摘要
目的:对水龙骨科Polypodiaceae石韦属植物光石韦Pyrrosiaclavata(Bak.)Ching的化学成分进行研究。方法:光石韦用90%乙醇回流提取,依次用石油醚、乙酸乙酯、正丁醇萃取,对各萃取部分采用各种柱色谱进行分离纯化,通过波谱数据分析(1H—NMR,13C—NMR,MS)进行结构鉴定。结果:从中分离鉴定了8个化合物,其中包括1个何柏烷型三萜、3个脂肪酸类化合物,1个(口山)酮苷和3个其他类化合物,分别鉴定为里白烯(diploptene,1),正三十一烷(hentriacontane,2),十六烷酸二十八烷酯(octacosylpalmitate,3),二十二烷酸二十烷酯(eicosylbehenate,4),芒果苷(mangiferin,5),β-谷甾醇(β-sitosterol,6),胡萝卜苷(daucosterol,7)和蔗糖(sucrose,8)。结论:其中化合物1—4为首次从光石韦中分离得到。
Objective: To study the chemical constituents of P. clavata (Bak.) Ching. Method: The whole plant of air-dried P. clavata was extracted with 90% EtOH. The extract was suspended in H20 and extracted with petroleum ether, EtOAc and n-BuOH, successively. The compounds were isolated and purified by column chromatography, and identified based on spectral analyses ( MS,1 H-NMR,13 C-NMR). Result : Eight compounds were isolated from P. clavata, and characterized as diploptene (1), hentriacontane (2), octacosyl palmitate (3), eicosyl behenate ( 4 ), mangiferin ( 5 ), β-sitosterol ( 6 ), daucosterol ( 7 ) and sucrose (8). Conclusion: Compounds 1-4 were obtained from P. clavata for the first time.
