Unlocking terpenoid treasures of rhizome and leaf volatiles of Curcuma caesia Roxb through 1D and 2D GC × GC TOFMS analysis.

ABSTRACT: The current research employed advanced GC × GC TOFMS analysis for comprehensive profiling of the essential oils (EOs) extracted from rhizomes and leaves of Curcuma caesia (black turmeric) for the first time. The study revealed a total of 151 constituents, including 97 and 114 previously undocumented compounds in rhizome and leaf oils, respectively. Sesquiterpenes and monoterpenes emerged as the predominant components, accounting for more than 60% of each oil. The predominant constituents of C. caesia rhizome EO include curzerenone (11.45%), eucalyptol (7.56%), curzerene (4.56%), epicurzerenone (4.23%), camphor (3.59%), ar-turmerone (2.59%) whereas camphor (6.59%), heptacosane (4.26%), curzerenone (3.85%), epicurzerenone (3.7%), curzerene (3.46%), eucalyptol (2.69%), α-farnesene (2.67%) wer
