Abstract:

Specific chemical reactions, ultraviolet-visible spectroscopy, infrared absorption spectroscopy, and high
performance liquid chromatography-mass spectrometry (HPLC-MS) analyses indicated that polyphenols from blueberry
leaves contained the characteristics groups of hydroxide radical, glycosyl, benzene ring, methoxyl and oxygen heterocycle.
The maximum absorption wavelengths of polyphenols from blueberry leaves were 354 nm and 748 nm in alcohol. Five
individual polyphenols i.e., epigallocatechin gallate, chlorogenic acid, methyl-sinapic acid-hexoside, 5-O-feruloylquinic acid
and ouercetin 3-O-glucoside were tentatively identified by comparing their mass spectral data and retention times with those
of reference standards and published data.

Key words: polyphenols from blueberry leaves, composition analysis, high performance liquid chromatography-mass spectrometry (HPLC-MS)
