Our previous study reported the isolation andidentification of five quinoline alkaloids . In this continuing study on the chemcial constituentsof Zanthoxylum dissitum Hemsley, a phenylalanine derivative was obtained .展开更多
目的:对小蓟的化学成分进行研究。方法:运用硅胶柱层析、Sephadex LH-20柱层析等手段进行分离,运用UV、1HNMR、13CNMR、MS等波谱方法进行结构鉴定。结果:共分离鉴定了6个化合物,分别为乙酸橙酰胺(auran-tiam ide acetate,1),loliolide(...目的:对小蓟的化学成分进行研究。方法:运用硅胶柱层析、Sephadex LH-20柱层析等手段进行分离,运用UV、1HNMR、13CNMR、MS等波谱方法进行结构鉴定。结果:共分离鉴定了6个化合物,分别为乙酸橙酰胺(auran-tiam ide acetate,1),loliolide(2),刺槐素(acacetin,3),蒙花苷(linarin,4),洋芹素-7-O-β-D-葡萄糖醛酸丁酯(ap igen in-7-O-β-D-butylglucuron ide,5),β-胡萝卜苷(β-daucosterol,6)。结论:化合物1为首次从蓟属植物中分离得到,化合物2、5、6首次从小蓟中分离得到。展开更多
