| Antioxidant activity | Ethanol-water extraction | The percentage of DPPH radical scavenged by CS extract was 92.6 at a concentration of 1.6 mg/ml−1 | Iran | [54] |
| Three separate solvents (ethyl acetate, ethanol, and water) | The ABTS inhibition of immature and mature silks was ranged from 13.4% to 35% and 15.56% to 44.36%, respectively | Malaysia | [16] |
| Ultrasound-assisted extraction | FRAP value of total flavonoids extracted from corn silk was 467.59 μmol/L | China | [34] |
|
| Antibacterial activity | The petroleum ether (PECS), chloroform (CECS), and methanol (MECS) extractions | PECS, MECS, and flavonoids were active against eleven bacteria out of twelve bacteria. CECS was active only against five bacteria | Malaysia | [46] |
| Ethanol, chloroform, and methanol extractions | Ethanol extract showed significant antimicrobial activity against both Gram-positive bacteria (13.17 to 9.45 mg/ml) and Gram-negative bacteria (12.36 to 8.15 mg/ml) bacteria | Bangladesh | [55] |
| Aqueous extraction | The antimicrobial activity against Staphylococcus aureus and Bacillus subtilis is 500 mg/ml and 62.5 mg/ml. The minimum inhibitory concentration to Candida albicans is 125 mg/ml | China | [27] |
|
| Antidiabetic activity | Ethanol extraction | Treatment with 300 mg/kg or 500 mg/kg of corn silk flavonoids significantly reduced the body weight loss, water consumption, and especially the blood glucose (BG) concentration of diabetic mice | China | [15] |
|
| Antifatigue activity | Hot ethanol continuous extraction | Swimming exercise results indicated that corn silk flavonoids had antifatigue activity of mice by inhibiting the production of blood lactic acid | China | [17] |
| Hot ethanol continuous extraction | Corn silk flavonoids could elevate the exercise tolerance of mice and provide protection against oxidative stress induced by exhaustive exercise in mice | China | [14] |
