Two quinic acid esters, 5-O-caffeoylquinic acid (1) and 5-Ocoumaroylquinic acid (2); three myricetin glycosides, myricetin 3O -L-rhamnopyranosyl(1′′′  6′′)  -D-galactopyranoside (3), myricetin 3-O -D-glucuronide (4), and myricetin 3-O -Dgalactopyranoside (5); 1,6-digalloyl -D-glucose (6); and (+)catechin (7) were isolated and identified for the first time from the leaves of Schinus terebinthifolius Raddi. Furthermore, investigation of tannic acid content was carried out by HPLC.
