概要
- 論文の詳細を見る
From the leaves of Grevillea robusta, compounds whose NMR data were superimposable on those of robustasides B and C were isolated along with two new compounds, (E)-2,5-dihydroxycinnamic acid esters of arbutin and D-glucose, and two known compounds, robustaside A and (E)-2,5-dihydroxycinnamic acid. The structures of robustasides B and C were not arbutin caffeates, being revised to arbutin (E)-2,5-dihydroxycinnamic acid esters.
