• Quercus coccifera
• megastigmane glycoside
• phenolic compounds
• spectroscopic analysis

Three new secondary metabolites kermesoside (1), cocciferoside (2) and (-)-8-chlorocatechin (3), were isolated from the the stems with barks of Quercus coccifera along with five known phenolic compounds, 3-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-propan-1one (4) and 3-hydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-propan-1-one (5), trans-resveratrol-3-O-beta-glucopyranoside (6) lyoniresinol-9-O-beta-xylopyranoside (7), lyoniresinol-9-O-beta-glucopyranoside (8). The structure elucidation of the isolated compounds was performed by spectroscopic methods (UV, 1D- and 2D- NMR and HR-MS).
