Abstract

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-beta-D-glucopyranosyl-(1" --> 6')-beta-D-glucopyanoside (1), linustatin (2), neolinustatin (3), lotaustralin (4), linamarin (5), deoxyguanosine (6), deoxyadenosine (7), (+)-pinoresinol-4'-O-beta-D-glucopyranoside (8), 4-O-beta-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.

摘要

通过硅胶、大孔吸附树脂、葡聚糖凝胶LH - 20和制备型高效液相色谱等多种色谱技术相结合，从亚麻籽粕（Linum usitatissimum L）的70%乙醇提取物中分离出10种化合物。基于光谱数据分析，它们分别被鉴定为1 - 甲基乙基 - 2 - O - β - D - 吡喃葡萄糖基 - (1" --> 6') - β - D - 吡喃葡萄糖苷（1）、亚麻苦苷（2）、新亚麻苦苷（3）、百脉根苷（4）、亚麻氰苷（5）、脱氧鸟苷（6）、脱氧腺苷（7）、(+) - 松脂醇 - 4'- O - β - D - 吡喃葡萄糖苷（8）、4 - O - β - D - 吡喃葡萄糖基香草醇（9）和龙胆碱（10）。其中，化合物1是一种新化合物，化合物6、8和10首次从亚麻籽粕中分离得到。
