Vanilloyl glucose
Vanilloyl glucose is a member of the class of compounds known as hydrolyzable tannins. Hydrolyzable tannins are tannins with a structure characterized by either of the following models. In model 1, the structure contains galloyl units (in some cases, shikimic acid units) are linked to diverse polyol carbohydrate-, catechin-, or triterpenoid units. In model 2, contains at least two galloyl units C-C coupled to each other, and do not contain a glycosidically linked catechin unit. Vanilloyl glucose is soluble (in water) and a very weakly acidic compound (based on its pKa). Vanilloyl glucose can be found in a number of food items such as orange bell pepper, yellow bell pepper, pepper (c. annuum), and red bell pepper, which makes vanilloyl glucose a potential biomarker for the consumption of these food products.

Vanillic acid 4-beta-D-glucoside
Vanillic acid 4-beta-d-glucoside, also known as vanillate 4-beta-D-glucoside, is a member of the class of compounds known as hydrolyzable tannins. Hydrolyzable tannins are tannins with a structure characterized by either of the following models. In model 1, the structure contains galloyl units (in some cases, shikimic acid units) are linked to diverse polyol carbohydrate-, catechin-, or triterpenoid units.

Orsellinic acid 2-O-beta-D-glucoside
Orsellinic acid 2-o-beta-d-glucoside is a member of the class of compounds known as phenolic glycosides. Phenolic glycosides are organic compounds containing a phenolic structure attached to a glycosyl moiety. Some examples of phenolic structures include lignans, and flavonoids. Among the sugar units found in natural glycosides are D-glucose, L-Fructose, and L rhamnose. Orsellinic acid 2-o-beta-d-glucoside is soluble (in water) and a weakly acidic compound (based on its pKa). Orsellinic acid 2-o-beta-d-glucoside can be found in cloves, which makes orsellinic acid 2-o-beta-d-glucoside a potential biomarker for the consumption of this food product.
