A new ellagitannin, named liquidambin, which could be biogenetically closely correlated with casuarinin and pedunculagin, has been isolated from the leaves of Liquidambar formosana. Its structure was determined as 5-O-galloyl-2,3,4,6-di-O-(S)-hexahydroxydiphenoyl-d-glucose. The structural equilibration due to hydration of the aldehyde group of the glucose core in this tannin was shown from its 1H and 13C NMR spectra.
