In order to identify the anthocyanidins of different colors,the anthocyanidins in petals of three varieties of Chinese rose from red,yellow and blue-purple were analyzed by using the methods of chromogenic reaction,paper chromatography and spectroscopy.The results showed that the anthocyanidins of'The Pilgrim'petals were mainly flavonoids,which might be chalcone,oleanone,dihydroflavone,flavonol or flavonol compounds.Antho-cyanidins in the petals of'Rouge Meilland'included cornflower centaur-3,5-glucoside,flavonoids compounds,chalcone and dihydroflavones.The'Kinda Blue'anthocyanidins were might paeoniflorin-3-rue glycoside,but may also contain chalcone and dihydroflavones.Through the measurement of the pH value of the petals at the full blos-som stage,it was further speculated that the reason of the'Kinda Blue'appears and bluish purple might be that paeoniflorin lost protons and formed bluish quinone type.
