| 摘要: |
| 采用常压柱色谱和重结晶相结合的分离方法,从木奶果的茎叶提取物的乙酸乙酯部分中分离得到8个化合物,通过波谱方法及与已知样品对照的手段鉴定它们为(2S,3S,4R)-2-[(2R)-2-hydroxytetracosanoylamino]-1,3,4-octadecanetriol(1),Aralia cerebroside(2),(24S)-24-ethylcholesta-3β,5α,6β-triol(3),Stigmast-4-en-6β-ol-3-one(4),7-oxo-β-sitosterol(5),7α-methoxy-sigmast-5-en-3β-ol(6),β-sitosterol(7),daucosterol(8)。化合物1-6为首次从该种植物中发现的。 |

| Abstract: |
| Eight compounds were isolated from the stems and leaves of Baccaurea ramiflora by separation method of the normal pressure column chromatography and recrystallization. On the basis of spectral data or comparison with authentic samples,they were identified as(2S,3S,4R)-2-[(2R)-2-hydroxytetracosanoylamino]-1,3,4-octadecanetriol(1),Aralia cerebroside(2),(24S)-24-ethylcholesta-3β,5α,6β-triol(3),stigmast-4-en-6β-ol-3-one(4),7-oxo-β-sitosterol(5),7α-methoxy-sigmast-5-en-3β-ol(6),β-sitosterol(7),daucosterol(8). Compounds 1-6 were firstly isolated from this plant. |
