Up to the present, phloroglucide has chemically been found in the rhizome and stipes of Dryopteris crassirhizoma Nakai and D. lacera O. Kuntze, in Japan. It was also recognized by a histochemical method in the rhizome and stipes of Dryopteris Bissetiana C. Christensen var. sacrosancta H. Ito, D. cycadina C. Christensen var. melanolepsis Nakai, D. cystolepidota C. Christensen, D. erythrosora O. Kuntze, D. pseudoerythrosora Kodama, D. Sieboldii O. Kuntze, D. tokyoensis C. Christensen, D. uniformis Makino and D. varia O. Kuntze. The method of detections was as follows: Powder of rhizome and stipes was digested for two days with carbon disulfide, the digest solution filtered and evaporated. The residue was extracted with 5% barium hydroxide, filtered, acidified with 5% hydrochloric acid, and the precipitates extracted with petroleum ether. The crystals obtained melted at 156°, corresponding to that of flavaspidic acid. A few drops of Ehrlich-Koziczkowsky's reagent added to these crystals under the microscope will allow observation of their change to reddish crystals.
