Three new ellagitannins, casuariin (5), stachyurin (6) and strictinin (7) have been isolated from Casuarina stricta, and their structures elucidated. Of these, 5 and 6 were found to be C-glucosidic tannins. All of the ellagitannins (1-7) isolated from C. stricta have been found also in Stachyurus praecox.
