Abstract:

Based on the SCIE database, bibliometric methodology was applied to analyze relevant records regarding
to plant polyphenols from 2002 through 2012, including years, journals, affiliations, authors, key words, discipline
distribution and research topics. Hot topics were extracted from the statistical result of key word frequency and
thematic brows. The results showed that research on plant polyphenols was active in the fields of food technology,
applied chemistry, nutrition, biochemistry, molecular biology and pharmacology. The hot topics on biological activities
of plant polyphenols focuses on: 1) in vitro and in vivo antioxidant activity of plant polyphenols; 2) anti-cancer, antiaging,
anti-cardiovascular disease activities of plant polyphenols and corresponding mechanisms; 3) absorption,
transformation and bioavailability of dietary polyphenols.
