摘要
目的研究三宝木(Trigonostemon chinensis Merr.)枝条的化学成分。方法采用多种柱色谱技术进行分离纯化,通过理化性质和波谱数据分析鉴定化合物的结构,采用滤纸片琼脂扩散法测定化合物抗菌活性。结果从三宝木枝条乙醇提取物的乙酸乙酯萃取物中分离得到了12个已知化合物,经波谱分析鉴定为松脂醇(1)、(+)-de-4″-O-methylmagnolin(2)、丁香脂素(3)、nitidanin(4)、臭矢菜素A(5)、6-deoxyjacareubin(6)、巴西红厚壳素(7)、豆甾-4,22-二烯-3-酮(8)、3β-羟基豆甾-5-烯-7-酮(9)、豆甾-4-烯-3-酮(10)、正十八酸(11)、β-谷甾醇(12)。结论 12个化合物均为首次从该植物中分离得到,其中,化合物2、4、5、8、9、10是首次从该属植物中分离得到。初步抗菌活性结果表明化合物7对金黄色葡萄球菌、烟草青枯菌具有抑制活性。
Twelve compounds were isolated from the EtOH extract of the twigs of Trigonostemon chinensis Merr. Their structures were identified as pinoresinol ( 1 ), ( + ) -de-4"-O-methylmagnolin ( 2 ), syringaresinol (3) , nitidanin ( 4 ), cleomiscosin A ( 5 ) , 6-deoxyjacareubin ( 6 ) , jacareubin ( 7 ) , stigmasta-4,22-dien-3-one (8) ,7-ketositosterol ( 9 ), sitosterone ( 10 ), stearine ( 11 ), and fl-sitosterol ( 12 ). All the compounds were isolated from this plant for the first time. Compounds 2,4,5,8,9,10 were isolated from the genus Trigonos- temon for the first time. Compounds 1 - 12 were tested by the paper disk diffusion method and compound 7 showed inhibitory effects on Staphylococcus aureus and Ralstonia solanacearum.
