From Plantago asiatica have been isolated phenylethanoid glycosides having antibacterial and biological activities. For the standardization of the quality evaluation of Plantaginis Herba, 7 species of Plantago spp. and 9 samples of Plantaginis Herba on the market were quantitatively analyzed for their phenylethanoid glycoside contents. It was found that they might be roughly divided into two groups, i.e. one mainly containing plantamajoside and the other containing acteoside. The species having fibrous roots, i.e. P. asiatica (P. asiatica f. paniculata), P. major, P. japonica and P. hostifolia belonged to the former group, and the species having tap roots, i.e. P. camtschatica, P. depressa, P. lanceolata and P. virginica belonged to the latter group. In each species, the amounts of these compounds contained (%) were larger in the young leaves and young spikes. P. asiatica collected in Japan contained scarcely any acteoside, though it was occasionally detected in the commercially obtained samples of P. asiatica and P. hostifolia.
