Article abstract of DOI:10.1039/P19830001765

Three novel C-glucosidic ellagitannins, casuarinin, casauriin, and stachyurin, and two additional new ellagitannins, casuarictin and strictinin, were isolated from the leaves of Casuarina stricta, and their structures elucidated on the basis of chemical and spectral evidence.Pedunculagin and tellimagrandin I were also isolated, and the structure having (S)-4,4',5,5',6,6'-hexahydroxydiphenoyl groups was established for pedunculagin.These seven ellagitannins isolated from C. stricta have been found also in Stachyurus praecox.
