摘 要:采用硅胶柱、ODS开放柱和半制备液相等色谱方法相结合,从千年健根茎乙醇提取物中的乙酸乙酯部位分离得到12个倍半萜类化合物,根据理化性质和波谱分析,化合物结构分别鉴定为3α,7α-dihydroxy-cadin-4-ene(1),3-oxofabiaimbricatan(2),3β,4α-dihydroxy-7-epi-eudesm-11(13)-ene(3),integrifonol A(4),1β,6β-dihydroxy-7-epi-eudesm-11(13)-ene(5),4β,7β,11-enantioeudesmantriol(6),epi-guaidiol(7),oplopanone(8),(-)-1β,4β,6α-trihydroxy-eudesmane(9),2α-hydroxyhomalomenol(10),(-)-T-muurolol(11),hamalomenol A(12)。化合物1~7为首次从千年健属植物中分离得到,11~12为首次从该植物中分离得到。此外对分离的部分化合物进行了抑制脂多糖诱导的小鼠巨噬细胞RAW 264.7细胞NO释放实验,发现化合物3,5和8有良好的抑制活性,其IC50分别为6.51,3.25,7.78μmol·L^(-1)。Twelve compounds were isolated from alcohol extracts of the rhizome of Homalomena occulta by using various chromato- graphic techniques including column chromatography onsilica gel and Cls reverse-phase silica gel, and semi-preparative HPLC. Their structures were identified by physico-chemical properties and spectroscopic data analysis as 3α, 7α-dihydroxy-cadin-4-ene (1), 3-oxo- fabiaimbricatan ( 2 ), 3β, 4α-dihydroxy-7-epi-eudesm- 11 ( 13 ) -ene ( 3 ), integrifonol A ( 4 ), 1β, 6β-dihydroxy-7-epi-eudesm-11 ( 13 ) - ene (5), 4β, 7β, 11-enantioeudesmantriol (6), epi-guaidiol ( 7 ), oplopanone ( 8 ), ( - ) -1β, 4β, 6α-trihydroxy-eudesmane (9), 2a-hydroxyhomalomenol (10), ( - )-T-muurolol (11) and hamalomenol A (12). Compounds 1-7 were obtained from the genus Homa- Iomena for the first time and 11-12 were firstly reported from the species. Additionally, compounds 3, 5 and 8 displayed inhibitory effects against the lipopolysaccharide (LPS)-induced nitric oxide (NO) production in mouse macrophage RAW264. 7 cells with ICs0 values of 6. 51, 3.25, 7.78 μmol L-1 , respectively.
