摘要
对喙荚云实Caesalpinia minax枝和叶的化学成分进行了研究。实验采用硅胶和凝胶柱色谱法进行分离纯化,利用波谱法进行结构鉴定,从喙荚云实枝和叶的乙醇提取物中分离得到15个化合物,分别鉴定为芹菜素(1),5,7,3',4'-tetra-hydroxy-3-methoxyflavone(2),毛地黄黄酮-5,3'-二甲酯(3),thevetiaflavon(4),芹菜素-7-O-β-D-葡萄糖醛酸苷(5),bonducellin(6),7-hydroxy-3-(4-hydroxybenzylidene)-chroman-4-one(7),3-去氧苏木查尔酮(8),5-acetonyl-7-hydroxy-2-methylchromone(9),4-(trans)-acetyl-3,6,8-trihydroxy-3-methyl-dihydronaphthalenone(10),4-(cis)-acetyl-3,6,8-trihydroxy-3-methyl-dihydronaphtha-lenone(11),香草酸(12),ω-hydroxypropioquaiacone(13),丁香脂素(14)及尿嘧啶(15),化合物1～14为酚性成分。以上所有化合物均为首次从喙荚云实中得到,其中化合物1～5,9～13,15为首次从云实属植物中得到。
Fifteen compounds were obtained from the twigs and leaves of Caesalpinia minax. Their structures were identified as apigenin （ 1 ）, 5,7,3＇,4＇- tetrahydroxy-3-methoxyflavone （2）, luteolin-5, 3 ＇-dimethyl-ether （3）, thevetiaflavon （4）, apigenin-7-0-/3- D-glncuronide （5）, bonducellin （ 6 ）, 7-hydroxy-3-（ 4-hydroxybenzylidene ） -chroman4-one （ 7 ）, 3-deoxysappanchalcone （ 8 ）, 5-acetonyl-7-hydroxy-2-methyl chromone （ 9 ）, 4- （ trans ） -acetyl-3,6,8-trihydroxy-3-methyl-dihydronaphthalenone （ 10）, 4- （ c/s ） -ace- tyl-3,6,8-trihydroxy-3-methyl-dihydronaphthalenone （ 11 ）, vanillic acid （ 12 ）, to-hydroxypmpioquaiacone （ 13 ）, syringaresinol （14） and uracil （15）. All compounds were isolated from C. minax for the first time. Compounds 1-14 were phenolic compounds and compounds 1-5, 9-13 and 15 were isolated from the genus Caesalpinia for the first time.
