The aqueous extract of galls from Terminalia chebula Retz. (Combretaceae) was fractionated on Diaion and refractionated on octadecyl silica column. Six phenolic compounds were isolated and identified as gallic acid (1), punicalagin (2), isoterchebulin (3), 1,3,6-tri-O-galloyl-β-D-glucopyranose (4), chebulagic acid (5) and chebulinic acid (6). All of the compounds showed stronger 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and melanin inhibitory activities than ascorbic acid… 

In vivo Toxicity Studies on Gall Extracts of Terminalia chebula (Gaertn.) Retz. (Combretaceae)

There was a strong correlation of higher toxic effect with that of high total phenolic and flavonoids content in the ethanolic leaf gall extracts of T. chebula, which would serve as an index for formulation of drugs for treatment of various diseases.

Antioxidant activities of leaf galls extracts of Terminalia chebula (Gaertn.) Retz. (Combretaceae).

The results of this study confirm the folklore use of T. chebula leaves gall extracts as a natural antioxidant and justify its ethnobotanical use, as the higher content of both total phenolics and flavonoids were found in the ethanolic extract, so the significantly high antioxidant activity can be positively correlated to the high content of total polyphenols/flavonoids of the ethanol extract.

Biological Activities of Phenolic Compounds and Triterpenoids from the Galls of Terminalia chebula
