The region containing 18S rRNA gene, ITS 1 and part of the 5.8S rRNA gene of the Atractylodes japonica Koidz was amplified by PCR and the product cloned in a pBluescript SK II plasmid. DNA sequence of the cloned DNA was determined and submitted to the GenBank (accession number EU678363). Phylogenetic analysis of the ITS 1 DNA showed close similarity with the other plant species of the family Compositae. The extract of the plant materials of five different members of the family Compositae was analyzed by HPLC to detect atractylon. Extract of the A. japonica Koidz showed presence of significant amount of atractylon. However, noticeable amount of atractylon was not detected by the same analyses from the extracts of the other plants belonging to the family Compositae including Artemisia capillaris, Chrysantemum zawadskii, Eclipta prostrata or Taraxacum platycarpum.

Objectives: Type 2 diabetes mellitus is a metabolic disease characterized by insulin resistance and high blood glucose level from progressive insulin secretory defect. The rhizome of Atractylodes japonica Koidz. (AJ) has been used for treatment of retention of water in oriental medicine. The aim of this study is to examine the effects of AJ on type 2 diabetes rats. Methods: Type 2 diabetes was induced by 60% high fat diet and low dose streptozotocin. Rats were divided into 4 groups (n = 6); Nor (normal control group), Con (diabetic group treated with vehicle), Met (diabetic group treated with 200 mg/kg metformin) and AJ (diabetic group treated with 100 mg/kg AJ). The body weights and food intakes were measured during the treatment period. After 4 weeks treatment, blood glucose level, HOMA-IR, and protein expressions of IRS-1, p-IRS-1, PPAR-${\gamma}$, and GLUT4 were measured, and histopathological examination of beta cell was performed. Results: Compared with the control group, blood glucose level and HOMA-IR were reduced in rats treated with AJ. Impaired beta cells in pancreas of rats were recovered and phosphorylation of IRS-1 was increased in rats treated with AJ. And also, protein expressions of PPAR-${\gamma}$ and GLUT4 were increased by treatment of AJ. Conclusions: The results suggest that Atractylodes japonica Koidz. may have anti-diabetic effect on type 2 diabetic rats through regulation of blood glucose level and insulin resistance. Therefore Atractylodes japonica Koidz. may have positive effects on patients with type 2 diabetes.

Atractylodes japonica and Atractylodes macrocephala belongs to Atractylodes genus and theirs roots are used as 'Baek-chul'(White atractylodes rhizome) in Korea Pharmacopoeia. 'Baek-chul' widely used in traditional herbal remedies in Asia. Concurrently, the 'Baek-chul' demand enormously increased in the market due to the growing interest in favoring health benefits but it is depend on import from China. Thus we conducted breeding research to solve the problems associated with domestically cultivated 'Baek-chul' such as low productivity and low disease tolence. We crossed A. japonica (female parent) and A. macrocephala (male parent) in the greenhouse in September 2000. the next season 119 crossed line seeds were collected and germinated in the green house. Among them we selected the good lines in the same season. then conducted replicated yield trials (RYT) in 2014 to local adaptability test (LAT) in 2015-2016. The results showed that the 'AJM16' line has beneficial charactersitcs like, increased plant height, large rhizome diameter, narrow leaf width compared with a 'Sang-chul' (check cultivar) and varied flower color from A. japonica (female parent). The line 'AJM16' was also exhibited decreased anthracnose symptoms(Colletotrichum gloeosporides Penz.). Simultaneously the root yield of AJM16 was 2,409 kg per are, which was increased 130% higher yield compared to 'Sang-chul' (check cultivar) at three various regions from 2015 to 2016. Therefore, we named AJM16 as new cultivar 'Man-chul'. According the results, we have developed a new Atractylodes spp. hybrid cultivar 'Macn-chul' with high yielding and disease tolerance by National Institute of Horticulture and Herbal Science, RDA, in 2016.

Methanol extracts of the roots of Atractylodes japonica (alba) (Compositae) and Gentiana scabra (Gentianaceae) were further fractionated with n-butanol, chloroform, n-hexane and water. Then each fraction was p.o. administered to an animal model of hepatitis caused by $CCl_4$ intoxication. Measurements of sleeping time of mice induced by hexobarbital administration indicated that n-butanol and chloroform fractions of Atractylodes japonica (alba), and chloroform and n-hexane fractions of Gentiana scabra showed significant liver protective activities. Measurements of the activities of serum transaminase, S-GOT and S-GPT appeared to support these results.

Antiproliferative activity of the ethanol extract of Atractylodes japonica rhizomes (AJEX) was investigated using methyl thiazolyl tetrazolium (MTT) assays with various cancer cell lines (HL-60, MCF-7, SK-Br-3, MDA-MB-453, HepG2, Hep3B, PC-3, LNCaP, MKN 28, MKN 45, and HT-29 cells). Gastric carcinoma cell lines were the most responsive in terms of cell proliferation. The $IC_{50}$ of MKN 28 and MKN 45 cells were 35.98 and 27.57 ${\mu}g/mL$, respectively. Moreover, gastric carcinoma cells exposed to AJEX underwent apoptosis, as determined by Annexin V binding assay. Compared to respective control level, exposure to the AJEX at each $IC_{50}$ concentration resulted in a remarkable increase in the shift of cell populations. Present results suggest that AJEX possess potential anticancer properties.

Objectives : To determine the discriminative criteria for Atractylodes rhizomes, the experiment of externalinternal characteristics and physicochemical pattern analysis were performed. Methods : External characteristics was observed using stereoscope. The sectioned materials which were covered with parffin were stained by Ju's method. Physicochemical patterns were analyzed using HPLC/DAD. Results : 1. External shape of original plant : Atractylodes maaocephala and A. japonica had relatively long petioles and 3-5 parted leaves. A. macrocephala had big purple flowers whereas A. japonica had relatively small white flowers and pinnate bracts. A. lancea had sessile leaves and white flowers, and the end parts of degenerated stamens were bent. 2. External shape of herbal medicine: A. macrocephala which was fist-shaped rhizome had pa-pillate processes and the cross section was light gray and sulcate. A. japonica and A. lancea were connected-beady or tubercular rhizomes, and the cross sections were both yellow-colored white. However, the cross section of A. japonica was fibrous, the width of cortex was narro-wer than that of stele, and radial shape in cortex was rare, whereas the width of cortex in A. lancea was similar to that of stele in size, and radial shape in cortex was obvious. 3. Internal shape of herbal medicine: A. macrocephala and A. lancea did not have lignified fascicles in cortex. However, the vascular bundles and vessels of A. macrocephala were wedge shaped and radial arrangement, and vascular bundles were densely populated in stele whereas those of A. lancea were repeatedly arranged and thinly extended to cortex. A. japonica had lignified fascicles in cortex and the width of vascular bundles was conspicuously thick with narrow intervals. 4. Physicochemical pattern analysis : A. macrocephala and A. lancea contained atractylenolide I and atractylenolide Ill whereas A. japonica contained atractylenolide I, atractylenolide Ill. diacetyl-atractylodiol, compound-4, compound-5. The three species of Atractylodes rhizomes showed different chromatogram patterns. Conclusions : The results could be used as discriminative criteria for Atractylodes rhizomes and as fundamental materials to researches of further pattern analysis and biological reaction.
