Volatile constituents of essential oils isolated from leaf and rhizome of Zingiber cassumunar Roxb.

Abstract

The composition of the essential oils of Zingiber cassumunar Roxb. from Bangladesh was examined by gas chromatography mass spectroscopy (GC-MS). Sixty-four components were identified in leaf oil and 32 components were identified in the rhizome oil, accounting for 94.60% and 98.56% of the total yields, respectively. The main components in leaf oil were sabinene (14.99%), β-pinene (14.32%), caryophyllene oxide (13.85%) and caryophyllene (9.47%). On the other hand, rhizome oil contained triquinacene 1,4-bis (methoxy) (26.47%), (Z)-ocimene (21.97%) and terpinen-4-ol (18.45%). The compositions of both oils varied qualitatively and quantitatively.
