【摘要】 目的对圆瓣姜花(Hedychium forrestii Diels.)的根茎部分进行化学成分研究。方法对圆瓣姜花根茎的95%乙醇提取物经乙酸乙酯萃取。乙酸乙酯萃取物经硅胶、十八烷基硅烷键合相(ODS)、葡聚糖醚凝胶SephadexLH-20等色谱方法进行分离纯化,并运用MS、NMR等波谱方法鉴定化合物的结构。结果从圆瓣姜花中分离鉴定了5个化合物,分别为:5-hydroxy-3,7,4′-trimethoxyflavone(I),3,5-dihydroxy-7,4′-dimethoxyflavone(II),5-hydroxy-7-(4-hydroxy-3-methoxyphenyl)-1-(4-hydroxy-phenyl)-3-heptanone(III),(5R)-5-hydroxy-1-(3,4-dihydroxyphenyl)-7-(4-hydroxy-3-methoxyphenyl)-3-heptanone(IV),stigmast-4-en-3-one(V)。结论 5个化合物均为从该植物中首次分离得到。更多还原

【Abstract】 Objective To research the chemical constitutes isolated from the rhizomes of Hedychium forrestii Diels.Methods The rhizomes of H.forrestii Diels.were extracted with 95% ethanol,which was suspended in water and then extracted with ethyl acetate.The ethyl acetate extract was extensively separated over chromatographic methods,including silica gel,octadecylsilane(ODS),and Sephadex LH-20.These compounds were elucidated by extensive spectroscopic analysis(MS,NMR,etc.).Results five compounds,[5-hydroxy-3,7,4′-trimethoxyflavone(I),3,5-dihydroxy-7,4′-dimethoxyflavone(II),5-hydroxy-7-(4-hydroxy-3methoxyphenyl)-1-(4-hydroxy-phenyl)-3-heptanone(III),(5R)-5-hydroxy-1-(3,4-dihydroxyphenyl)-7-(4-hydroxy-3 methoxyphenyl)-3-heptanone(IV),stigmast-4-en-3-one(V).] were isolated and identified.Conclusion Five compounds were all isolated from Hedychium forrestii for the first time.更多还原
