Chemical compound
Chebulagic acid is a benzopyran tannin and an antioxidant that has many potential uses in medicine.
It has been found to be immunosuppressive ,[ 1] hepatoprotective ,[ 2] and a potent alpha-glucosidase inhibitor,[ 3] [ 4] a human gut enzyme useful in diabetic studies.
It has been shown to be active against Staphylococcus aureus and Candida albicans .[ 5]
It is found in the plants Terminalia chebula , T. citrina and T. catappa .[ 6]
It is formed from geraniin through a glutathione -mediated conversion.[ 7]
