Abstract

본 연구는 제주지역에서 생산되는 세 종류의 물과 서울지역에서 사용되고 있는 수돗물 등 네 종류의 물을 전탕용수로 하여 중요 한약재인 대황으로부터 활성성분을 추출하고 용수 중의 미네랄이 대황활성성분 추출에 미치는 효과에 대하여 비교 분석하였다. 유도결합플라즈마방출분광기와 유도결합플라즈마질량분석기를 이용하여 30여종의 미네랄과 다수의 음이온을 분석하였다. 각 전탕용수로 대황을 추출하고 그 추출액의 일부를 증발시켜 총 추출량을 구하고, 또한 HPLC를 이용하여 추출액으로부터 대황의 생리활성 성분을 분석하였다. 용수 간 총 추출량과 대황 성분함량의 차이 검정을 위하여 Kruskal-Wallis 검정을 시행하였고, 미네랄, 음이온, 총 추출량 및 성분함량과의 관계분석을 위하여 다중요인분석을 시행하였다. 분석결과 용수 중의 미네랄 함량은 대황의 총 추출량 및 성분 추출량과 높은 상관관계가 있는 것으로 나타났다. The quality of decoction water would be important for the preparation of herbal medicines. Four types of decoction water, S1, S2, S3 and S4, three types of mineral water from Jeju island and one type of tap water from Seoul region were evaluated. The contents of minerals in decoction water were analysed by ICP-AES and ICP-MS. There was significant difference in the mineral contents between the types of decoction water. The bioactive components from rhubarb were extracted with four types of water and the relationship between mineral contents in water and the extracted amounts of components was evaluated. The total extraction was calculated by evaporating water and weighing the residue. The bioactive components in rhubarb were determined by HPLC method. Kruskall-Wallis rank sum tests were used. Multiple factor analysis was used to analyze the relation between the contents of mineral and total extraction or bioactive components in the decocted solutions. Not only the total extraction but also the amount of extracted bioactive components showed statistically significant relationship with the contents of minerals and anions in decoction water.
