Chemical constituents from the linseed meal

Ten compounds were isolated from the 70% ethanol extract of linseed meal (Linum usitatissimum L) through a combination of various chromatographic techniques, including silica gel, macroporous adsorbent resin, Sephadex LH-20, and preparative HPLC.  On the basis of spectroscopic data analysis, they were elucidated as 1-methylethyl-2-O-β-D-glucopyranosyl-(1''→6')-β-D-glucopyanoside (1), linustatin (2), neolinustatin (3), lotaustralin (4), linamarin (5), deoxyguanosine (6), deoxyadenosine (7), (+)-pinoresinol-4'-O-β-D-glucopyranoside (8), 4-O-β-D-glucopyranosylvanillyl alcohol (9) and tachioside (10), separately.  Among them, compound 1 is a new compound, and compounds 6, 8 and 10 were isolated from the linseed meal for the first time.
