从满山红(Rhododendron dauricum L.)叶中经硅胶或氧化铝柱层析分离,又得到八种结晶成分,根据光谱分析、衍生物制备及其物理化学常数的测定,其中四种成分分别鉴定为莨菪亭、伞形酮、梫木毒素及氢醌,其他四种成分因得量少,药理和鉴定工作尚未进行。 Eight crystalline components were obtained from the leaves of Rhododendron dauricum L. by silica gel or alumina column chromatography. According to spectral analysis, preparation of derivatives, and determination of their physical and chemical constants, four components were identified. For the palatine, umbelliferone, eucalyptus toxin, and hydroquinone, the other four components are of limited use, and pharmacology and identification work has not yet been carried out.
