Abstract: Phenolic acids are now receiving a great deal of interest as pervasive human dietary
constituents that have various therapeutic applications against chronic and age-related
diseases. One such phenolic acid that is being utilized in traditional medicine is chlorogenic
acid (CGA). It is one of the most readily available phytochemicals that can be isolated
from the leaves and fruits of plants, such as coffee beans (Coffea arabica L.), apples
(Malus spp.), artichoke (Cynara cardunculus L.), carrots (Daucus carota L.), betel
(Piper betle L.), burdock (Arctium spp.), etc. Despite its low oral bioavailability (about
33%), CGA has drawn considerable attention due to its wide range of biological activities
and numerous molecular targets. Several studies have reported that the antioxidant
and anti-inflammatory potentials of CGA mainly account for its broad-spectrum pharmacological
attributes. CGA has been implicated in exerting a beneficial role against dysbiosis
by encouraging the growth of beneficial GUT microbes. At the biochemical level, its
therapeutic action is mediated by free radical scavenging efficacy, modulation of glucose
and lipid metabolism, down-regulation of pro-inflammatory cytokines, such as tumor necrosis
factor-alpha (TNF-α), interleukin-6 (IL-6), IL-1β, and interferon-gamma (IFN-γ),
upregulation of nuclear factor erythroid 2-related factor 2 (Nrf-2), and inhibition of the
activity of nuclear factor- κβ (NF-κβ), thus helping in the management of diabetes, cardiovascular
diseases, neurodegenerative disorders, cancer, hypertension etc. This review
highlights the natural sources of CGA, its bioavailability, metabolism, pharmacotherapeutic
potential, and underlying mechanisms of action for the clinical usefulness of CGA in
the management of health disorders.
