- 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.
