A Comprehensive Review on Phytochemistry and Pharmacological Potential of Annona reticulata

Annona reticulata Linn., a member of the family Annonaceae, is a widely valued medicinal plant traditionally used across India and other tropical regions. Various parts of the plant, including the leaves, bark, roots, fruits, and seeds, possess diverse phytochemicals such as alkaloids, flavonoids, phenolics, tannins, acetogenins, terpenoids, and glycosides, which contribute to its broad pharmacological profile. The present review compiles comprehensive information on the phytochemistry, ethnomedicinal relevance, and experimentally validated pharmacological activities of A. reticulata. Studies report significant antipyretic, antiulcer, antinociceptive, anthelmintic, analgesic, anti-inflammatory, antihyperglycemic, antioxidant, antimicrobial, antiproliferative, and anticancer properties. These activities are supported by bioactive constituents such as acetogenins (neoannonin, bullatacin), aporphine alkaloids (liriodenine, reticuline), and sesquiterpenes. Quantitative phytochemical analyses further highlight its high phenolic, flavonoid, and antioxidant content, particularly in roots. Preclinical investigations demonstrate dose-dependent therapeutic effects, validating many of its traditional uses. However, most findings are limited to in vitro and animal studies. Therefore, future work should focus on isolating lead compounds, elucidating mechanisms of action, establishing safety profiles, and conducting clinical evaluations. Overall, Annona reticulata represents a promising natural source of pharmacologically active molecules with significant potential for developing novel therapeutic agents.
