摘　　要：以5个苯乙醇苷类化合物为对照品,采用HPLC-UV测定其在苦苣苔科药用植物中分布情况,探讨苯乙醇苷类成分在该科药用植物中的分布规律及系统发育上的重要作用。结果显示,苯乙醇苷类成分广泛分布在苦苣苔科植物中,但不同种类的苯乙醇苷类成分在不同植物类群中分布有明显差异;阿克苷在本科植物分布广泛。paraboside B,isonuomioside A,parabosideⅡ,parabosideⅢ在自然界比较少见,在本类群呈间断分布。研究结果从化学成分方面佐证了形态学支持的苣苔科芒毛苣苔族比长蒴苣苔族进化的观点。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 m were rare in those plants. The results of this study support morphological viewpoint that Trib. Trichosporeae is more developmental than Trib. Didymocarpeae.
