摘　　要：目的　研究铁刀木的化学成分。方法　利用硅胶柱色谱和薄层色谱分离铁刀木的化学成分 ,通过理化常数测定和波谱分析等鉴定化合物的结构。结果　从铁刀木树干中分离并鉴定了 5个化合物 ,其结构分别鉴定为 :β 谷甾醇 (I) ,蔗糖 (II) ,正二十八醇 (III) ,2 甲基 5 ( 2′ 羟丙基 ) 7 羟基色酮 2′ O β D 吡喃葡糖苷 (IV) ,3 ,3′ ,4,5′ 四羟基二苯乙烯 (V)。结论　化合物II,III,V为首次从该植物中分得 。Aim To study the chemical constituents of the stem of Cassia siamea . Methods The compounds were isolated by chromatography on silica gel, and identified on the basis of spectral analysis. Results Five compounds were isolated and identified as: β sitosterol (I), sucrose (II), n octacosanol (III), 2 methyl 5 (2′ hydroxypropyl) 7 hydroxy chromone 2′ O β D glucopyranoside (IV) and piceatannol (V). Conclusion Compound IV is a new compound. Compounds II,III and V were obtained from this plant for the first time.
