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tagalsin C（1）、tagalsin E（2）、tagalsin F（3）、tagalsin G（4）、tagalsin O（5）、tagalsin I（6）、tagalsin L（7）、tagalsin M（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.
