Four prenylated flavonoids compounds 1-4,named sinopodophyllines A-D,and a flavonoid glycoside(compound 13),sinopodophylliside A,together with 19 known compounds(compounds 5-12 and 14-24) were isolated from the fruits...Four prenylated flavonoids compounds 1-4,named sinopodophyllines A-D,and a flavonoid glycoside(compound 13),sinopodophylliside A,together with 19 known compounds(compounds 5-12 and 14-24) were isolated from the fruits of Sinopodophyllum hexandrum.The structures of new compounds were elucidated by extensive spectroscopic analysis,including HRESIMS,1D and 2D NMR.Compounds 1-6,9-11,and 14-17 were tested for their cytotoxicity against human breast-cancer T47 D,MCF-7 and MDA-MB-231 cells in vitro,and compounds 2,5,6,10 and 11 showed significant cytotoxicity(IC50 values < 10 μmol·L^(-1))against T47 D cells.展开更多
目的建立桃儿七的HPLC指纹图谱分析方法,为该药材的鉴别及质量评价提供依据。方法采用Thermo Hy PURITY C18色谱柱(250 mm×4.6 mm,5μm),以甲醇-0.4%磷酸水溶液为流动相,进行梯度洗脱,柱温25℃,体积流量0.8 m L/min,检测波长290 nm...目的建立桃儿七的HPLC指纹图谱分析方法,为该药材的鉴别及质量评价提供依据。方法采用Thermo Hy PURITY C18色谱柱(250 mm×4.6 mm,5μm),以甲醇-0.4%磷酸水溶液为流动相,进行梯度洗脱,柱温25℃,体积流量0.8 m L/min,检测波长290 nm,进样量10μL。采用"中药色谱指纹图谱相似度评价系统"(2004 A)和SPSS 19.0统计软件中的聚类分析对指纹图谱进行相似度分析。结果建立桃儿七的HPLC指纹图谱,确定了17个共有峰,并指认了其中8个共有峰,经相似度评价,19批桃儿七药材指纹图谱与共有模式比较的相似度均在0.9以上,整体相似度较好,聚类结果与相似度评价结果基本一致。结论该研究建立的桃儿七HPLC指纹图谱可为该药材的鉴别及质量评价提供更全面的参考。展开更多
