Health functionality of apigenin: A review

Abstract

  • Background

Apigenin ($4',5,7$-trihydroxyflavone) is a naturally occurring yellow crystalline flavone aglycone widely distributed across various medicinal plants, edible herbs, and plant extracts utilized historically by humans for the management of diverse ailments and inflammatory disorders prior to its identification as a distinct core bioactive compound. Chemically insoluble in water yet readily soluble in organic solvents, apigenin exhibits a remarkable spectrum of pharmacological activities, including potent anti-inflammatory, antitoxic, and antineoplastic effects. Preclinical in vitro and in vivo investigations, alongside emerging clinical trial data, indicate that apigenin engages multiple molecular targets involved in inflammatory signaling, positioning it as a promising therapeutic candidate for chronic pathologies such as rheumatoid arthritis, autoimmune conditions, neurodegenerative disorders (including Parkinson's and Alzheimer's diseases), and various forms of cancer. Favorable pharmacokinetic characteristics—specifically delayed plasma clearance and slow hepatic degradation—enhance its systemic bioavailability and therapeutic potential in pharmaceutical applications. This review provides a comprehensive analysis of the physicochemical, pharmacokinetic, and therapeutic properties of apigenin.

  • Methods

A systematic evaluation of the scientific literature encompassing preclinical in vitro and in vivo experimental studies alongside human clinical investigations was conducted. Data regarding apigenin extraction sources, molecular mechanisms of action, pharmacokinetic profiles, and disease-modifying outcomes were systematically compiled, critically appraised, and synthesized.

  • Results

Synthesized findings confirm that apigenin acts as a potent multitarget therapeutic agent capable of modulating complex inflammatory cascades, mitigating oxidative stress, and inducing apoptosis in malignant cell lines across various disease models. Its sustained systemic retention, driven by slow hepatic decomposition and delayed plasma clearance, supports its pharmacological efficacy. However, translation into clinical practice continues to benefit from innovative formulation and delivery strategies designed to optimize cellular uptake and bioavailability.

  • Conclusions

Apigenin is a versatile dietary flavonoid with extensive therapeutic applications in the prevention and management of chronic inflammatory, neurodegenerative, and oncological diseases. Ongoing pharmacological and clinical research is essential to fully realize its potential in modern therapeutics.
