Etymology: "Catechins" is the plural of "catechin," and the singular goes back to "catechu," the name of an astringent extract once made from the wood of Asian acacia trees and used for tanning leather and dyeing cloth. Chemists took the "-in" ending, a standard suffix for naming organic compounds, and attached it to that older name to label the plant substance they had isolated from catechu. The name records the material it came from rather than any single structure. The word "catechol," a related compound, shares the same ancestry, which is why the two names look so alike. Catechin was named in the same family of chemical terms, so its name carries a trace of a centuries-old trade product into modern laboratory vocabulary.
