The contents of lignans glycosides in five species of Gaultheria Kalm ex L. were measured by HPLC. The resultes proved that 5 plants collected from same place all contain lignans glycosides (LD). The contents of LD in the roots of different plants shows: G. fragrantissima>G. leucocarpa var. yunnanensis>G. leucocarpa var. cumingiana>G. tetramera>G. griffithiana, and these of the above-ground parts indicate G. fragrantissima>G. leucocarpa var. yunnanensis. The contents of LD in the leaves of G. fragrantissima and G. leucocarpa var. cumingiana are higher than those in the stems, and that in stem of G. griffithiana higher than that in its leaf and root.
