OBJECTIVE
To study hydrolysable tannin constituents of the seed of Juglans regia.
METHODS
The chemical constituents were isolated by Diaion HP-20, Toyopaerl HW-40 and MCI gel CHP-20P column chromatogramphy and identified by physicochemical identification and spectral data.
RESULTS
Six compounds obtained from the 70% ethanol extract were identified as 1, 2, 3, 4, 6-penta-O-galloyl-3-D-glucose (1), rugosin C (2), 1, 2, 3, 6-tetra-O-galloyl-3-D-glugose (3), tellimagrandin II (4), casuarictin (5), 1-degalloylrugosin F (6).
CONCLUSIONS
All compouds were isolated from the seeds of J. regia for the first time.
