Phenylethanoid glycosides distribution in medicinal plants of Gesneriaceae

To investigate the role of distribution and phylogeny of phenylethanoid glycoside in medicinal plants of Gesneriaceae,five phenylpropanoid glycosides,acteoside,paraboside B,isonuomioside A,paraboside Ⅱ,and paraboside Ⅲ were quantitatively determined in 12 species of Gesneriaceae by HPLC. The existence and content of these compounds were analyzed. The results showed that phenylethanoid glycosides were found in the most of those plants,but the kind of phenylethanoid glycosides varied in different species. Acteoside distribute in most of this plant group,paraboside B,isonuomioside A,paraboside Ⅱ,and paraboside Ⅲ were rare in those plants. The results of this study support morphological viewpoint that Trib. Trichosporeae is more developmental than Trib. Didymocarpeae.
