【摘要】 本文以斜萼草全草为研究对象,采用各种色谱分离手段对其化学成分进行纯化,得到12个单体化合物,这些化合物经过理化数据、波谱分析和化学方法等手段鉴定为斜萼草素D (1)、斜萼草素E (2)、13-表斜萼草素E (3)、β-谷甾醇(4)、豆甾醇(5)、阿克替苷(6)、campneoside I (7)、ilicifolioside A (8)、6-表-8-O-乙酰哈巴苷(9)、筋骨草苷(10)、radulignan (11)和flacoside A (12),其中化合物1-3为新化合物,化合物6-12为首次从该种分离得到。化合物1的绝对构型由单晶衍射确定,化合物2和3的绝对构型通过化学反应生成已知化合物后反向推断确定。细胞毒活性评价结果显示,化合物3对A549和MCF-7表现出微弱的细胞毒活性,IC50分别为22.4和47.3μmol/L。
【Abstract】 Three new labdanediterpenes(1-3) andnine known compounds(4-12) were isolated from Loxocalyx urticifolius Hemsl.Their structures were determined by extensive spectroscopic analysis and chemical methods.The absolute configuration of 1 was confirmed by X-ray crystallographic analysis.Twelve compounds were identified as loxocalyxin D(1),loxocalyxin E(2),13-epiloxocalyxin E(3),β-sitosterol(4),stigmasterol(5),acteoside(6),campneoside I(7),ilicifolioside A(8),6-epi-8-O-acetylharpagide(9),ajugoside(10),radulignan(11),and flacoside A(12).The cytotoxic activities of compounds 1-3 were evaluated against the four human cancer cell lines A549,HepG2,HL-60 and MCF-7.Compound 3 showed selective cytotoxicity against A549 and MCF-7 with the IC50 of 22.4 and 47.3μmol/L,respectively.
