Study of the composition and quantitative
content of polyphenolic substances in pomegranate fruit pulp
Abstract
The conditions for sample preparation of
raw materials – pomegranate pulp – for analyzing the separation of polyphenolic
substances by HPLC were proposed and quantitative determination of gallic acid
and the total content of polyphenolic substances in terms of gallic acid was
carried out. The value of the antiradical activity of fruit pulp was
determined, ranging from 677.8 mg TE / 100 g to 986.5 mg TE / 100 g. A
correlation was found between the yield of polyphenolic substances from the
samples and the severity of their antiradical properties determined in the 2,2-Diphenyl-1-picrylhydrazyl test in vitro.
Key words: pomegranate fruit pulp,
polyphenolic substances, Gallic acid, high-performance liquid chromatography,
anti-radical activity.
