金钟藤中酚类化合物的研究

Phenolic Compounds from Merremia boisiana(Convolvulaceae)

从金钟藤(Merremia boisiana(Gagnep.)V.Ooststr.)的地上部分分离得到8个酚类化合物。通过光谱分析,分别鉴定为东莨菪内酯(1)、七叶内酯(2)、N-p-香豆酰酪胺(3)、3,5-二咖啡酰基奎尼酸甲酯(4)、3,4-二咖啡酰基奎尼酸甲酯(5)、3,4,5-三咖啡酰基奎尼酸甲酯(6)、槲皮素(7)以及山奈酚-3-β-D-半乳糖甙(8)。这些化合物均是首次从鱼黄草属(Merremia)植物中发现。

Eight phenolic compounds were isolated from the aerial parts of Merremia boisiana （Convolvulaceae）. On the basis of the spectral data, they were identified as scopoletin （1）, esculetin （2）, paprazine （3）, 3,5-di-O- caffeoylquinic acid methyl ester （4）, 3,4-di-O-caffeoylquinic acid methyl ester （5）, 3,4,5-tri-O-caffeoylquinic acid methyl ester （6）, quercetin （7）, and kaempferol 3-β-D-galactopyranoside （8）. They were all obtained from Merremia plants for the first time.
