Flavonoids from leaves and exocarps of the grape Kyoho
We analyzed and compared profiles of flavonols extracted from leaves and exocarps of the grape Kyoho by TLC, HPLC and UV spectrophotometry. In the exocarps, quercetin 3‐O‐glucoside was the main compound while isorhamnetin 3‐O‐glycoside (I) was present in minor amounts. In leaves, on the other hand, quercetin 3‐O‐glucoside and quercetin 3‐O‐glucoside‐7‐O‐glucronide were the major compounds while isorhamnetin 3‐O‐glycoside (II) and kaempferol 3, 7‐O‐diglycoside were present in minor amounts.
