Article Abstract
As a part of our systematic study on genus (Fagaceae), one new triterpene hydrolysable tannin () and two new phenol glucosides ( and ) were isolated from the leaves of (Champ. ex Benth.) Hutch. Compound was identified as a triterpene hexahydroxydiphenoyl (HHDP) ester. This type of compounds has only been isolated from genus. The structures of - were elucidated by the combination of spectroscopic analysis (MS, 1 D and 2 D NMR) and chemical evidence.

The leaves of (Fagaceae) contain characteristic hexahydroxydiphenoyl (HHDP) esters of 28--glucosyl 2α,3β,23,24-tetrahydroxyolean- and urs-12-en-28-oic acids. In this study, uncharacterized substances were detected in the young leaves, which are not observed in the mature leaves. Preliminary HPLC analyses indicated that the substances had dehydro-HHDP (DHHDP) ester groups; however, the esters were unstable and decomposed during extraction.

Based on two-dimensional NMR spectroscopic evidence the structures were determined to be 3,24-di-O-galloyl-2α,3β-23,24-tetrahydroxyolean-12-en-28-oic acid (1) and 3,24-di-O-galloyl- 2α,3β-23,24-tetrahydroxyurs-12-en-28-oic acid (2). The triterpene hexahydroxydiphenoyl esters, which had been found in the leaves, were not detected in the acorns.

Triterpene hexahydroxydiphenoyl (HHDP) esters have only been isolated from Castanopsis species, and the distribution of these esters in nature is of chemotaxonomical interest. In this study, the chemical constituents of the leaves of Castanopsis fissa were examined in detail to identify and isolate potential HHDP esters. Together with 53 known compounds, 3,4-di-O-galloyl-1-O-purpurogallin carbonyl quinic acid (1) and 3,24-(S)-HHDP-2α,3β,23,24-tetrahydroxytaraxastan-28,20β-olide (2) were isolated and their structures were elucidated by spectroscopic and chemical methods.

Five new galloyl and (S)-hexahydroxydiphenyl (HHDP) esters of phenylpropanoid glucosides; 1-O-(E)-coumaroyl-3-galloyl-4,6-(S)-HHDP-beta-D-glucopyranose (21), 1-O-(E)-coumaroyl-3,4,6-trigalloyl-beta-D-glucopyranose (22), 1-O-(E)-caffeoyl-3,4,6-trigalloyl-beta-D-glucopyranose (23), 1-O-(E)-cinnamoyl-3-galloyl-4,6-(S)-HHDP-beta-D-glucopyranose (24), and 1-O-(E)-cinnamoyl-4-galloyl-beta-D-glucopyranose (25), together with twenty known compounds which were identified as four triterpenes (1, 2, 3, 5), one steroid (4), one lignan (6), three phenylpropanoids (7, 8, 14), five phenylpropanoid glucosides (10, 12, 13, 15, 16), five galloyl and HHDP esters of phenylpropanoid glucosides (11, 17-20), and one bischroman (9). Their structures were determined on the basis of 1D and 2D spectroscopic data.
