Phytochemical Analysis and Bioactivity of Cyperus Species

Cyperus species have long been valued for their rich array of secondary metabolites, including terpenoids, phenolics and fatty acid derivatives. Modern phytochemical investigations employ chromatographic and spectroscopic techniques to characterise these compounds, revealing complex profiles in rhizomes, leaves and essential oils. Such analyses underpin the elucidation of their diverse bioactivities, spanning antioxidant, anti-inflammatory, antimicrobial and enzyme-inhibitory properties. Compounds such as α-cyperone, mustakone, various sterols and sesquiterpenes emerge as principal bioactive agents, contributing to radical scavenging, modulation of inflammatory mediators and inhibition of pathogenic microbes. Advances in in vitro and in silico methodologies have further clarified structure-activity relationships, guiding potential applications in pharmaceuticals, cosmeceuticals and agrochemicals. Despite significant progress, clinical evaluation and safety assessments remain limited, underscoring the need for integrated studies to translate phytochemical findings into therapeutic and industrial uses.

Research from Nature Portfolio

Recent studies have delineated the chemical composition and multifunctional bioactivities of C. rotundus rhizome essential oil. Predominant constituents, including α-cyperone, cyperene and α-selinene, account for potent antioxidant capacity and protective effects against DNA damage in cellular assays. The oil further exhibits dose-dependent cytotoxicity towards neuroblastoma cells and antibacterial activity against foodborne pathogens, with greater efficacy against Gram-positive organisms. These findings spotlight the oil’s potential for food and pharmaceutical applications, linking detailed phytochemical profiles with broad-spectrum biofunctionalities.
