Abstract

Condensed tannins, mainly comprised of flavan-3-ol (catechin and epicatechin) units, are one of the phenolic compounds in wood with molecular weights between 500–3000 as shown in Figure 1 [1, 2]. The condensed tannins have been traditionally utilized as the agents for converting animal hides to leather (tanning). Recently, the tannins have been also used as an adhesive for wood materials, coagulant and coating material, and expected to be utilized as pharmaceutical products because of their biological activities [3].
