摘　　要：【目的】研究水稻稻壳的化学成分及其除草活性。【方法】用柱层析的方法和现代波谱技术手段对水稻稻壳乙醇提取物的氯仿萃取部分化学成分进行分离和结构鉴定。【结果】分离鉴定了7种化合物,分别为苜蓿素-7-O-新橙皮糖苷(1)、麦黄酮(2)、stigmast-4-en-6β-ol-3-one(3)、stigmast-4,22E-dien-6α-ol-3-one(4)、3-羟基-4-甲氧基苯乙酮(5)、4-羟基-3-甲氧基肉桂醛(6)和tachioside(7)。【结论】化合物1、3~7为首次从水稻中分离得到,化合物1和化合物2在50μg/mL时能显著抑制稗草的生长。[Purpose]To study the chemical constituents of rice hulls and their herbicidal activities.[Methods]The chemical components from chloroform fractions of ethanol extract of rice hulls were isolated and identified by the methods of column chromatography and modern spectroscopic in this paper.[Results]Seven compounds were isolated and identified as tricin-7-O-neohesperidoside(1),tricin(2),stigmast-4-en-6β-ol-3-one(3),stigmast-4,22E-dien-6α-ol-3-one(4),1-(3-hydroxy-4-nethoxyphenyl)ethanone(5),4-hydroxy-3-methoxy cinnamic aldehyde(6),tachioside(7)on the basis of spectroscopic analysis and comparison of their spectroscopic data with literature values.[Conclusion]Compounds 1 and 3-7 were isolated from this plant for the first time.Compounds 1 and 2 could remarkable inhibit the growth of Echinochloa crusgalli at a concentration of 50μg/mL.
