(+)-Catechin, epicatechin and epigallocatechin are important inducible defensive compounds against Ectropis grisescens in tea plants.

Plant, Cell and Environment, 2021
The tea plant, Camellia sinensis (L.) O. Kuntze, is an economically important, perennial woody plant rich in catechins. Although catechins have been reported to play an important role in plant defenses against microbes, their roles in the defense of tea ...

Association of (+)-catechin and catechin-(4α→ 8)-catechin with oligopeptides

Chem. Commun., 1996
NOE studies on the complexation of (poly) flavanoids with peptides containing proline residues in aqueous solutions reveal site specific approach directed by hydrophobic interaction of the aromatic rings of catechin and its dimer, catechin-(4α→ 8)-catechin, to conformationally accessible regions of peptides without strong preference for interaction ...
