Bioactive Compounds and Anti-Inflammatory Applications of Kaempferia Species

Kaempferia, a genus in the Zingiberaceae family native to Southeast Asia, has attracted considerable interest for its rich spectrum of bioactive metabolites and traditional use in alleviating inflammatory disorders. Key constituents include methoxyflavones—flavonoid derivatives bearing methoxy substituents—alongside diverse diterpenoids, phenolic acids and essential oils. These compounds have been shown to modulate inflammatory signalling pathways by inhibiting pro-inflammatory cytokines, suppressing inducible nitric oxide synthase (iNOS) and cyclo-oxygenase-2 activities, and blocking nuclear factor kappa-B (NF-κB) and mitogen-activated protein kinase cascades. In vitro and in vivo models demonstrate efficacy against arthritis, neuroinflammation and cutaneous inflammation, with evidence for preservation of neuronal function, reduction of oxidative stress and amelioration of pain. Advances in extraction, structural elucidation and formulation have paved the way for topical and oral applications, highlighting Kaempferia species as promising sources of novel anti-inflammatory agents with potential in chronic disease management and nutraceutical development.

Bioactive Compounds and Anti-Inflammatory Applications of Kaempferia Species publication trend

The graph below shows the total number of articles in bioactive compounds and anti-inflammatory applications of kaempferia species across all publications each year (not limited to Nature Index journals).

Technical terms

Methoxyflavones: Flavonoid derivatives bearing one or more methoxy groups, associated with anti-oxidant and anti-inflammatory properties.

Pimarane diterpenoids: Diterpene compounds featuring a pimarane carbon framework, often highly oxidised and biologically active.

NF-κB: A transcription factor central to the regulation of genes encoding inflammatory mediators.

Inducible nitric oxide synthase (iNOS): An enzyme that generates nitric oxide during inflammatory responses, contributing to tissue damage when over-expressed.

Macroemulsion: A coarse oil-in-water system stabilised by surfactants, used to deliver lipophilic extracts in topical formulations.
