説明
The chirality of the nonahydroxytriphenoyl group in castalagin (1) and vescalagin (2) was determined to be in the S, S-series on the basis of circular dichroism analysis. In addition, a new ellagitannin (4) has been isolated from the leaves of Eugenia grandis (Myrtaceae), and the structure was established to be 1-Ο-galloyl castalagin on the basis of chemical and spectroscopic evidence.
