Nitrile-containing phenolic glucosides from the leaves of Glochidion acuminatum.
From the EtOAc-soluble fraction of a MeOH extract of the leaves of Glochidion acuminatum, six new compounds along with five known ones were isolated. The structures of the new compounds were elucidated to be two gallates, a p-hydroxybenzoate and an (S)-2-(4-hydroxycyclohex-1-en-1-yl)acetate of a nitrile-containing phenolic glucoside, methyl 2-(2-hydroxyphenyl)acetate β-D-glucopyranoside, and (S)-methyl 2-[4-sulfooxycyclohex-1-en-1-yl]acetate on the basis of spectroscopic evidence.
