천속단과 한속단은 명칭이 유사하여 '속단'으로 통칭하여 판매되고 있으나, 종과 속이 서로 다른 약재일 뿐만 아니라 함유 성분이 다르므로 주의가 필요하다. 천속단은 골격강화, 골절치료 작용이 있는 한약재로 식품원료로는 사용할 수 없으나, 한속단의 뿌리와 잎은 식품원료로 사용이 가능하다. 본 연구에서는 식품 중 천속단 혼입여부 판별을 위하여 LC-MS/MS를 이용한 동시분석법을 개발하였으며, 선택성, 직선성, 검출한계, 정량한계, 정확성, 정밀성을 검토하였다. 국내 유통중인 식품 중 어린이 키성장을 표방하는 제품 17건을 구매하여 천속단 혼입여부에 대한 실태조사를 하였다. 분석결과 17건의 시료 중 5건의 시료에서 천속단이 검출되었으며, 천속단 지표성분의 함량은 loganin $0.19-14.45{\mu}g/mL$, sweroside $0.13-4.61{\mu}g/mL$, akebia saponin D $0.59-19.29{\mu}g/mL$이었다. 본 연구에서 개발된 동시분석법은 식품 중 불법 혼입된 천속단을 간단하면서도 신속하게 판별하는데 도움이 될 것으로 사료된다.

Objectives : A root of Dipsacus asperoides C. Y. Cheng et T. M. Ai (D. asperoides) has been traditionally used as a medicinal resource in several Asian countries, including Korean and traditional Chinese medicine that has been traditionally used for treating several medical conditions including pain, arthritis, and bone fractures in Korea. In the present study, we investigated potential subacute toxicities of D. asperoides extract. Methods : C57BL/6 mice (male, 7weeks) were randomly divided into 4 groups of 5 mice. Except for the control group, the mice were orally administrated D. asperoides extract at doses of 50, 150, or 450 mg/kg/day for 2 weeks. At the end of the treatment period, all mice were euthanized, and the following parameters were examined: mortality, body weight, clinical signs, gross findings, hematology, serum biochemistry, organ weight, and histopathology. Results : There were no abnormalities in mortality, clinical signs, body weight, gross findings, or organ weight after repeated administration of D. asperoides extract for 2 weeks, compared with the control group. In addition, there were no significant changes in hematological, serum biochemical, and histopathological parameters between the control group and D. asperoides extract administrated groups with doses of up to 450 mg/kg/day. Conclusion : In this study, D. asperoides extract showed no significant toxicities at a dose of up to 450 mg/kg/day in mice. Although we could not confirm the toxic dose of D. asperoides extract, it can be considered safe for further pharmacological use.

Background: This study aimed to investigate the effect of harvest time on the growth, yield characteristics and loganin content in Dipsacus asperoides Wall. Methods and Results: Dipsacus asperoides seedlings were planted within a nursery environment in early May 2015 and harvested in early, middle and late October 2015, and early November 2015. Harvest time did not result significant differences in the plant height, stem diameter, branch length, leaf width and aboveground dry weight moreover, no significant differences were observed in root length, number of roots and root diameter. However, the diameter of lateral roots was greater in the harvests from the late October and period thereafter. The highest values of root dry weight and yield were recorded in early November. Specifically, the yield significantly increased from 205 kg/10 a (index: 100) in early October to 358 kg/10 a (index: 175) in early November, in terms of root part weight. Loganin contents of D. asperoides differed significantly among harvest times raging from 0.0766% in early October to 0.1704% in late November, thereby showing an increasing trend in later harvest times. Conclusions: These results suggest that the optimum harvest time for D. asperoides is early November, when the yield is the highest. Harvest time significantly affected loganin contents, which constantly increased from early October until early November.

As a result to amplifying 12 samples of 'Sok-dan' through an random amplified polymorphic DNA (RAPD) method using eighteen DEC and URP primers, distinct band forms enabling discrimination of Phlomus umbrosa and Dipsacus asperoides were observable in the UBC 320 primer, UBC 367 primer, UBC 385 primer, UBC 414 primer, UBC 423 primer, URP 3 primer, URP 5 primer and URP 9 primer. The polymorph result amplified with a random primer was evaluated through Gelcompar II, showing a result dividable into two groups. The divided groups were the dried sample group of Dipsacus asperoides and the group of Phlomis umbrosa. In order to recognize the distinction between Dipsaci Radix types, the genetic variation of 'Sok-dan' produced domestically and imported was evaluated through RAPD, and the potential to distinguish these in forms of dried medicine was identified, presenting a method to authentification of Phlomis umbrosa and Dispacus asperoides.

Objectives : This study aimed to review the change in the origin of Sokdan(續斷) by diachronically analyzing literature data from Korea and China. Methods : Literature records describing the origin(synonyms, location of production, description) of Sokdan were collected, records were divided into periods. The main contents were included in the results, and original texts were edited and summarized in the table. Results : Sokdan, whose leaves resemble Jeoma(苧麻)(SJ), was first recorded in 《Xinxiubencao(新修本草)》, and described in detail in 《Bencaotujing(本草圖經)》 during the Tang and Song dynasties in China. In modern times, SJ was assumed to be genus Phlomoides or Lamium; however, records of the plant have decreased. Finally, SJ was not included in the 《Pharmacopoeia of the People's Republic of China》 as Sokdan. However, 《Diannanbencao(滇南本草)》, 《Diannanbencaotushuo(滇南本草圖說)》, 《Zhiwumingshitukao(植物名實圖考)》 described Sokdan of dian(滇). It was assumed genus Dipsacus. From the 1950s onwards, Sokdan is described in the literature as a member of the genus Dipsacus. In korea, SJ was recorded in 《Hyangyakjipseongbang(鄕藥集成方)》 and 《Dongeuibogam(東醫寶鑑)》 during the Joseon dynasty. In modern times, the genera Phlomoides and Lamium were mostly recorded as the origin of Sokdan. Conclusions : Several species have been described as Sokdan over the years in China, but since the 1950s, the genus Dipsacus was noted as the origin of Sokdan. In Korea, SJ was used in the past, thus Sokdan was recorded as P. umbrosa in 《The Korean Herbal Pharmacopoeia(KHP)·1985》. However, 《KHP·1998》 referred to P. umbrosa as Hansokdan and D. asperoides as Sokdan.

Objectives : The object of this study was to verify the inhibitory effect of a decoction of Eucommiae ulmides OLIVER (EU) and Dipsacus asperoides C. Y. Cheng et T.M.Ai (DA) on Collagen II-induced Arthritis Mice (CIA mice). Methods : DBA/1OlaHsd mice were immunized with bovine type II collagen. Boostnig same collagen 21 days later, arthritis was induced and then administrated orally the extract of EU+DA (200 or 50 mg/kg) once a day for 4 weeks and compared with that of methotrexate (MTX, 0.3 mg/kg) as a positive control. Results : Administration of EU+DA suppressed the inflammatory progression of CIA mice and the results were 1. Arthritis index of CIA mice was decreased. 2. EU+DA decreased the production of TNF-$\alpha$, IL-6, IL-$1{\beta}$ in the serum of CIA mice. 3. EU+DA decreased the level of IgM. 4. EU+DAincreasaed $CD3^+$, $CD4^+$, $CD4^+$/CD25 but decreased $CD19^+$, $CD3^+/CD49b^+$(NKT), $CD3^-/CD49b^+$(NK), $B220^+/CD23^+$ in PBMC of CIA mice. 5. EU+DA decreased $CD3^+$, $CD4^+$, $CD3^+/CD69^+$ of paw joint in CIA mice. 6. EU+DA decreased subsynovial inflammation. Conclusions : This results demonstrated that extract of EU+DA suppressed the inflammatory progression of CIA mice and supported further studies are required to clarify a mechanism of therapeutic role.

Objectives : The roots of Dipsacus asper had been used as the herbal medicine "Cheon-Sokdan" in Korea. Moreover, the roots of Phlomoides umbrosa were used as "Han-Sokdan." In the present study, a comparative anatomical comparison of Cheon-Sokdan, Han-Sokdan, and Ilbon-Sokdan were conducted, because Ilbon-Sokdan, the roots of Dipsacus japonicus, was regarded as substitute of Cheon-Sokdan. Methods : For this study, permanent preparations were made using a paraffin embedding method. Anatomical features of these three Sokdans were observed using a light microscope. Results : The starch grains of parenchyma cells and the amounts of calcium oxalate crystals hardly differed among the three plants. Particularly, the longitudinally-sectioned vessels of the three plants showed a wide variety depending on the focal depth of the light microscope. Therefore, these features could not be considered as obligate criteria for distinguishing these plants. The shape of the xylem was linear in Cheon-Sokdan and Ilbon-Sokdan, whereas that in Han-Sokdan was wedge-shaped. The phloem of Cheon-Sokdan and Ilbon-Sokdan were rhomboid, whereas that of Han-Sokdan was thimble-like. Therefore, the shape of xylem and phloem appeared as good criteria for distinguishing Han-Sokdan from the other plants studied. Cheon-Sokdan and Ilbon-Sokdan showed characteristics similar in many parts. However, in the xylem of Ilbon-Sokdan, fiber bundles were more developed than those of Cheon-Sokdan. Therefore, the development of fiber bundles in xylem was considered suitable for distinguishing between Cheon-Sokdan and Ilbon-Sokdan. Conclusions : The identification-keys established in this study would be helpful for identifying microscopic features among the three Sokdans.
