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。
Aim To study the chemical constituents of the aerial parts of Xinghua dill by using chromatographic and spectral methods. Methods The pure compounds were separated by ethanol-water gradient extraction, petroleum ether, ethyl acetate, n-butanol, silica gel, gel, reversed phase column chromatography and thin layer chromatography. The structures were characterized by 1H- Spectral, mass spectrometry and other spectroscopic techniques for the analysis of compound structures. Results Four compounds were isolated and identified from petroleum ether and ethyl acetate fractions as 3-hydroxy-9 (11), 12-oleanophenone (I), diisooctyl phthalate (II) - sitosterol (III) and its glycosides β-daucosterol (IV). Conclusion The chemical composition of aboveground parts of Xinghua dill was clarified, which provided the experimental basis for its further research and development.
