No. The $250 test covers identity, purity and quantity by HPLC-UV measurement of chebulagic acid and chebulinic acid, with LC-MS identity. Full testing to the USP Terminalia Chebula Fruit monograph is available and quoted.
Total tannin methods respond to many polyphenols. Measuring chebulagic and chebulinic acid by HPLC gives a result specific to haritaki tannins.
Hydrolyzable tannins slowly hydrolyze to gallic acid and ellagic acid, especially with moisture. A high gallic acid level relative to the tannins can point to aged material.
Triphala blends haritaki with amla and bibhitaki, which share some tannins. Chebulagic and chebulinic acids can be measured, but assigning them to one fruit in a blend has limits.
