Objective To investigate the chemical constituents in the green husk of Juglans sigillate. Methods The chemical constituents were isolated by silica gel, RP-18, MCI column chromatographies and so on. The structures were identified on the basis of spectroscopic analysis (MS, 13C-NMR, 1H-NMR). Results Eleven compounds were isolated from the extract of green husk of J. sigillate. And their structures were characterized as: sinapaldehyde (1), (Z)-10-eicosenoic acid (2), 5α,8α-epidioxyergosta-6,22E-diene-3β-ol (3), 5,8-dihydroxy-4-methoxy-α-tetralone (4), regiolone (5), 4,5-dihydroxy-α-tetralone (6), 4,5,8-trihydroxy-α-tetralone (7), 5-hydroxy-4-methoxy-α-tetralone (8), 5-hydroxy-2-methoxy-1,4-naphthoquinone (9), naringenin (10), and β-sitosterol (11). Conclusion Compounds 1—2 are isolated from the plants of Juglans Linn. for the first time.
