POMEGRANATE EXTRACT
70%
The
lovely and delicious pomegranate fruit reminds us of the lush gardens of
Andalucia, Spain. The name comes from Pomme de Granada, "apple of
Granada" it was thought to have originated there. Granada's
coat-of-arms still displays the picture of this exotic fruit. In
ancient times, pomegranate fruit was regarded as a symbol of fertility
due to the round shape, and abundant seeds. Recently however, science
has discovered important compounds, which indicate its benefits,
transcend ancient symbolism.
Pomegranate extract is primarily composed of alkaloids
and polyphenols. The active constituent that appears to be
responsible for its multiple health benefits is Ellagic acid. Ellagic
acid is a naturally occurring phenolic compound found in several
fruits and nuts. Pomegranate extract has demonstrated a variety of
beneficial functions including antioxidant and anti-viral activity.
In 1996, a Nottingham, PA University research team learned
that pomegranate extract could destroy several viruses nearly
on contact. The discovery of this anti-viral activity instigated
further experimentation and clinical trials. One study confirmed that
Ellagic acid effectively protects cells from damaging free radicals.
Additional phenolic compounds found in pomegranate known as anthocynadins (also well known
scavengers of free radicals) combine synergistically with Ellagic
acid to greatly augment pomegranate's potency as an
antioxidant.
Of
great importance is the pomegranate extracts potential use as a chemo-preventive
agent. Initial experimentation by Stoner and Mukhtar showed that
Ellagic acid decreased the number of chemically induced lung tumors
by 44-75%. Mukhtar further illustrated that topical application of
Ellagic acid provided protection against chemically induced skin
tumors.
Ellagic acid has several mechanisms of actions by
which it exhibits its chemo-preventive properties. Research by Barch
et al. Demonstrated that Ellagic acid could actually bind to DNA,
thus preventing its carcinogenic alteration. Additionally, Ellagic
acid has been shown to induce the production of phase 11
detoxification enzymes through its manipulation of gene expression.
With an increased concentration of these enzymes, various tissues
ability to detoxify harmful compounds is augmented. Finally, Ellagic
acid was found to be a potent inhibitor of tyrosine protein kinase, a
molecule whose activity has been associated with the ability of
certain viruses to transform normal cells into cancerous
cells.
