RESUMEN
OBJECTIVE: To analyze the constituents from the rhizomes of Atractylodes lancea and A. chinensis in essential oils. METHOD: GC-MS method was used. RESULT: 32 and 29 compounds were identified respectively. CONCLUSION: The main constituents in the essential oils from the rhizome of A. chinensis are beta-eudesmol or a mixture of beta-eudesmol and atractylone, whereas from that of A. lancea are hinesol, a mixture of beta-eudesmol and atractylone, and atractylone.

The constituents of the essential oils obtained from the leaves of Artemisia argyi, A. argyi cv.qiai, A. lavandulaefolia, A. mongolica, A. princeps and A. argyi var. gracilis were analysed by GC-MS. 96 compounds including alpha-thujene, 1,8-cineole, camphor and artemisia alcohol, etc. were identified. Their percentages in the oils were given.

The chemical constituents of the essential oils obtained from the leaves of Vitex negundo var. cannabifolia, V. negundo var. heterophylla, V. negundo and V. trifolia were analysed by GC-MS. Forty compounds including alpha-pinene, linalool, terpinyl acetate, beta-caryophyllene and caryophyllene oxide, etc. were identified. Their percentages in oils were given.
