Rapid profiling of phenolic compounds of green and fermented Bergenia crassifolia L. leaves

What is it about?

Polyphenols are responsible for the number of pharmacological effects of Bergenia. UPLC-DAD-QqQ-MS and LC-DAD-ESI-QTOF-MS were used for the rapid profiling of phenolic compounds, mainly hydrolysable tannins. Green leaves consisted of 55% ellagitannins, 29% gallic acid derivatives and 11% flavonoids, with the remaining gallic acid, arbutin, bergenin and caffeoyl quinic acid. In fermented leaves, 31% of gallic acid was found, followed with 28% ellagitannins, 18% gallic acid derivatives and 18% flavonoids, with the remaining caffeoyl quinic acid, bergenin and arbutin. Tellimagrandin I, pedunculagin, caffeoyl quinic acid, monogalloyl quinic acid, 1-O-galloylglucose and 1,2,6-tri-O-galloylglucose were identified for the very first time.

Why is it important?

It is important to highlight that this is the first study to report the compounds tellimagrandin I, pedunculagin, caffeoyl quinic acid, monogalloyl quinic acid, 1- O-galloylglucose and 1,2,6-tri-O-galloylglucose in B. crassifolia leaves.
