摘要
从狭叶香蒲(Typha angustifolia L.)的干燥花粉中分离到5个化合物,经理化试验和波谱分析其中4个化合物的结构确定为7-甲基-4-三十烷酮(7-methyl-4-triacontanone,Ⅰ)、6-三十三烷醇(6-tritriacontanol,Ⅱ)、二十五烷(pentacosane,Ⅲ)和β-谷甾醇棕榈酸酯(β-sitosterol patmitate,Ⅳ),另外还分得一个化合物Ⅴ。Ⅳ是降低血清胆固醇的有效成分。Ⅰ、Ⅱ是新化合物。
Five aliphatic compounds were isolated from the pollen of Typha angustifolia L.(Typha- ceae).Two of them are new compounds.On the basis of spectroscopic analysis the structure of compound Ⅰ and Ⅱ was elucidated as 7-methyl-4-triacontanone and 6-tritriacontanol,res- pectively.Pentacosane (Ⅲ)and β-sitosterol palmitate (Ⅳ)also been isolated and identified. The other one (Ⅴ) have not been identified yet.The compound Ⅳ showed significant effect in lowering the serum cholesterol.
