요약: 국화과에 속하는 단풍취(Ainsliaea acerifolia)는 고유의 독특한 맛이 특징이며, 주요 화합물들은 항비만, 항당뇨 등의 우수한 약리작용과 건강기능성이 탁월하여 수요가 증가하고 있다. 하지만, 임간재배 기술의 부족으로 생산량과 품질이 불안정한 문제가 있어 자연채취에 의존하고 있는 실정이다. 따라서, 본 연구는 단풍취의 임간재배 환경에 따른 휘발성 성분 및 유효 성분 함량을 비교하기 위해 수행되었다. 3년생 이상의 단풍취를 채취하여 토양, 차광, 해발고도, 사면, Allelopathy 영향에 따른 휘발성 성분 (Hexanal, 2-Hexenal, (E)-, Caryophyllene)와 유효성분인 3,5-Dicaffeoylquinic acid 함량을 비교하였다. 휘발성 성분 결과, 전체적으로 침엽수림 토양, 75% 차광, 1000 m, 남사면, 신갈나무 피복 토양, 신갈나무 1:4 혼합 토양, 소나무 열수 5% 낙엽추출물에서 유의미하게 높았다. 3,5-Dicaffeoylquinic acid 함량은 혼효림 토양, 35% 차광, 1100m, 북사면, 신갈나무 피복 토양, 소나무 1:2 혼합 토양, 소나무 냉수 1% 낙엽 추출물에서 유의미하게 높았다. 본 연구 결과는 단풍취 재배 적지 조건 선정에 기초자료로 활용될 수 있을 것으로 판단된다.

Abstract: Ainsliaea acerifolia, a species in the Asteraceae family, is gaining increasing demand due to its unique taste and excellent pharmacological effects, such as anti-obesity and anti-diabetic properties, along with outstanding health benefits. However, due to the lack of cultivation techniques, its production and quality remain unstable, leading to reliance on natural harvesting. This study was conducted to establish forest-based cultivation techniques for large-scale production of A. acerifolia. The study compared the volatile and effective compound content in response to different forest-based cultivation environments. A. acerifolia older than 3 years were collected, and the effects of soil, shading, elevation, aspect, and allelopathy effect were examined by analyzing volatile compounds (Hexanal, 2-Hexenal, (E)-, Caryophyllene) and the effective compound (3,5-Dicaffeoylquinic acid). Volatile compounds showed significantly higher content in coniferous forest soil, 75% shading, 1000m elevation, south-facing slopes, oak-covered soil, oak 1:4 mixed soil, and pine leaf litter extract with 5% hot water. The content of 3,5-Dicaffeoylquinic acid was significantly higher in mixed forest soil, 35% shading, 1100m elevation, north-facing slopes, oak-covered soil, pine 1:2 mixed soil, and pine leaf litter extract with 1% cold water. The results of this study are expected to provide important foundational data for selecting suitable cultivation conditions for A. acerifolia.
