Abstract: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.
