In JP XI, the whole plant of Plantago asiatica L. is referred to as Plantaginis Herba and the seed as Plantaginis Semen, and both one used in folk medicine and Chinese Medicine. In order to establish a standard method of quality evaluation of the drugs, we conducted a quantitative analysis of aucubin in the drugs by extracting the powdered material with 50% MeOH using sonication and subjecting the extracted liquid to HPLC. In the case of P. asiatica, the aucubin content is high in the underground part and low in the terrestrial part. Of the leaves of one plant, younger leaves contain more aucubin than older leaves adjacent to the rhizome, and the leaves turning yellow contain little aucubin. Of various genus Plantago plants mostly collected in Japan, P. camtschatica contains a large amount of aucubin, P. major, a very small amount of it and P. japonica no aucubin.
