A new natural product, 3,4,8-trihydroxybenzopyranopyran-6,9-dione was isolated from the aqueous ethanolic gall extract of Tamarix aphylla (Tamaricaceae) along with the known phenolics, monodecarboxyellagic acid and brevifolin carboxylic acid as well. The structures have been established by ESI-MS, ¹H and ¹³C NMR spectral analysis. Antiinflammatory, antipyretic and ulcerogenic activities determination for both plant (Tamarix aphylla and Phragmites australis) were carried out on aq. ethanolic of extracts.
