金鱼藻的化学成分(英文)

Chemical Constituents from Ceratophyllum demersum (Ceratophyllaceae)

从金鱼藻(Ceratophyllum demersum L.)全草的乙醇提取物中分离鉴定了其中7个,分别为:苜蓿素-7-O-β-D-葡萄糖苷(1) , naringenin-7-O-β-D-葡萄糖苷(2) ,七叶内酯(3) ,β-谷甾醇(4) , 7α-羟基-β-谷甾醇(5) , 7α-甲氧基-β-谷甾醇(6) ,十六碳脂肪酸(7)。化合物(3)为首次从金鱼藻中分离得到。

In this paper, we represent seven compounds [tricin-7-O-β-D-ghlcoside （1）, naringenin-7-O-β-D-glucoside （2）, esculetin （3）β-sitosterol （4）, 7α-hydroxyl-β-sitosterol （5）, 7a-methoxyl-β-sitosterol （6） and palmitic acid （7） ]. All compounds were isolated from Ceratophyllum demersum L. which was collected from Lijang. We compare them with compounds isolated form the material collected from Kunming by TLC. The results show that the types of main secondary metabolite in Ceratophyllum demersum L. in Yunnan are similar.
