Dianthus japonicus, six new and seven known oleanane-type triterpene saponins were isolated. The structures of the new saponins, named dianthosaponins A-F, were elucidated by means of high resolution mass spectrometry, and extensive inspection of one- and two-dimensional NMR spectroscopic data. A new C-glycosyl flavone, a glycosidic derivative of anthranilic acid amide and a maltol glucoside were also
从石竹的地上部分中,分离出六种新的和七种已知的齐墩果型三萜皂苷。通过高分辨率质谱分析法和一维和二维NMR光谱数据的广泛检查,阐明了新的皂苷(称为双硫皂苷AF)的结构。还分离了新的C-糖基黄酮,邻氨基苯甲酸酰胺的糖苷衍生物和麦芽酚糖苷。
