Abstract
Chestnut trees are one of the most important crops in the north-eastern part of Portugal,
representing millions of euros of yearly income. There are many
ancestral claims of the health benefits of the consumption of chestnut
flowers in infusions that remain unproven. In this manuscript, the
antitumor and antimicrobial potential of chestnut flowers from two
cultivars, Judia and Longal, extracted through infusions and decoctions
are reported. In terms of antitumor activity, the most sensitive cell
lines were HepG2 and HCT15 with the cultivar Judia showing higher
activity for HCT15 and Longal for HepG2, regardless of the extraction
methods. Regarding the antibacterial activity of the extracts,
decoctions proved to be more effective with lower minimum inhibition
concentrations, while infusions were better in terms of antifungal
activity. The good overall antimicrobial activity could justify the
inclusion of the flowers in food chain processing to act as a natural
antimicrobial. Furthermore, the results corroborate some of the
ancestral claims of the consumption of these flowers. © 2014 Elsevier
