*2.4. Quantitative Determinations of Total Phenolic Content*

The total phenolic content (TPC) of the BBE extracts was determined by Folin-Ciocâlteu spectrophotometric method according to a method described previously [14]. Gallic acid was used as a reference standard, and the content of phenolics was expressed as gallic acid equivalents (GAE) per gram of dry plant material (mg GAE/g dry plant material).
