Two new glycosides including an alcohol glycoside and a phenolic glycoside: hexyl-1-O-α-d-arabinofuranosyl-(1 → 6)-β-d-glucopyranoside (1), 4-hydroxypropiophenone-4-O-β-d-glucopyranosyl(1 → 6)-β-d-glucopyranoside(2), along with six known naphthalenyl glucosides (38) were isolated from green walnut husks of Juglans mandshurica, and their structures were elucidated on the basis of spectroscopic studies. All compounds were evaluated for their inhibitory effects on tumour cells (BGC-823, HepG-2, MCF-7). The results showed that new compounds 1 and 2 had superior inhibitory activity in comparison with other naphthalenyl glucosides.
