건조 방법에 따른 산사과 추출물의 항산화 및 생리활성

Abstract

This study was performed to determine the effects of drying methods (HD, hot air drying; FD, freeze-drying) onthe antioxidant and physiological abilities of Haw (Crataegus pinnatifida Bunge). Powder color values of dried Haw, L and b, were higher for HD, while the chroma values were higher for FD. The total polyphenol, and flavonoid contents of HD Haw and FD Haw were found to be 9.29±0.50 mg GAE/mL and 15.48±0.38 mg GAE/mL, and 9.41±0.26 mg RHE/mL and 26.46±0.34 mg RHE/mL, respectively. DPPH radical scavenging abilities at 100 mg/mL concentration were higher for FD (64.90%) than HD (28.66%), as were the reducing power, ABTS radical scavenging ability, and nitrite scavenging ability. However, the HMG-COA reductase of HD (74.67%) was higher than that of FD (72.10%). The α-glucosidase inhibitory abilities of HD and FD at a concentration of 0.1 mg/mL were 24.69% and 97.38%, respectively. These results indicate that Haw is a potential functional material and that freeze-drying Haw is better than hot air drying.
