绿藻孔石莼脂类化学成分研究

Studies on chemical constituents of green algae Ulva pertusa

目的:研究石莼属植物孔石莼的脂类化学成分。方法:应用色谱技术进行分离和纯化,并根据理化性质和波谱数据进行结构鉴定。结果:从孔石莼的石油醚提取物中分离得到7个脂类化合物,分别鉴定为顺式细辛醚(cis-asarone,1)、反式-细辛醚(trans-asarone,2)、欧细辛醚(γ-asarone,3)、植物醇(trans-phytol,4)、植物醇硬脂酸酯(phytyl-stearate,5)、植物醇乙酸酯(phytyl-acetate,6)、异植物醇(isophytol,7)。结论:除化合物4外,其余6个化合物均为首次从该属植物中得到。

Objective： To study the compounds from Ulva pertusa. Method： The alga was extracted with ethanol, isolated and purified by column chromatography on silica gel and sephadex LH - 20. All the compounds were identified on the basis of spectral analysis （including IR, MS, NMR）. Result： Seven compounds were elucidated as cis-asarone （1）, trans-asarone （2）, γ-asarone （3）, trans-phytol （4）, phytyl-stearate （5）, phytyl-acetate （6）, isophytol （7）. Conducion： All other compounds were isolated for the first time from U. pertusa, except for the compound 4.
