Grevillosides A–F: Glucosides of 5-alkylresorcinol derivatives from leaves of Grevillea robusta

From leaves of Grevillea robusta, six 5-aklylresorcinol glucocides, named grevillosides A–F, were isolated. Their structures were elucidated by spectroscopic analyses. From a MeOH extract of leaves of Grevillea robusta, seven compounds ( 1–7) were isolated. One known compound ( 7) was identified wit...

Description
Summary:From leaves of Grevillea robusta, six 5-aklylresorcinol glucocides, named grevillosides A–F, were isolated. Their structures were elucidated by spectroscopic analyses. From a MeOH extract of leaves of Grevillea robusta, seven compounds ( 1–7) were isolated. One known compound ( 7) was identified with a benzyl glucoside, icariside F 2. The structures of the six of these, named grevillosides A–F ( 1–6), were elucidated on detailed inspection of one- and two-dimensional NMR spectroscopic data as glucosides of 5-alkylresorcinols.
