Description 602-610
Hedychium species are perennial rhizomatous herbs with high-quality terpenoids. In the present study, the essential oil
yield and composition from dried rhizomes of Hedychium taxa collected from the Western Ghats of India were evaluated.
Essential oils were obtained by hydro-distillation, and the yield varied from 0.4–3.96% (v/w). The components were
identified by gas chromatography, flame ionisation detector, and gas chromatography-mass spectrometry. A total of 73
components were identified among the eight taxa, and a maximum of 90.20% (31 compounds) and a minimum of 66.41%
(36 compounds) of the oil constituents were identified from Hedychium matthewii and Hedychium forrestii var. forrestii,
respectively. β-linalool was the major constituent in the oils of Hedychium coronarium (17.72%), H. forrestii (25.38),
H. flavescens (18.64%), and H. matthewii (48.41%). β-pinene was the major constituent in the oils of H. forrestii var.
palaniense (18.31%) and H. flavum (20.17%), whereas 1,8-cineole was the dominant component in H. venustum (25.81%)
and α-cadinol in H. spicatum (18.59). The results showed that geographic factors greatly influence the essential oil
composition in Hedychium. Essential oil composition in H. coronarium and H. spicatum from the Western Ghats
significantly differs from other geographical regions of origin. Hence, H. coronarium and H. spicatum from the Western
Ghats are two chemotypes for rhizome essential oils.
