삼백초(三白草) 재배에 있어서 토성에 따른 생육과 유효성분을 분석하여 안정적인 재배법을 확립하고 고품질 삼백초를 생산하고자 시험을 수행한 결과를 요약하면 다음과 같다. 가. 삼백초의 절수와 엽수, 분지수는 토성 간 차이가 없었으며, 주당 줄기와 잎의 무게는 사양토가 가장 많고, 양토, 식양토, 사토의 순으로 무거웠다. 직경 5mm이하 뿌리는 토성 간차이가 없었으나, $5.1{sim}10.9;mm$의 굵기는 사양토, 양토 그리고 식양토에서 $437{sim}465;g$로 차이가 없었고, 11 mm이상은 식양토가 많았다. 건물율은 $19.1{sim}20.8%$로 차이가 없었다. 나. 잎의 quercetin-glycoside 함량은 양토와 사양토에서 $219.3{sim}222.4;mg/100;g$로 가장 높았으며, quercitrin>rutin>isoquercitrin>hyperin의 순으로 높았다. 줄기는 사토와 사양토가 각각 14.8 mg/100 g과 12.4 mg/100 g로 가장 많았으며, quercetin-glycoside 중 rutin이 가장 높았다. 다. 뿌리의 lignans 함량은 식양토, 양토, 사앙토, 사토의 순으로 높은 경향이었으며, lignans 관련 물질 중 manassatin B가 가장 많았다.
This study was carried to investigate the effect of soil texture on the growth and the contents of quercetin-glycoside and lignans, and to improve the qualities of Saururus chinensis Baill. Soil texture resulted no significant effects on the number of nodes, the number of leaves, the number of branches and dry matter ratio. However, the shoot dry weight was higher in sandy loam, loam, silt loam and sand soil in that order. Although the weight of rhizomes of below 5 mm in diameter was not significantly different among soil textures, the weight of rhizomes between 5.1 and 10.9 mm and the weight of rhizomes of above 11 mm in diameter ranged $437{sim}465;g$ and was larger in clay loam than in other soil textures. No significance difference was showed in rhizome dry ratio ranging from 19.1 to 20.8%. The amount of quercetin-glycoside in leaves was higher in loam and sandy loam and ranged from 219.3 to 222.4 mg/100 g of quercetin-glycoside quercitrin, rutin, isoquercitrin and hyperin were higher in that order. On the other hand, quercetin-glycoside contents in stem were 14.8 mg/100 g and 12.4 mg/100 g in sandy and sandy loam, respectively, and were higher than in other soil textures of quercetin-glycoside constituents, the content of rutin was the highest. The content of lignans was increased in clay loam, loam, sandy loam, and sandy in that order of lignans, the manassatin B was the highest.
