角果木根茎的石油醚部位化学成分研究

Chemical constituents in petroleum ether part in rhizome of Ceriops tagal

目的对红树林植物角果木根茎的石油醚部分的化学成分进行分离鉴定。方法运用硅胶柱色谱、凝胶柱色谱和HPLC制备液相色谱进行分离,确定了化合物的结构。结果分离得到8个化合物,分别鉴定为tagalsinC(1)、tagalsinE(2)、tagalsinF(3)、tagalsinG(4)、tagalsinO(5)、tagalsinI(6)、tagalsinL(7)、tagalsinM(8)。化合物1～5为二萜类化合物,化合物6～8为四萜类化合物。结论角果木根茎的石油醚部位的主要化学成分为萜类化合物。

Objective To separate the chemical constituents in the part of petroleum ether of mangrove plant Ceriops tagal rhizome. Methods Silica gel column, Sephadex LH-20, and HPLC as separation method were used, and the compound structures were identified. Results Eight organic compounds were isolated and named as tagalsin C （1）, tagalsin E （2）, tagalsin F （3）, tagalsin G （4）, tagalsin O （5）, tagalsin I （6）, tagalsin L （7）, and tagalsin M （8）. Compound 1--5 were diterpenoids, compound 6--8 were dimeric diterpenoids. Conclusion Terpenoids are the essential components in the part of petroleum ether of C. tagal rhizome.
