Summary:Phenolic compounds, physiological properties, and digestive enzyme inhibitory effect of 70% ethanol extracts from Aster scaber with different extraction methods (stirrer extraction, SE; reflux extraction, RE; autoclave extraction, AE; low temperature high pressure extraction, LTPE; ultrasonification extraction, USE) were investigated. Total polyphenols and flavonoids contents in LTPE were significantly higher than those of other extracts. The amount of substances related to cynarin (1,3-O-dicaffeoylquinic acid) was highest in USE (34.34 mg/g), followed by LTPE (33.83 mg/g), RE (32.27 mg/g), AE (25.40 mg/g), and SE (18.17 mg/g). Chlorogenic acid (5-O-caffeoylquinic acid) and astragalin (kaempferol-3-O-glucopyranoside) were highest in AE and LTPE, respectively. Xanthine oxidase, angiotensin- I converting enzyme, 3-hydroxy-3-methylglutaryl coenzyme A reductase and acetylcholin esterase inhibitory activities of LTPE and USE at a concentration of 50 mg% (w/v) were somewhat higher than those of other extracts. The ${\alpha}$-amylase, ${\alpha}$-glucosidase, trypsin and lipase activities showed the same tendency as physiological properties (concentration of 500 mg%, w/v). Additionally, there was significantly higher or slightly lower inhibitory activity compared to the control group. These results suggest that extracts from Aster scaber have potential to act as functional materials, and LTPE and USE are superior for the enhancement of biological activity. 참취의 활용 및 생리활성을 증가시킬 수 있는 적정 추출방법을 알아보고자 상온교반, 환류냉각, 가압가열, 저온고압 및 초음파 추출법을 이용하여 추출한 두벌 째 수확 참취 추출물의 생리활성을 비교하였다. 추출 수율은 환류냉각추출, 초음파추출, 가압가열추출, 상온추출, 저온고압추출 순으로 높았다. 폴리페놀, 플라보노이드 함량은 저온고압추출에서 유의적으로 높았고, 상압가열, 고온고압, 초음파추출에서는 대등한 함량을 나타내었다. 페놀화합물 정량의 경우 chlorogenic acid 함량은 가압가열추출에서 유의적으로 높았으며 cynarin 함량의 경우 환류냉각, 저온고압 및 초음파 추출에서 유의적으로 높았고, astragalin 함량의 경우 저온고압추출에서 높은 함량이 검출되었다. Xanthine oxidase(XO), angiotensin I-converting enzyme(ACE), HMG-CoA reductase 저해활성의 경우 저온고압추출 및 초음파 추출물에서 우수한 활성을 나타내었으며, 소화효소 저해활성(${\alpha}$-amylase, trypsin, lipase)에서도 유사한 경향을 나타내었다. 이러한 결과를 종합해 볼 때 저온고압 및 초음파 추출물에서 소재 활용가치가 높을 것으로 사료되며 천연 항산화제 및 기능성 증진을 위한 소재로 이용 가능할 것으로 판단된다.
