits and seeds, and as regulators of nutrient cycling and abiotic stress tolerance.
Tannins — Their Place in Plant Metabolism | SpringerLink
网页Calculations show that the cost of diversion of biochemical energy of living plants into tannins is high compared to energy requirements for the structural cell wall polysaccharides. Hence, in many high-tannin-content plants, tannin synthesis contributes significantly to captured photosynthetic energy usage.
