- Abstract
Fourteen chemical constituents, including 5-hydroxy-4-methoxy-1-tetralone(1), 4,8-dihydroxy-1-tetralone(2), 4,5-dihydroxy-α-tetralone(3), blumenol B(4), dehydrovomifoliol(5), megastigm-5-ene-3,9-diol(6), juglanin B(7), blumenol C(8), loliolide(9), oleracone B(10), syringarsinol(11), pinoresinol(12), methyl 4-hydroxy-3-methoxybenzoate(13), and isovanillic acid(14), were isolated from the dichloromethane fraction of 95% methanol extract of green walnut husks by silica gel and MCI column chromatography, and Pre-HPLC. Their structures were determined by spectroscopic methods, such as NMR, MS and so on. Among them, compounds 1, 4-6, 8-13 were isolated from the green walnut husks for the first time, and compounds 4-6, 8, 10, 12, 13 were isolated from the Juglans genus for the first time. All of isolates were detected their inhibitory activities against HeLa, HGC-27 and Ht-29 cell lines by the MTT assay. The result showed that compounds 2, 3, 7, 9 and 11 exhibited inhibitory activity against the tested cell line. The IC_(50) of 7 were 26.5, 9.0, 25.4 μmol·L~(-1), respectively.
