This study aimed to investigate the antioxidant, antimicrobial and anti-inflammatory effects of Anemarrhena asphodeloides extracts using supercritical extraction. In the antioxidant test, the total concentration of polyphenol compounds was determined to be 22.58 mg/g (supercritical extraction), 18.75 mg/g (ethanol extraction) and 17.69 mg/g (hydrothermal extraction). The DPPH radical scavenging effects were 89.84% (ethanol extraction) and 64.86% (supercritical extraction) at 2000 mg/L. ABTS radical scavenging ability had an IC50 value at 250~500 mg/L for supercritical extraction, higher than that for hydrothermal and ethanol extractions. At 1000 mg/L, elastase inhibition rates were 64.08% for ethanol extraction and 45.84% for supercritical extraction. The antimicrobial effect of the supercritical extraction was higher than that of hydrothermal and ethanol extractions. NO production with stimulated LPS was decreased in a concentration-dependent manner and, at 20 ㎛/mL, NO production was reduced by 77% for supercritical extraction compared with 46% (ethanol extract) and 63% (hydrothermal extract). Here, we confirmed that superficial extracts of Anemarrhena asphodeloides displayed excellent antioxidant, antimicrobial and antiinflammatory effects and have potential to be used as a safe and natural cosmetic material in the future.
