摘要: 研究海南染木树茎的化学成分,采用硅胶、Sehadex LH-20、ODS、HPLC等色谱技术对海南染木树茎乙醇提取物的乙酸乙酯部位进行分离和纯化,结合光谱数据和理化性质鉴定化合物的结构,分别为:4-甲基苯并喹啉-5,10-二酮(1)、白兰花碱(2)、鹅掌楸碱(3)、吲哚-3-甲醛(4)、羽扇豆醇(5)、霍烷-3,30-二醇(6)、熊果酸(7)、白桦酯酸(8)、30羟基羽扇豆醇(9)、豆甾醇(10)、3β-乙酰基齐墩果醛(11)。其中,化合物4、7为首次从染木树属植物中分离得到,5、6、8、9~11为首次从该植物中分离得到。首次对化合物2的碳谱数据进行了归属。

Abstract: Eleven compounds were isolated from the ethyl acetate portion of the stem of Saprosma hainanense, including four alkaloids,six triterpenes and one sterol.On the basis of spectral data and chemical evidences,their structures were identified as cleistopholine(1),michelalbine(2),liriodenine(3),1H-indole-3-carboxaldehyde(4), lupeol(5), 21-H-Hop-22(29)-ene-3,30-diol(6),ursolic acid(7),betulinic acid(8),30-hydroxylupeol(9),stigmasterol(10),3β-acetyl oleanolic aldehyde(11).Compounds 4 and 7 were isolated from this genus for the first time,while 5,6,8 and 9-11 were isolated from the plant for the first time.Compound 2 has no 13C-NMR data reported until now.
