Abstract
The genus Kaempferia (Zingiberaceae) is well-known for its diverse phytochemical constituents and characteristic essential oil. Kaempferia champasakensis was firstly described in 2008 by Chayan Picheansoonthon and Supachai Koonterm in Champasak province of Southern Laos. To date, little is known about phytochemical components and pharmacological activities of the plant. In the present study, the extraction of essential oil from K. champasakensis leaves as well as Gas Chromatography - Mass Spectrometry (GC/MS) profile were investigated. The major components in essential oil extracted from K. champasakensis leaves were determined as β-caryophyllene (16.07%), β-elemenone (14.53%), β-pinene (13.80%), germacrone (9.85%), myrcene (9.46%) and diisooctyl phthalate (8.62%). This is the first report on chemical constituents of essential oil extracted from the leaves of K. champasakensis.
