【摘要】 目的研究青花椒Zanthoxylum schinifolium生物碱类化学成分及其生物活性。方法采用正相硅胶、Sephadex LH-20、重结晶、半制备HPLC等色谱方法进行分离纯化,通过理化性质及波谱数据鉴定化合物结构,并通过MTS法对化合物进行细胞毒活性筛选。结果从青花椒根部的醋酸乙酯提取物中分离得到9个生物碱,分别鉴定为白藓碱(1)、茵芋碱(2)、青花椒碱(3)、6-甲氧基-呋喃喹诺酮(4)、(+)-(S)-异普拉得斯碱(5)、(+)-(S)-阿瑞罗甫碱(6)、(-)-(S)-日立宁(7)、加锡弥罗果碱(8)、(-)-(S)-丙酮基白屈菜赤碱(9)。结论化合物4为新的天然产物,化合物5～9为首次从该植物中分离得到。其中化合物9能够抑制人支气管上皮细胞的生长,对肿瘤细胞HL-60、SMMC-7721和A-549细胞株具有潜在的细胞毒活性。更多还原

【Abstract】 Objective To study the chemical structure and bioactivity of the alkaloids from Zanthoxylum schinifolium. Methods The alkaloids were isolated and purified by silica gel, Sephadex LH-20 column chromatography, recrystallization, and semi-preparetive HPLC. Their structures were elucidated by physical and spectroscopic analysis. The cytotoxic activity of these compounds were tested by MTS. Results Nine alkaloids were obtained and identified as dictamnine(1), skimmianine(2), schinifoline(3),6-methoxy-furanoquinolone(4),(+)-(S)-isoplatydesmine(5),(+)-(S)-araliopsine(6),(-)-(S)-ribalinine(7),(-)-(S)-edulinine(8), and(-)-(S)-6-acetonyldihydrochelerythrine(9). Conclusion Compound 4 is a new natural product and compounds 5—9 are isolated from this plant for the first time. Compound 9 has potential cytotoxicity towards HL-60, SMMC-7721, and A549.更多还原
