從百合科植物韭 Allium tuberosum Rottler的種子中分離并鑒定了 5個含氮化合物: N -順式 -阿魏?；?-3-甲基多巴胺 (Ⅰ),N-反式 -阿魏酰基 -3-甲基多巴胺 (Ⅱ),N-反式 -香豆酰酪胺 (Ⅲ), 3-甲酰吲哚 (Ⅳ)和 3-吡啶羥酸(Ⅴ),其中 Ⅰ 為新化合物,命名為韭子堿甲 ( tube rosine A),其它化合物均為首次從該植物中分得。

Five compounds were isolated from the seed of Allium tuberosum Rottl.ex Spreng..On the basis of chemical and spectroscopic analysis,they were identified as:N - cis-feruloyl-3-methyldopamine (Ⅰ),(named tuberosine A),N- trans-feruloyl-3-methyldopamine (Ⅱ),N - trans-coumaroyl tyramine (Ⅲ),3-formylindole (Ⅳ) and 3-pyridine carboxylic acid (Ⅴ).Among them,Ⅰ was a new compound,Ⅱ ～ Ⅴ were obtained from this plant for the first time.
