“…In the extracts of the seeds and the pressed cake, several phenolic compounds were observed, including syringic acid (1), ellagic acid (2), catechin (3), quercetin (4), vanillin ( 5), eugenol (6), vanillic acid (7), and, especially, gallic acid (8) [46]. Alves et al [48] investigated the chemical composition of essential oils from various parts of C. quercifolius (leaves, flowers and bark) obtained by hydrodistillation and, using GC-MS, identified 31 compounds in the leaves (9-11, 39-66), 30 compounds in the flowers (10,12,13,42,43,44,46,49,52,54,55,58,60,(67)(68)(69)(70)(71)(72)(73)(74)(75)(76)(77)(78)(79)(80)(81)(82)(83), and 18 compounds in the stem bark (15,41,64,(84)(85)(86)(87)(88)(89)(90)(91)(92)(93)(94)(95)…”
