The rhizome essential oil of Curcuma aeruginosa Roxb. (Zingiberaceae) from Vietnam
Abstract
The volatile compounds identified from the rhizome oil of Curcuma aeruginosa 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%).
