플라보노이드 특성에 의한 한국산 조팝나무속 식물의 분류학적 연구

Abstract

This study was conducted to investigate the flavonoid characteristics of species of genus Spiraea in Korea, to examine the systematic problems of genus Spiraea and to find out the relations among taxa. The samples used in this study were collected from fields throughout the country during the period from April 1988 to September 1991, and the plants specimens at the 7 herbariums of several universities were also included for this study. Flavonoids were separated by 2-dimensional paper chromatography. The obtained data were analysed using SPSS computer program. Based on the results, genus Spiraea was classified as 15 taxa including 12 species and 3 varieties. The flavonoids extracted from these taxa were separated into 53 kinds that could be characterized by taxa and locality. Cluster analysis showed that significant differences among taxa were found for flavonoid characteristics but not found for morphological characteristics. Based on flavonoid characteristics, Spiraea trichocarpa Nakai and Spiraea chamaedryfolia Linnaeus var. ulmifolia Maximowicz appeared to be independent line from the other taxa. Spiraea chartacea Nakai and Spiraea chinensis Maximowicz appeared to be closely related each other indicating that the former was a isolated species from the latter.
