| 摘 要： | 目的建立3种石斛药材的氢核磁共振谱(1HNMR)特征图谱。方法首先采用溶剂萃取法或硅胶色谱分离法获得3种石斛(束花石斛D.chrysanthum Wall.,铁皮石斛D.candidum Wall.ex Lindl和金钗石斛D.nobile Lindl.)的特征提取物及其主要成分,然后利用FT-1HNMR(300MHz)技术测定得1HNMR特征图谱并对特征信号进行归属。结果束花石斛、金钗石斛的SCE-B和铁皮石斛的SCEA特征提取物的1HNMR特征图谱可作为该药材基源鉴定的相对标准图谱。结论建立的1HNMR特征图谱方法在鉴别中药石斛上具有指导意义。

| Abstract: | Objective To analyse the 1HNMR fingerprints of 3 Dendrobium species.Methods Solvent extraction and silica gel chromatography were used to separate the chemical constituents of SCE A or B from the stem of 3 Dendrobium species. The characteristic signals of the 1HNMR finger print were ananlysed after determining the structures of the compounds isolated from SCE A or B. Results 1HNMR characteristic spectrum of the samples of D. chrysanthum Wall., D. candidum Wall.ex Lindl and D.nobile Lindl. collected from different regions showed highly characteristic features and reproducibility, respectively. Conclusion The 1HNMR spectrum of SCE A or B from the stem of 3 Dendrobium species can be utilized for its original authentication. |
