Abstract
Background: There has been increasing interest in the research of flavonoids from plant
sources because of their versatile effects reported in various biological studies. The bioavailability,
metabolism, and biological activity of flavonoids depend on the configuration, the total number of
hydroxyl groups, and the substitution of functional groups about their nuclear structure. Plant organs
are the main dietary source of flavonoids for humans and have been used as a remedy in traditional
medicine. Some examples include Millettia plants which have been reported to contain several flavonoids
with pharmacological activity against multifactorial diseases.
Aim of the Study: The present study summarizes up-to-date and comprehensive information on the
pharmacological activity of flavonoids from plants of the genus Millettia.
Methods: The literature information was obtained from published and unpublished materials (theses,
dissertations, and textbooks), retrieved from databases, such as Science Direct, SciFinder, PubMed
(National Library of Medicine), Scopus, Wiley, American Chemical Society, Springer, and Web of
Science.
Results: Plants from the genus Millettia contain more than 400 different flavonoids, among which
approximately 100 flavonoids were pharmacologically active in in vitro or in vivo studies. These flavonoids
exhibited antioxidant, antiprotozoal, anti-inflammatory, and anticancer activities, among others.
Conclusion: Flavonoids from Millettia plants were reported to exhibit in vitro antioxidant, antiprotozoal,
anti-inflammatory, anticancer activities, etc. These compounds can be used as a starting point for
the development of new agents against multifactorial diseases. However, more in vivo experiments,
cytotoxicity tests, and detailed mechanism of action of Millettia bioactive flavonoids should be investigated.
Keywords:
Millettia sp., flavonoids, medicinal uses, biological activity, drug discovery, molecular targets, toxicity.
