Methylgallic acid-O-sulphate
Methylgallic acid-O-sulphate is a conjugate of methylgallic acid and sulphate. methylgallic acid is a methyl ester of gallic acid. Gallic acid is a trihydroxybenzoic acid, a type of phenolic acid, a type of organic acid, also known as 3,4,5-trihydroxybenzoic acid, found in gallnuts, sumac, witch hazel, tea leaves, oak bark, and other plants. The chemical formula is C6H2(OH)3COOH. Gallic acid is found both free and as part of hydrolyzable tannins. (Wikipedia)

Arctinol
Arctinol b is a member of the class of compounds known as bi- and oligothiophenes. Bi- and oligothiophenes are organic compounds containing two or more linked thiophene rings. Thiophene is a five-member aromatic ring with one sulfur and four carbon atoms. Arctinol b is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Arctinol b can be found in burdock, which makes arctinol b a potential biomarker for the consumption of this food product.
