At present, there has been a great interest in producing foods
that provide beneficial effects on human health. As a result,
many native fruits have been studied for being a great source of
antioxidants and functional foods. Agriculture has the purpose of
producing high quality foods with beneficial potential for health,
such as antioxidant compounds that can avoid the free radicals
involved in oxidative stress. Chilean strawberry (Fragaria chiloensis
ssp., chiloensis f. chiloensis) is an endemic wild species, native to
southern Chile. The Fragaria chiloensis is distributed in the center
and south of Chile and has a low consumption within Chile and
a low impact on the external market. However, the antioxidant
activity and part of the phenolic composition of extracts of this
species have been analyzed by some authors resulting to be
a fruit with high capacity. This work focuses on the content of
ellagic acid and ellagitannins found in white strawberry fruits
(Fragaria chiloensis spp., chiloensis form chiloensis) of two
Chilean localities. The identification and quantification of phenolic
compounds (anthocyanins, ellagic acid and ellagitannins) of
white strawberry was made from a water/methanol/formic acid
extract and through HPLC-DAD. The results show that the major
compounds in Chilean strawberry were the derivatives of ellagic
acid and ellagitannins, besides it is observed that the two localities
do not have differences in the contents of these compounds. Also,
anthocyanins, specifically cyanidin-3-O-glucoside, pelargodinin-3-
O-glucoside and cyanidin-malonyl-glucoside were also detected.
From these preliminary results, we can assure that the Fragaria
chiloensis turns out to be a promising fruit that offers benefits to
the human health.
