a Total phenol content (TPC) was expressed in mg of gallic acid equivalents (GAE) per gram of extract. b Total flavonoid content (TFC) was expressed in mg of quercetin equivalents (QCE) per gram of extract. c Yield was calculated as % yield = (weight of extract/initial weight of dry sample) × 100. Values are expressed as means ± standard error. * p < 0.05; ** p < 0.01; *** p < 0.001 compared with the control. AA means Anemarrhena asphodeloides. Salt-fried AA means salt-fried Anemarrhena asphodeloides.
