Phytochemical Constituents And Pharmacological Potential Of Neolamarckia Cadamba: A Comprehensive Review

Abstract

Neolamarckia cadamba (Roxb.) Bosser, commonly known as Cadamba, is a fast-growing tropical tree belonging to the family Rubiaceae and has a long history of use in traditional medicine across South and Southeast Asia. Various plant parts, including bark, leaves, fruits, and roots, have traditionally been used for managing diabetes, liver disorders, inflammation, infections, wounds, and other chronic conditions. The plant contains diverse bioactive constituents, including flavonoids, phenolic compounds, steroids, fatty acids, indole alkaloids such as cadambine and iso-cadambine, and triterpenoids such as cadambagenic acid and betulinic acid.

Experimental pharmacological studies have demonstrated a broad range of biological activities of N. cadamba. These include antioxidant, antimicrobial, antifungal, anti-inflammatory, analgesic, hepatoprotective, anticancer, antidiabetic, anticonvulsant, and wound-healing effects. Its anticancer potential has particularly been associated with apoptosis induction and modulation of cell-cycle pathways. These findings indicate that N. cadamba may serve as a promising source of pharmacologically active compounds.

However, its translation into clinical applications remains limited due to insufficient human clinical trials, inadequate toxicological evaluation, variability in extraction methods and phytochemical composition, and incomplete understanding of its mechanisms of action. Therefore, systematic research is required to establish scientific evidence supporting its traditional uses. Future investigations should focus on standardized extraction procedures, phytochemical standardization, detailed toxicity studies, mechanistic investigations, and well-designed clinical trials to validate its therapeutic potential and facilitate evidence-based pharmaceutical development.
