Comparison Study for the Phytochemical Constituents of two Curcuma Species by GC-MS Technique

Curcuma, a major Zingiberaceae genus, contains approximately 110 species throughout the Asia-Pacific region. The present work aimed to study the two Indian curcuma species, Curcuma caesia Roxb. and Curcuma angustifolia Roxb., whose rhizomes are extracted using ultrasound-assisted extraction (UAE) with chloroform solvent. The extracts are subjected to phytochemical screening and analysed employing gas chromatography-mass spectrometry (GC-MS) procedures. UAE studies of these two Curcuma species' rhizomes using chloroform as a solvent have been conducted for the first time. The chloroform extracts of Curcuma caesia and Curcuma angustifolia contain twenty-six and thirty-two components, respectively. The component with the highest area percentage in both species was 2-cyclohexen-1-one, 4-ethynyl-4-hydroxy-3,5,5-trimethyl (2CEHT), a cyclic unsaturated ketone having anticancer effects. The GC-MS measurement data and phytochemical screening results provide an update on the physiologically active phytoconstituents detected in rhizome extracts, which may be used to standardise crude plant extracts and understand the species' chemical composition and medicinal potential.
