Tara (Caesalpinia spinosa Kuntze), also known as the thorn cloud, is a species of evergreen shrubs of the sapwood family, growing in the northwest of South America, rich in Peru,
Ecuador, mainly distributed in the Andes Mountains near the Pacific in the valleys and valleys.
A natural compound isolated from Tara pods. Galloyl and polygallyl esters composed of quinic acid were associated with an average of 4-5 galloyl groups per quinic acid.
The chemical structure [13] of taltannin is a polyploid ester with 3,4, 5-tri-0-quinoyl-quinic acid as the "core", that is, one quinic acid combined with 4-5 gallic groups, with an average molecular formula of C35H28O32. The gallic group structure in the tara tannin molecule is the same as that in gallnut tannin.
