With this method, we have found that the sample of "Rose madder" contains only traces of purpurin besides of pseudopurpurin. The method is also useful for investigating madder types that contain only small amounts of purpurin (formed probably from pseudopurpurin) as well as pseudopurpurin, but no alizarin. Examples of these madder types are the South American relbun roots such as Relbunium hypocarpium (L.) HEMSL. and R. ciliatum (L.) HEMSL. and the Japanese madder roots of Rubia akane.

Rubiae Radbc is made up of locally common Rubiaceous plants Rubia akane in Japan, R. cordifolia in China, and R. tinctorum in Europe. The former two showed antineoplastic activity, but the latter did not. Because the extract of Rubiae Radix showed antineoplastic activity against sarcoma 180A, isolation was pursued for the active principles. After repeated fractionation and purification of the extract, oligopeptides were obtained as active principles against P388 leukemia. The extract was partitioned with water and benzene, and water and ethyl acetate. From both fractions, eight components were isolated as crystals, and named as RA-I-VIII (160-167) after Rubia akane 124-128). 

Stems, leaves, and flowers of Bouvardia ternifolia (Rubiaceae) from Mexico were shown to contain cytotoxic and antitumor compounds. Fractionation revealed two cyclic hexapeptides, bouvardin (26) and deoxybouvardin (27) (Fig. 37.8) (Suffness and Cordell, 1985). The antitumor effects of these compounds were attributed to the ability of these compounds to inhibit protein synthesis because of an effect on the 80-S ribosome. Similar compounds have been found to be the antitumor principles of Rubia akane and R. cordi-folia (Suffness and Cordell, 1985).
