Phytochemical Analysis and Pharmacological Applications of Zanthoxylum Species

Zanthoxylum species, members of the Rutaceae family, have long featured in traditional medicine across Asia, Africa and the Americas. Contemporary phytochemical investigations have revealed a rich chemical diversity, including furoquinoline, benzophenanthridine and isoquinoline alkaloids, alongside coumarins, flavonoids, lignans and essential oils. Advanced chromatographic and spectrometric techniques—such as high‐performance liquid chromatography coupled with mass spectrometry, nuclear magnetic resonance spectroscopy and metabolomic fingerprinting—have enabled comprehensive profiling of these compounds in roots, stems, leaves and bark. Pharmacological studies have corroborated traditional uses, demonstrating broad antimicrobial efficacy (notably against multidrug‐resistant bacteria), anti‐inflammatory and antioxidant activities, analgesic effects and cytotoxicity against cancer cell lines. Several alkaloids exhibit synergistic action with conventional antibiotics, while coumarins and flavonoids contribute to free‐radical scavenging. In vivo pharmacokinetic studies have elucidated absorption, metabolism and tissue distribution of principal alkaloids, informing dose optimisation. Ongoing efforts focus on quality standardisation, elucidation of mechanisms of action—particularly efflux‐pump inhibition and modulation of inflammatory pathways—and the development of novel therapeutics derived from Zanthoxylum phytometabolites.
