Tamarix aphylla galls containing 47.94 % tannins, belonging mainly to the hydrolysable class were subjected to both qualitative and quantitative tannin analyses. The free–resinous ground meal was successively extracted with ethyl acetate, methanol and water. Free and combined sugars were separated and identified. The ether–soluble fraction of the ethyl acetate extract, subjected to adsorption column chromatography, proved to contain gallic acid, ellagic acid, dehydrodigallic acid, and dihydrojuglone–5–glucoside, together with other polyphenolic components.
