“…In order to identify potentially bioactive compounds, GC-MS was initially applied to both CGEEA and CGEBU fractions after trimethylsilylation (Johnson-Ajinwo et al, 2015). These analyses (Figures S2 and S3; Table S1 and S2), indicate that 3,4,5-trihydroxybenzoic acid (gallic acid) as well as several fatty acids were present in both the CGEEA and CGEBU extracts, but also that additional benzoic acid derivatives, including 3-methoxy-4-hydroxybenzoic acid (vanillic acid, 0.4%), 3,4-dihydroxybenzoic acid (protocatechuic acid, 2%), and 3,4,5-trihydroxybenzoic ethyl ester (ethyl gallate, 2%), were also present in CGEEA.…”
