The Leaves and Rhizomes Essential Oils of Alpinia oblongifolia Hayata

In the present communication, the volatile compositions of the leaves and rhizomes of Alpinia oblongifolia Hayata were reported. The essential oils were obtained by separate hydrodistillation of the air-dried leaves and rhizomes of A. oblongifolia which were collected from Xuan Lien Natural Reserve, Thanh Hoa Province, Vietnam, in May 2014. The yields of the essential oils were 0.18% (v/w) and 0.12 (v/w) respectively, calculated on a dry weight basis. The chemical compositions of the oils were characterized by using gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC-MS). The result indicated that β-pinene (17.9% and 26.2%), α-phellandrene (3.5% and 11.7%), limonene (11.1% and 14.5%) and methyl cinnamate (16.7% and 4.1%) were the significant compounds of the essential oils. This is the first report on the volatile constituents of A. oblongifolia.
