abstract: Xiangru (Labiatae) is a well-known drug used in Chinese traditional medicine. Chemical constituents of essential oils from Elsholtzia splendens and cultivated Mosla chinensis were compared by GC-MS/DS combination on SE-54 capillary column (30 m x 0.32 mm). Forty-three components were identified in Elsholtzia splendens Nakai ex F.Maekawa. The total content of the components in the essential oil was found to be 90.61%. Among them the major constituents are elsholtzia ketone (80.81%). Fifty components were identified in cultivated Mosla chinensis, with a total content of 93.91% in the essential oil.
