연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

본 연구는 국내에서 소비되는 약용작물 중 경제적 가치는 높으나 국내 생산량이 적고 수입 의존도가 높은 Atractylodes의 식물 조직 배양 시스템을 구축하기 위해 수행되었다. 삽주는 A. ovata를 사용하였고, 4가지 cytokinins류, 6-benzylaminopurine (BA), zeatin, kinetin, thidiazuron (TDZ)을 2가지 농도(0.5, 1.0 mg/L)로 처리하였다. 4가지 유형의 cytokinin 중 BA처리는 A. ovata의 신초유도와 뿌리 생육에 효과적이었다. 0.5 mg/L 및 1.0 mg/L BA 모두 BA 처리에서 유사한 결과를 나타내었지만 1.0 mg/L BA가 신초와 뿌리 생육을 촉진하는데 더 효과적이었다. 처리 중 신초의 개수와 뿌리의 생중량(FW)을 제외하고는 TDZ 처리가 신초와 뿌리생육에 효과적이지 않아 본 수종에서는 적합하지 않았다. 본 연구에서는 A. ovata의 아배양을 이용한 기내증식 시스템을 구축하였다. 위 결과는 기내 재분화를 이용한 산림약용자원 A. ovata의 안정적인 생산 및 증식을 위한 기반 기술로 사용될 것으로 사료된다.

A new coumarin glycoside and a new glycoside of an acetylene derivative were isolated from the water-soluble portion of the methanolic extract of Atractylodes ovata rhizome together with eight known compounds. Their structures were characterized as scopoletin β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside and (2E)-2-decene-4,6-diyne-1,8-diol 8-O-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside, respectively, based on chemical and spectroscopic investigations. A comparison of the polar constituents among Atractylodes japonica, Atractylodes lancea, and A. ovata is led to the conclusion that A. ovata is distinguishable from A. lancea and A. japonica, as also shown by phylogenetic analysis.

The rhizome of Atractylodes ovata De Candolle is rich in essential oils, which are usually removed by processing. In this study, anti-oxidative abilities of essential oils and aqueous extracts of A. ovata rhizome were explored, and the influence of processing on the anti-oxidative abilities was examined. Essential oils and aqueous extracts of A. ovata were extracted by boiling water and steam distillation, respectively. Quality of these two A. ovata samples was controlled by HPLC and GC-MS system, and anti-oxidative abilities were then evaluated. Results showed that surface color of A. ovata turned to brown and chemical components were changed by processing. Contents of both atractylon and atractylenolide II decreased in the essential oils, but only the contents of atractylon decreased by processing. Atractylenolide III increased in both A. ovata samples. However, A. ovata essential oils displayed stronger anti-oxidative abilities than aqueous extracts in DPPH-scavenging, TBH-induced lipid peroxidation and catalase activity assays. Moreover, the bioactivity of essential oils from raw A. ovata was stronger than oils from processed A. ovata. On the other hand, cytotoxicity of A. ovata essential oils was stronger than that of aqueous extracts, and was more sensitive on H9C2 cell than NIH-3T3 and WI-38 cells. In contrast, stir-frying processing method increased cytotoxicity of essential oils, but the cytotoxicity was ameliorated when processed with assistant substances. The results suggested that phytochemical components and bioactivity of A. ovata were changed after processing and the essential oils from raw A. ovata showed better anti-oxidative and fewer cytotoxicity effects.

The rhizome of Atractylodes ovata (Bai Zhu in Chinese) is a widely used traditional Chinese herb in Taiwan as a tonic agent. In this paper, four sesquiterpenoids, namely atractylon, and atractylenolides I, II, and III, were isolated from the n-hexane extract of A. ovata and were evaluated for cytotoxic effects in vitro. Atractylon significantly inhibited the growth of human leukemia cell line HL-60 and mouse leukemia cell line P-388, and showed low cytotoxicity against primary cultures of normal human peripheral blood mononuclear cells at 15 microg/ml for 12 h. Atractylon had a dose-dependent antiproliferative effect on the two tumor cell lines. In accordance with DNA fragment increases and PARP protein decreases, atractylon at 15 microg/ml for 6 h induced apoptosis in HL-60 cells. Moreover, atractylon inhibited the viability of P-388 cells and induced apoptosis after 15 microg/ml treatment for 12 h in an in vitro assay. However, atractylenolide I at 30 microg/ml for 12 h also induced apoptosis in HL-60 and P-388 cells, but atractylenolides II and III showed no significant inhibition effects on tumor cell growth. As the above results suggested, atractylon and atractylenolide I were the major cytotoxic principle constituents of A. ovata on leukemia cell lines.

Atractylodes ovata (Compositae) shoot cultures were put into cold storage and the regenerated plants then evaluated. All the in vitro shoot cultures of A. ovata DC. survived cold storage at 2°C for up to 24 months. The cold-stored shoots were then multiplicated and rooted under normal culture conditions. The regenerated plants were cultivated in the field for one or two years and various biological and biochemical characteristics were compared with a control plant. Statistical analysis of the data showed no significant differences between the two groups in most morphological traits and the contents of the atractylon, a sesquiterpene component of essential oil in the rhizome. These results demonstrate that non-frozen cold storage of in vitro shoot cultures can be used as a germplasm preservation system for short-or medium-duration without deterioration of their biological and biochemical characteristics.

The genus, Colletotrichum is a prominent pathogen responsible for inducing anthracnose in various crops. The outbreaks of this disease typically observed from mid-June to mid-September in ovate-leaf atractylodes (sapchu) field. Manifesting as varying leaf symptoms, ranging from small dots to large lesions. The possible Colletotrichum spp. associated with anthracnose were isolated, and identified based on morphological and molecular characteristics. Molecular analysis includes multiple genes sequencing and the construction of a phylogenetic tree. 1) The result of anthracnose pathogen species identification (morphological and molecular analysis) revealed three complexes within the Colletotrichum genus. There were four species (C. fructicola, C. gloeosporioides, C. siamense, and C. cigarro) belonging to the C. gloeosporioides species complex, and two species (C. sojae and C. plurivorum) belonging to the C. orchidearum species complex. Only one species has been identified in the C. magnum species complex, C. ovataense is described as a new species here, and the other six Colletotrichum spp. had not been reported as the causal agent of ovate-leaf atractylodes in South Korea. 2)All the identified Colletotrichum spp. exhibited morphological variations such as spore size, ascospore size, and the color, shape, and size of approsoria. Notably, conidia size differed significantly compared to the species isolated from other plants. 3) All the Colletotrichum spp. were able to induced disease in wound inoculation, with variations in virulence levels. Colletotrichum fructicola, C. gloeosporioides, and C. cigarro produced symptoms on leaves under both unwounded and wounded conditions. In contrast, C. ovataense, C. plurivorum, C. siamense, and C. sojae manifested symptoms exclusively on leaves with wound. The size of lesions caused by C. gloeosporioides was the largest, and C. fructicola, C. gloeosporioides, and C. cigarro exhibited a 100% infection rate. 4) The effect of temperature on mycelial growth was varied between anthrachnose pathogen species at temperatures ranging from 15℃ to 35℃. The maximum growth rate of C. gloeosporioides was 20℃-25℃, and that of C. plurivorum and C. ovataense was 25℃. Species belonging to the C. gloeosporioides species complex had slow mycelial growth at high temperatures. 5) Regarding the effect of the medium on anthrcahnose pathogen mycelial growth, PDA, Corn meal agar, and Malt extract agar mediums supported good mycelial growth. 6) Fungicide sensitivity, as measured by the EC50 value inhibiting 50% of mycelial growth, differed significantly between Colletotrichum spp. and fungicide types. Azoxystrobin exhibited higher EC50 values for all seven species compared to other fungicides, with C. siamense displaying the lowest senestivity. Carbendazim had the lowest EC50 values for all species, ranging from 0.014 to 0.039㎍/㎖, while tebuconazole showed highest EC50 values with the range of 0.28 to 2.06㎍/㎖. 7) As a result of investigating the sensitivity standard concentration for each type of anti fungal chemical against the anthrachnose pathogen, Carbendazim fungicides had the highest EC50 value of 1.05㎍/㎖. 8) There was a significant difference in EC50 values in terms of spore germination rates for each type of fungicides and each type of pathogen. Carbendazim fungicide showed the lowest efficacy in C. fructicola and C. siamense with high EC50 values. 9) A two-year field investigation on efficacy of fungicide against ovate-leaf atractylodes (sapchu) anthracnose in the field demonstrated that all fungicides showed a control effect of more than 80%.
