한국산(韓國産) sedum속(屬) 식물(植物)의 화학적(化學的) 분류(分類)

The composition of the phenolic compounds of 14 species, 2 varieties and I taxon of the Sedum plant in Korea were studied to identify their inter-specific relationships and their taxonomical position. The phenograms and contour diagrams obtained from the HPLC of EtOAc soluble fraction of these plants were classified into 7 alliances according to their chemical patterns. These chemical patterns agreed with Satake's classification except for Sedum aizoon. These plants were subdivided into 5 alliances in the Sedum section and 2 alliances in the Hylotelephium section. I type of the Sedum spectabile showed a difference in the number of stamens, it could be trated as another category above variety according to this result.
