"Cynomorium coccineum " var . " coccineum " from Sardinia was found to contain gallic acid and cyanidin-3-O-glucoside as the main constituents.
It engages in allelopathy, the release of chemicals including gallic acid and hydroquinone, to prevent other plants from growing directly next to it.
Hydrolyzable tannins break down on hydrolysis to give gallic acid and glucose or ellagic acid and glucose, known as gallotannins and ellagitannins respectively.
In this case 100 mL ethanol is used and one drop of sulfuric acid is used per drop of gallic acid in ethanol.
Gallic acid released by Phragmites is degraded by ultraviolet light to produce mesoxalic acid, effectively hitting susceptible plants and seedlings with two harmful toxins.

The hydroxyl groups of the carbohydrate are partially or totally esterified with phenolic groups such as gallic acid in gallotannins or ellagic acid in ellagitannins.
Phytotoxic allelochemicals, such as mimosine and certain phenolic compounds, including p-hydroxycinnamic acid, protocatechuic acid, and gallic acid, have been identified in the leaves of the species.
