본 연구는 인공 재배 산채의 생산량 및 산채의 가공제품의 개발의 증대함에 따라 야생 및 재배 참취의 품질 특성을 비교하고자 재배 및 야생 참취의 건조방법에 따른 항산화성을 비교 분석하였다. 참취의 열수 추출물의 수율은 야생참취에 비해 재배 참취에서 수율이 높았고, 블랜칭 건조추출물의 수율이 높았다. 야생 참취 추출물의 총 폴리페놀과 플라보노이드의 함량은 재배 참취 추출물보다 높았으며, 건조방법에 따른 총 폴리페놀의 함량은 블랜칭 건조추출물에서 높았고, 플라보노이드의 경우에는 생채 추출물에서 높았다. 참취의 열수 추출물의 전자공여능은 농도가 증가함에 따라 증가하였고, 블랜칭 건조의 열수 추출물에서 높은 전자공여능을 보였다. 참취 열수 추출물의 SOD 유사활성능은 추출물의 농도가 높아질수록 증가하였으며, 생채 열수 추출물에서 다른 추출물에 비해 높았다. pH 1.2에서의 아질산염 소거능은 야생 및 재배의 생채, 블랜칭건조, 생채건조 열수 추출물 순으로 높았다. Xanthine oxidase 저해활성은 열수 추출물의 농도가 증가할수록 저해효과가 높았으며, 생채건조 추출물에서 가장 높았다. Tyrosinase 저해활성과 환원력은 농도가 증가함에 따라 블랜칭 건조 열수 추출물에서 높게 나타났다. 따라서 참취의 재배 및 건조 방법에 따른 열수 추출물은 항산화성이 우수하여 천연 항산화 소재 및 기능성 식품소재로서의 활용 가능한 약용식물자원이며, 이를 활용한 가공산업 발전의 기초자료가 될 것으로 생각된다.
This study was conducted in order to analyze the polyphenol contents and antioxidant activities of hot-water extracts of Aster scaber in the wild field and cultivated field, and through the drying methods for the comparison on the quality characteristics of Aster scaber, according to cultivation and drying methods, and the development of functional materials. The extraction yield was higher in the Aster scaber cultivated field than those of the Aster scaber in the wild field, and high from the dried Aster scaber. The total polyphenol and flavonoid contents of Aster scaber hot-water extracts from the wild field were higher than those in the cultivated field. The total polyphenol contents were high in the extract of blanched and dried Aster scaber, and the flavonoid content was high in the non-treated Aster scaber. The electron donating ability (EDA) values of Aster scaber hot-water extracts were increased along with the increase of extract concentration, while the EDA of the blanched and dried Aster scaber extracts was higher than the other extracts. Furthermore, the SOD-like activity was increased by the extract concentration, and was high in the extract of the non-treated Aster scaber. The nitrite scavenging ability in pH 1.2 was high in the non-treated, blanched, dried, and natural dried Aster scaber. The xanthine oxidase inhibitory activities were increased through the increase of extract concentrations, and higher in the hot-water extract from Aster scaber in the wild field (WRA) than those in the other extracts. The inhibition of tyrosinase and reduction of power were increased by the increased extract concentration, and high in the extracts of blanched and dried Aster scaber. The reduced power was higher in the Aster scaber hot-water extracts of cultivated field, and was higher in the extracts of blanched and dried Aster scaber than those in the extracts dried through the use of other drying methods. Aster scaber has a high content of polyphenol and flavonoid, and antioxidant activities, which were developed as functional materials.
