Flower petal anthocyanidins were analyzed by high-performance liquid chromatography (HPLC) in Lychnis senno, a traditional ornamental plant conserved in Japan, and its related species (Caryophyllaceae). According to the anthocyanidin composition, 8 species analyzed were classified into 4 types. For Type-I species (L. senno), flower color was vivid red (JHS 0707), and petals accumulated both 3'-hydroxylated anthocyanidins (cyanidin and peonidin) and pelargonidin. Both Type-II and Type-III species contained only 3'-hydroxylated anthocyanidins in their flower petals. For Type-II species (Silene. coeli-rosa 'Cherry Blossom' and S. yunnanensis), flower color was light purplish pink (JHS 9203) or deep purplish pink (JHS 9205), and the relative level of cyanidin in petals was much higher than peonidin. On the other hand, for Type-III species (L. coronaria), flower color was vivid reddish purple (JHS 9207), and the relative level of peonidin in petals was much higher than cyanidin. For Type-IV species (L. chalcedonica, L. coronata, L. miqueliana and L. wilfordii 'Karafuto-enbisennou'), flower color was vivid reddish orange (JHS 0706), strong orange (JHS 1305) or strong reddish orange (JHS 0713), and flower petals exclusively accumulated pelargonidin. When L. senno (Type-I) and L. miqueliana (Type-IV) were analyzed by HPLC for anthocyanin composition in flower petals, only No. 4 peak was common to these species, indicating that this peak may be a pelargonidin-type anthocyanin. The results obtained in the present study may be helpful in systematic breeding for flower color alteration of L. senno and its related species.
