Research on flavonoid glycosides of tea flower in different tea plant cultivars
Twelve different flavonoid glycosides were identified and quantified by ultra-high performance liquid chromatography-mass spectrometry (UHPLC-MS) method from tea flower of five different tea plant cultivars (Meizhan, Shuigu, Huangyezao, Zhenghe Dabai, and Fujian Shuixian), which were myricetin-3-O-r...

| description | Twelve different flavonoid glycosides were identified and quantified by ultra-high performance liquid chromatography-mass spectrometry (UHPLC-MS) method from tea flower of five different tea plant cultivars (Meizhan, Shuigu, Huangyezao, Zhenghe Dabai, and Fujian Shuixian), which were myricetin-3-O-rutinoside (Myr-rut), myricetin-3-O-galactoside (Myr-gala), myricetin-3-O-glucoside (Myr-glu), quercetin-3-O-rutinoside-galactoside (Que-rut-gala), quercetin-3-O-rutinoside-glucoside (Que-rut-glu), kaempferol-3-O-rutinoside-galactoside (Kae-rut-gala), quercetin-3-O-galactoside (Que-gala), quercetin-3-O-glucoside (Que-glu), kaempferol-3-O-rutinoside-glucoside (Kae-rut-glu), kaempferol-3-O-galactoside (Kae-gala), kaempferol-3-O-rutinoside (Kae-rut), kaempferol-3-O-glucoside (Kae-glu). The contents of Kae-rut-glu and Kae-rut-gala were significantly higher than other flavonoid glycosides in tea flower, which were up to 1.208 mg/g in Meizhan and 0.962 mg/g in Huangyezao, respectively. The content of Que-rut-gala in tea flower of Zhenghe Dabai, Huangyezao, and Shuigu were significantly higher than that in others; the content of Que-rut-glu in tea flower of Fujian Shuixian was the highest among the five tea plant cultivars, which was significantly higher than that of Zhenghe Dabai, Meizhan, and Huangyezao; the amount of Myr-glu in Fujian Shuixian tea flower was four times higher than that of in others; however, its Myr-gala’s amount was the lowest in the five cultivars. The total amount of flavonoid glycosides in Zhenghe Dabai tea flower was the lowest in the five cultivars. In three kinds of flavonoid glycosides, kaempferol glycosides’ content was the highest, and myricetin glycosides’ content was the lowest, and the majority of them were glycosylated with tri-glycosides in all the tested cultivars. |
