a Total Phenolic Content (TPC) was expressed in mg of gallic acid equivalents (GAE) per gram of extract. Values are expressed as means ± standard error; b Yield was calculated as % yield = (weight of extract/initial weight of dry sample) × 100; ** p < 0.01 compared with the control; *** p < 0.001 compared with the control.
