A new cerebrogalactoside, Juglans cerebroside A (1), together with five known compounds, quercetin-3-O-β-D-galactopyranoside (2), myricetin-3-O-β-D-galactopyranoside (3), 2''E-quercetin-3-O-β-D- (6''''-O-[3''-(4'''-hydroxyphenyl) propylene acyl]) glucopyranoside (4), gallic acid (5), and 2-methyl-1-hexadecanol (6) were isolated from the leaves of Juglans mandshurica Maxim. The structures of these compounds were determined by 1D, 2D NMR, and MS techniques.

Preliminary studies of in vitro cytostatic activity on less polar fraction of the MeOH extract of the plant Euphorbia nicaeensis All., carried out on KB cells, have evinced a relatively low ability of extract to inhibit cell growth. Successive, five glucocerebrosides were isolated from the cerebroside molecular species obtained from this extract using normal and reversed phase column 'flash-chromatography'. The structures of these cerebrosides were determined on the basis of chemical and spectroscopic evidences. Mass spectrometry of dimethyl disulfide derivatives was useful for the determination of the double-bond positions in the long-chain bases.
