title: [Quality evaluation of oriental medicines. I. Quantitative analysis of marker substances in the ethical extract preparation of Hangekouboku-to].
abstract: For the purpose of evaluating a Kampo preparation, Hangekouboku-to, the contents of 6-gingerol (Gi), guanosine (Gu) and rosmarinic acid (R) in twelve kinds of ethical extract preparations were compared with the self-made decoctions. Little difference was found in the availability of the three compounds among three decoction methods. A great difference was found in the R content in the ethical extract preparations while no significant difference was found in the Gi and Gu contents, showing that they were not lost in the manufacturing process. These results suggested that Perilla Herb of quite different quality was used as raw materials.
