Variations in the Volatile Compositions of Curcuma Species

Abstract

Curcuma species have been cultivated in tropical and subtropical regions in Asia, Australia, and South America for culinary as well as medicinal applications. The biological activities of Curcuma have been attributed to the non-volatile curcuminoids as well as to volatile terpenoids. Curcuma essential oils have demonstrated a wide variety of pharmacological properties. The objective of this work was to examine the variation in the compositions of Curcuma rhizome essential oils. In this work, the volatile oils from C. longa and C. zedoaria were obtained and analyzed by gas chromatography-mass spectrometry. The chemical compositions of C. longa and C. zedoaria essential oils, including those reported in the literature, were analyzed by hierarchical cluster analysis. In addition, cluster analyses of the chemical compositions of C. aromatica and C. aeruginosa from the literature were also carried out. Curcuma longa volatiles were dominated by α-turmerone, curlone, ar-turmerone, β-sesquiphellandrene, α-zingiberene, germacrone, terpinolene, ar-curcumene, and α-phellandrene and showed four distinct chemical clusters. C. zedoaria rhizome oil contained 1,8-cineole, curzerenone/epi-curzerenone, α-copaene, camphor, β-caryophyllene, elemol, germacrone, curzerene, and β-elemene and showed two different chemical types. C. aromatica had three clearly defined clusters, and C. aeruginosa had three types.

Effects of dietary turmeric and clove powder on growth and immune response of the Nile tilapia

“…In the present study, notably, the dietary TP+CBP mixture incorporation followed by TP and CBP were seen to markedly increase the hepatic levels of CAT, SOD, and GSH before and after bacterial infection. The antioxidant capability of TP may be returned to its potent content of curcumin, ascorbic acid, and 1,8-cineole that can exhibit a strong free radicals action (Singh et al, 2010;Dosoky et al, 2019). Moreover, the powerful antioxidant activity of clove could be attributed to its high content of eugenol, eugenol acetate, and thymol (Gülçin et al, 2012;Nam and Kim, 2013).…”

Curcuma longa L. Rhizome Essential Oil from Extraction to Its Agri-Food Applications. A Review

“…On the other hand, several studies corroborate that the qualitative and quantitative chemical compositions of turmeric rhizomes essential oil may fluctuate according to many factors [ 124 , 148 , 149 ]. Sometimes, different chemical compositions come from the intrinsic characteristics of each genotype.…”

Polyploidy in the Ginger Family from Thailand

“…The biological activities of Curcuma have been attributed to the non-volatile ingredients of the rhizome, cucurminoids (e.g. curcumin), as well as to the volatile terpenoids [37]. Curcumin has been shown in experiments to have strong anti-inflammatory and antioxidant effects [29,36].…”
