Kaempferia L. is a genus belonging to Zingiberaceae family, with many species used in indigenous medicines in Asian countries. Kaempferia champasakensis Picheans. and Koonterm. are rare species found only in Laos and Vietnam. The aim of this study was to provide the micro-morphological traits and the volatile compounds of the acetone extract isolated from K. champasakensis for the first time. Using gas chromatography/mass spectrometry (GC/MS) assay, twenty-three volatile components were identified in the studied extract, among which tyranton (22.41%), 9(E), 11(E)-conjugated linoleic acid (18.58%), palmitic acid (15.32%), phytol (9.95%), 3-hexen-2-one (6.91%), cis-vaccenic acid (6.04%) and beta-sitosterol (4.74%) were the major compounds. In addition, using the iodine green-carmine double staining method, the micro-morphological traits of the leaf, root tuber, root and rhizome of K. champasakensis were first demonstrated. These results provided the standardization and classification of K. champasakensis, which can be applied in the pharmaceutical field and other related areas.
