ResumoForty-six polygonaceous plants were examined regarding the nature and amount of anthocyanidins which were obtained as the HCl-hydrolyzate of leaf proanthocyanidins. All of the plants examined contained cyanidin in common in their hydrolyzed leafextracts. From this survey, at least three groups of plants may be distinguished; the first containing only cyanidin, the second delphinidin in addition to cyanidin and the third an unknown anthocyanidin (called PA-X) and cyanidin. Of the plants examined,Polygonum cuspidatum leaves yielded cyanidin in the largest amounf. There were no geographical and seasondl variations of the distribution pattern of pigments in the plants, and also no variation of anthocyanidin-types was observed in young and mature leaves. A further survey of anthocyanins in the plants revealed that delphinidin glycosides are present in the sepals ofPolygonum nepalense andP. thunbergii.
