ABSTRACT
Eupatilin, one of representative medical components of mugwort, can be efficiently extracted from the ‘Gangwha Sajabalssuk’. The Eupatilin content may depend on environmental factors such as soil and regional climate in addition to a genetic factor and Gangwha region has a profitable environmental condition for the mugwort growth. In this study, the climatological characteristics of Gangwha was analyzed in order to find the environmental condition of mugwort containing high Eupatilin in term of atmospheric, oceanographic and land variables. The climate of Gangwha is characterized by the relatively low daily temperature and large diurnal variation with plenty of solar radiation, long sunshine duration and less cloudiness. According to our correlation analysis, the long sunshine duration and the large diurnal temperature variation are highly correlated with the Eupatilin contents. The result implies that Gangwha has the favorable conditions for the cultivation and the habitat of the high-Eupatilin concentrated mugwort. Because of the sea surrounding Gangwha Island with low salinity and moderate wind, the salt contained in sea breeze is relatively low compared to other regions. Furthermore, Gangwha has clean atmospheric environment compared to other regions because the concentrations of toxic gases harmful to crop growth such as nitrogen dioxide (NO2), sulfite gas (SO2) and fine dust (PM-10) are lower in the air. The ozone (O3) concentration is moderate and within the level of natural production. It is also found that moderately coarse texture or fine loamy soils known as good for water drainage and for the growth and cultivation of the ‘Gangwha-mugwort’ are distributed throughout the areas around mountainous districts in Gangwha, coinciding with those of mugwort habitat.

본 연구에서는 Eupatilin이 고함유된 약쑥의 생육환경을 구명하고자 하였다. 이를 위해서 먼저 선행연구를 통해 Eupatilin이 고함유된다고 알려진 강화지역의 기상학적 특성을 살펴보고, 재배지역별, 수확시기별 Eupatilin 함유량과 기상요소와의 관계를 분석 하였다. 또한 강화지역의 해양, 대기질, 토양 그리고 약쑥 생육지 분포 자료를 이용하여 환경학적 조건도 분석 하였다. 결과적으로 일조시간이 길고 일교차가 큰 지역이 유효 성분이 많이 함유된 약쑥 생산에 유리한 환경이며, 강화도는 주변 지역에 비해서 일조시간이 길며 일교차가 크기 때문에 Eupatilin 함량이 많은 약쑥의 재배 및 서식처로써 적합한 지역으로 사료되었다. 또한 강화는 약한 해풍과 주변 해역의 낮은 염분도에 의해 유입되는 염분의 양이 다른 해안지방에 비하여 낮으며 다른 지역과 비교해볼 때 청정한 대기환경을 가지고 있는 것으로 분석되었다. 이와 더불어, 강화지역은 산지 주변으로 배수가 양호한 사양질 내지 식양질이 많이 분포하는데 이러한 토양 분포는 약쑥 생육지 분포와 일치하였다. 즉, 적절한 염분의 유입과 청정한 대기 그리고 배수가 양호한 토양이 Eupatilin 함유에 유리한 환경이 되었을 것으로 사료되었다.
