To clarify the variation in the pharmacologically active components of the essential oil contained in the rhizomes of Atractylodes lancea and A. chinensis growing in China, we transplanted the rhizomes of the wild plants from 18 populations, including A. koreana, in the same experimental field.
In order to transform main active ingredient of volatile oil, endophytic fungi were screened from the root of Atractylodes lancea. Transformation method was used in vitro. The changes of volatile oil were traced by gas chromatography. One endophytic fungus (strain ALG-13) which could uitilize
Rhizomes of Atractylodes lancea are used in traditional Japanese medicine (Kampo) and Chinese medicine to treat numerous diseases and disorders because they contain many pharmacologically active compounds. The major active compounds in A. lancea are essential oil compounds such as β-eudesmol,
Lipophilic extracts of Atractylodes lancea rhizomes exhibited potent inhibitory activities in 5-lipoxygenase [IC50 (5-LOX) = 2.9 micrograms/mL (n-hexane extract)] and cyclooxygenase-1 [IC50 (COX-1) = 30.5 micrograms/mL (n-hexane extract)] enzymatic assays. Bioactivity-guided fractionation of the
To study the fingerprint of the volatile oil of Atractylodes lancea (Thunb.) DC., and to offer the characteristic data for the quality evaluation, GC-MS analysis was performed for 17 samples of different areas used as Atractylodes lancea (Thunb.) DC. Nine kinds of same components were selected. TIC
Supercritical fluid was used to extract volatile components from the rhizoma of Atractylode lancea (A. lancea). An orthogonal array design (OAD), L(9) (3)(4), was employed as a chemometric method for the optimization of the supercritical fluid extraction (SFE) of volatile compounds from the herbal
Atractylodes rhizome is a valuable traditional Chinese medicinal herb that comprises complex several species whose essential oils are the primary pharmacologically active component. Essential oils of Atractylodes lancea and Atractylodes koreana were extracted by hydrodistillation, and the yield was
