Berries are fruits characterized by being coloured and flavoured
with high anthocyanins contents which provide benefical
properties to human health. Chile produces several berries and
one of this is calafate (Berberis microphylla). There are few reports
about this native species that grows as a wild crop from Aysen
and Magallanes (in the Patagonia), although it is possible to find
it under a wide range of ecological conditions. Its fruits are an
intense purple berry with high polyphenol contents. It has been
determined that calafate possesses 18 anthocyanins derived
from glycosylated delphinidin, petunidin, malvidin, peonidin and
cyanidine. Many of them are associated with health beneficial
effects. The uptake of sources of polyphenols ensures the
scavenge of free radicals and also increases cognitive properties
and prevents or reduce the risk of neurodegenerative diseases.
In recent years, it has been proven that fruits rich in antioxidants
such as calafate, could prevent and counteract neurodegenerative
deterioration, considering functional against these diseases. The
inhibition of acetylcholinesterase enzymes (AChE) is an indicator
of neurotransmitter function in diseases such as Parkinson’s and
Alzheimer’s disease. The polyphenolic profile of calafate analyzed
throughHPLC-DAD and the antioxidant capacity by different assays
was studied. Delphinidin-3-O-hexoside, petunidin-3-O-hexoside
and malvidin-3-O-hexoside were found in calafate as major
compounds. The antioxidant capacity tests revealed high values
for this berry. Themain compounds and characteristic composition
of calafate provide biological activity and potential antioxidant
capacity. In vitro tests, Ellman esterase assay have been carried
out to confirm the reaction capacity of calafate extracts in the
action of cholinesterase. Knowing that calafate has a high profile
of polyphenols, this work is aimed to present the characteristics,
description of metabolites and the potential of calafate for nutrition
and health purposes, especially to neurodegenerative diseases.
Biography
Maria Eugenia Romero Roman is a PhD student of Agronomic Science from
the University of Concepción, Chile. She completed her Master’s Degree in Mo-
lecular Biotechnology from the University of Guayaquil, Ecuador. She worked
as Deputy Head of Department of Biotechonology in Litoral Sur Experimen-
tal Station at National Institute of Agricultural Research of Ecuador and as
Research Assistant at the University of Babahoyo, Ecuador. Currently, she is
working with calafate, analyzing it a source of functional ingredients by deter-
mining bioactive compounds, testing isolated or mixed metabolites to assay
some formulations in vitro and in vivo, in order to propose those metabolites
extracted from calafate as food supplement.
