Two new taraxastane-type triterpenoids from the fruit of Cicuta virosa L.var latisecta Celak

Two new taraxastane-type triterpenoids,20-taraxastene-3β,12β,16β-triol 1 and 3β-feruloyloxy-20-taraxastene-16β,28-diol 2, were isolated from the fruit of Cicuta virosa L.var latisecta Celak.There structures were elucidated by ESI-MS,1D- and 2D-NMR spectroscopic methods.

兴化莳萝的化学研究

目的利用色谱和光谱方法研究兴化莳萝地上部分的化学成分。方法通过乙醇-水梯度提取,石油醚、乙酸乙酯、正丁醇萃取,硅胶、凝胶、反相柱层析和薄层色谱等技术分离出纯化合物,通过核磁共振氢谱、核磁共振碳谱、质谱等光谱技术分析化合物结构。结果从石油醚及乙酸乙酯部位分离鉴定出四个化合物,分别为3-羟基-9(11),12-齐墩果烯(I)、邻苯二甲酸二异辛酯(II)、β-谷甾醇(III)及其苷β-胡萝卜苷(IV)。结论明确了兴化莳萝地上部分的化学成分,为其进一步研究开发利用提供实验依据。
