Indian cardamom, primarily grown in southern India at altitudes between 900 and 1400 meters, has been analyzed for its essential oil composition using gas chromatography-mass spectrometry (GC-MS).
The study found significant levels of the major monoterpene 1, 8-Cineole, with concentrations between 28.94% and 34.91% in various cardamom varieties, along with other important monoterpenes.
Additionally, the research identified sesquiterpenes and ester constituents, highlighting α-Terpinyl acetate as the most prominent ester in one variety, marking the first detailed report on the phytochemical profiles of recent Indian cardamom varieties.
