The HA fraction consist of hydroxyphenols, hydroxybenzoic acids
, and others aromatic structures with linked peptides, amino-compounds, and fatty acids.
In current study, phenolic acids, such as hydroxycinnamic and hydroxybenzoic acids
, were the predominant phenolic compounds in BSG (Tsao & Yang, 2003).
2011) found that in phenolic acids such as benzoic acid, cinnamic acid, hydroxybenzoic acids
(p-hydroxybenzoic, protocatechuic, gallic acid, and syringic), and hydroxycinnamic acids (p-coumaric, caffeic and ferulic), the antimicrobial activity of the hydroxycinnamic acids was comparable or higher than that of hydroxybenzoic acids
with the same number of hydroxyl groups.
