The rhizome essential oil of <i>Curcuma aeruginosa</i> Roxb. (Zingiberaceae) from Vietnam

Abstract

The volatile compounds identified from the rhizome oil of <em>Curcuma aeruginosa </em>Roxb (Zingiberaceae) collected from Cham Chu Natural Reserve, Tuyen Quang Province, Vietnam, are reported. The plant sample was air-dried for two weeks under laboratory shade. Essential oils were obtained by hydrodisitllation in a Clevenger-type apparatus. The yield of the oil was 0.18% (v/w) regarding the dry weight of the plant material. The constituents of the oil were analyzed by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC/MS). The main constituents of the oil were found to be β-pinene (21.9%), neocurdione (16.1%) and curcumol (15.2%).
