Abstract: A new amide, the dimer of desmethoxypiplartine(1 ), to gether with four known comp-ounds, (Z) -l2 -octadecenic-α- glycerol mon oester(2), piperine (3), β- sitosterol(4), daucosterol(5),were isloated from Piper longum L. The structures were determined by spectra data and comparision with authentic samples.

Key words: Piper

摘要: 从荜拔(Piper Iongum L.)地上部分乙醇提取物中分得 5个化合物,经波谱分析确定其结构分别为:(α,β,α,β)-1,3-双(3,4-二甲氧基苯基)-2,4-双[1-(2-羰基-5,6-二氢吡啶)-甲酰基]环丁烷(1)(Z)-12-十八碳烯酸-α-甘油单酯(2),胡椒碱(3),β-谷甾醇(4),胡萝卜甙(5)。其中(1)是新化合物,(2)为首次从该植物获得。
