目的 對紅樹林植物角果木根莖的石油醚部分的化學(xué)成分進(jìn)行分離鑒定。方法 運(yùn)用硅膠柱色譜、凝膠柱色譜和HPLC制備液相色譜進(jìn)行分離，確定了化合物的結(jié)構(gòu)。結(jié)果 分離得到8個化合物，分別鑒定為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為二萜類化合物，化合物6～8為四萜類化合物。結(jié)論 角果木根莖的石油醚部位的主要化學(xué)成分為萜類化合物。

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.
