Abstract

In this study, the antioxidants and anti-inflammatory activities of five Aster species were compared under two drying methods: freeze-drying (FD) and air-drying (AD). Each sample was extracted using 50% ethanol for 45 minutes via ultrasonic extraction, a condition optimized through preliminary experiments. Extraction yield differed significantly depending on species and drying method. Total polyphenol and flavonoid contents were higher in Aster × chusanensis (FD: 73.0 ㎎ TAE·g-1; 55.5 ㎎ NE·g-1) and A. danyangensis (FD: 61.7 ㎎ TAE·g-1; 42.6 ㎎ NE·g-1) under FD than under AD, whereas the opposite trend was observed in A. pseudoglehnii (AD: 81.2 ㎎ TAE·g-1; 72.8 ㎎ NE·g-1) and A. hayatae (AD: 55.9 ㎎ TAE·g-1; 39.4 ㎎ NE·g-1), which showed higher levels following AD treatment. DPPH and ABTS radical-scavenging activities also displayed species-specific responses depending on the drying method. In the anti-inflammatory assay, nitric oxide (NO) production was inhibited to different extents depending on both species and drying methods. These findings indicate that even within the same genus, the preservation and enhancement of bioactivity can differ substantially depending on intrinsic species characteristics and drying processes. This study underscores the importance of drying methods in maximizing bioactive properties for the development of functional foods and bio-health ingredients.
