ABSTRACT
Objective:
To investigate the chemical constituents in the shells of Juglans sigillata.Methods:
The chemical constituents were isolated by silica gel, RP18, Sephadex LH-20, and MCI column chromatography and semi-preparative HPLC and so on. The structures were identified on the basis of spectroscopic analysis and chemical evidence.Results:
Fifteen compounds were isolated and identified in the 70% ethanol extract from the shells of J. sigillata including seven phenolic glycosides tachioside (1), mudanoside A (2), 4-O-β-D-glucopyranosylvanillc acid (3), breynioside A (4), 1-O-vanilloyl-β-D-glucose (5), 6'-O-vanilloyltachioside (6), and 6'-O-vanilloylisotachioside (7); three phenylpropanoide acid glycosides 6-O-feruloyl-D-glucopyranose (8), methyl-4-O-coumaroylquinate (9), and 5-p-cis-coumaroylquinic acid (10); two tetralone glycosides juglanin A (11) and juglanin E (12); one norsesquiterpenes glycoside roseoside (13); one flavone toxifolin (14); and one glucosylated abscisic acid derivate (1'R, 3'R, 5'R, 8'S)-epi-dihydrophaseic acid β-D-glucoside (15).Conclusion:
Except compound 14, the other compounds are isolated from the shells of J. sigillata for the first time. And compounds 1-4, 13, and 15 are reported for the first time from the plants in genus of Juglans L.
