| description | A new hydrolysable tannin, ethyl castavaloninate (
1
), was isolated from the seeds of
Quercus wutaishanica,
along with nine known compounds, γ-tocopherol (
2
), ethyl brevifolincarboxylate (
3
), brevifolin (
4
), (–)-7,7′-dioxodihydroguaiaretic acid (
5
), (–)-pinoresinol (
6
), (–)-dihydrodehydrodiconiferyl alcohol (
7
), (+)-isolariciresinol (
8
), decarboxylated ellagic acid (
9
), and ellagic acid 4-O-xylopyranoside (
10
). The structure of
1
was determined by spectroscopic methods, including NMR, HR-ESI-MS, and IR spectra. This is the first report of compounds
2–10
from the genus
Quercus. |
