从铁箍散的茎和根中分得六个化合物.其中一个是新化合物,命名为表恩施辛(1,epienshicine),在体外具有抗癌活性.其结构由光谱分析和化学转化确定为1-氧代-2R,3S-二甲基-4R-(3-甲氧基-4-羟基苯)-6,7-次甲二氧基四氢萘.其余五个为已知物,分别鉴定为恩施辛(2,enshicine),isoschizandrolic acid(3),去氧五味子素,β-谷甾醇和硬脂酸,其中3系首次自天然界获得 Six compounds were isolated from stems and roots of iron hoop powder. One of them was a new compound named Epiepshicine which had anticancer activity in vitro. Its structure was confirmed by spectral analysis and chemical transformation. -oxo-2R,3S-dimethyl-4R-(3-methoxy-4-hydroxybenzene)-6,7-methylenedioxytetralin. The remaining five are known and identified. Enshicine (2, enshicine), isoschizandrolic acid (3), deoxyschisin, β-sitosterol and stearic acid, of which the 3 series were first obtained from the natural world
