| Popis: | application/pdf Yellow‐flowered cyclamens contained flavonol glycosides as well as chalcononaringenin 2'‐glucoside in the petals. The yellow petals with large amount of chalcononaringenin 2'‐glucoside and small amount of flavonol glycosides were deeper than those with large amount of flavonol glycosides as well as chalcononaringenin 2'‐glucoside. Little anthocyanidin was detected in hydrolysates from the former petals. On the other hand, relatively large amount of anthocyanidin was detected in hydrolysates from the latter petals, suggesting that leucoanthocyanidins were synthesized in the latter petals. 黄色花シクラメン個体の花弁には主要花色素であるCh2'Gだけでなくフラボノール配糖体も含まれており，Ch2'Gに対してフラボノール配糖体量の少ない個体で，黄色が強く発現する傾向が認められた．また，これらの個体の花色素の加水分解物からはアントシアニジンはほとんど検出されなかった．一方，フラボノール配糖体量の多い個体の花色素の加水分解物からは比較的多量のアントシアニジンが検出され，ロイコアントシアニジンが生成されていたことが推測された． |
