title: [On the constituents of the root of fukuchiyama-jio, the hybrid of Rehmannia glutinosa var. purpurea and R. glutinosa forma hueichingensis].
abstract: In order to characterize the pharmaceutical utility of the root of Fukuchiyama-jio, which was produced as the hybrid of Rehmannia glutinosa LIBOSCH. var. purpurea MAKINO (Akaya-jio in Japanese) and Rehmannia glutinosa LIBOSCH. forma hueichingensis HSIAO (Kaikei-jio in Japanese) (Scrophulariaceae), we have investigated the chemical constituents of the root of Fukuchiyama-jio in detail in comparison with those of Akaya-jio and Kaikei-jio. Chemical analysis as well as quantitative one by means of gas liquid chromatography (GLC) have shown that the root of Fukuchiyama-jio contains a larger amount of iridoid glucosides as compared with Akaya-jio and Kaikei-jio. During these chemical analyses, a new ionone glucoside named oxyrehmaionoside B (7) along with melasmoside (6) were isolated as the characteristic constituents of Fukuchiyama-jio and the structure of 7 has been determined.
