Methods Manykinds of chromatogra-phy methods were used in the isolation procedure, while the structures ofisolated compounds were determined on the aids of NMR and MS spectral analysis. Result Three newcompounds, together with 14 known compounds, were isolated form the 80% ethanolic extract of itsstems. Conclusion The three new compounds, opuntioside Ⅰ (2), 4-ethoxyl-6-hydroxymethyl-α-pyrone(3) and kaempferol 7-O-β-D-glucopyranosyl (1→4)-β-D-glucopyranoside (4), were characterized.展开更多
目的 :研究南葶苈子中槲皮素 3 O β D 葡萄糖 7 O β D 龙胆双糖苷的含量测定方法 ,建立南葶苈子药材质量标准。方法 :采用反相高效液相色谱法 ,以自制标准品作对照 ,对南葶苈子药材中主要有效成分槲皮素 3 O β D 葡萄糖 7 O β D...目的 :研究南葶苈子中槲皮素 3 O β D 葡萄糖 7 O β D 龙胆双糖苷的含量测定方法 ,建立南葶苈子药材质量标准。方法 :采用反相高效液相色谱法 ,以自制标准品作对照 ,对南葶苈子药材中主要有效成分槲皮素 3 O β D 葡萄糖 7 O β D 龙胆双糖苷进行了含量测定。 结果 :回收率为 99.78% ,RSD为 2 .4 %。结论 :该方法可用于南葶苈子药材的质量控制。展开更多
