战骨是马鞭草科豆腐柴属植物黄毛豆腐柴(Premna fulve Craib),药用其茎。临床治疗肥大性脊椎炎、风湿性关节炎、肩周炎、坐骨神经痛等有良好疗效。但其化学成分至今尚未见报道。用战骨的乙醇提取物经硅胶柱层分离等处理,得到7个单体成分,定名为晶Ⅰ、Ⅱa、Ⅱb、Ⅲ、Ⅳ、Ⅴ和Ⅵ。经用光谱解析和化学方法,确定其中4个成分的化学结构。即Ⅱa为表木栓醇,Ⅱb为木栓酮、Ⅲ为硬
The bone of war is the genus Premna fulve Craib of the genus Verbena, which is used medicinally for its stems. Clinical treatment of hypertrophic spondylitis, rheumatoid arthritis, frozen shoulder, sciatica, etc. have a good effect. However, its chemical composition has not yet been reported. The ethanol extract of the war bone was subjected to silica gel column separation and the like to obtain 7 monomer components designated as crystal I, IIa, IIb, III, IV, V and VI. The chemical structure of the four components was determined by spectral analysis and chemical methods. That is, IIa is epi-xylol, IIb is xanthone, and III is hard.
