From leaves of Quercus cerris L. three acylated flavonoid glycosides have been isolated and identified as 3‐ O ‐isorhamnetin 6‐ O ‐galloyl‐β‐ D ‐glucopyranoside ( 1 ), 3‐ O ‐kaempferol 4‐ O ‐acetyl‐6‐ O ‐( p ‐coumaroyl)‐β‐ D ‐glucopyranoside ( 3 ), and the already described 8) 3‐ O ‐isorhamnetin 6‐ O ‐( p ‐coumaroyl)‐β‐ D ‐glucopyranoside ( 2 ).
