Five samples of lavenders including four different varieties were collected in Hokkaido Furano area from five different populations. The flowering tops of the samples were soaked into dichloromethane and the extracts were analyzed using GC/MS. Fifty four peaks were observed and 45 of them were identified or their reasonable structures were estimated. Most abundant components common to all samples were linalyl acetate (1), linalool (2), lavandulyl acetate (3), coumarin (4), (E)-β-farnesene (5), 7-metheoxy coumarin (6). Statistical analyses (a clustering analysis, a principal component analysis) were performed on the abundance of the 54 components. The results were as follows: (1) Chemical profiles of the samples which belong to the same variety collected at the same site were essentially the same regardless their collecting time of the day. (2) The difference in the variety resulted in different chemical profile.
