Objectives : A morphological classification among Adenophora triphylla var. japonica, Codonopsis lanceolata, Adenophora remotiflora and Codonopsis pilosula was made through microscopic observation. Method : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by olymphus-BHT. Result : 1. Codonopsis pilosula is like a long cone, with amole-like projected parts at the beginning of the roots. 2. Adenophora triphylla var. japonica, Codonopsis lanceolata, Adenophora remotiflora, and Codonopsis pilosula are all similar as following: 1) Cork layers are composed of a few to over 10 subsidiary cells, with individual or a group of stone cells among them. 2) Phloem is wide and has a milk tube. Conclusion : Adenophora triphylla var. japonica, Codonopsis lanceolata, Adenophora remotiflora, and Codonopsis pilosula are all similar and difficult to be distinguished through microscopic observation, so that chemical experiments should be conducted for their identification.

Adenophora triphylla var. japonica extract has been reported to have estrogenic activity and beneficial effects in postmenopausal women requiring estrogen replacement therapy. This study investigated the effects of A. triphylla extract on cognitive function in ovariectomized mice. Water extracts from A. triphylla were administrated to ovariectomized mice fed a high fat diet for 6 weeks. The step through latency time in the passive avoidance test was shortened in ovariectomized mice as compared with sham-operated mice. However, administration of A. triphylla extracts had a tendency to prolong the latency time in ovariectomized mice. Moreover, A. triphylla supplementation caused a significant decrease in mean escape latency in the water maze test. These results indicate that A. triphylla could be used to improve estrogen deficiency-related learning and memory impairments in postmenopausal women.

Background: Adenophora triphylla var. japonica is empirically used for controlling airway inflammatory diseases in folk medicine. We evaluated the gene expression and production of mucin from airway epithelial cells in response to lupenone, lupeol and taraxerol derived from Adenophora triphylla var. japonica. Methods: Confluent NCI-H292 cells were pretreated with lupenone, lupeol or taraxerol for 30 minutes and then stimulated with tumor necrosis factor ${\alpha}$ (TNF-${\alpha}$) for 24 hours. The MUC5AC mucin gene expression and production were measured by reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay, respectively. Additionally, we examined whether lupenone, lupeol or taraxerol affects MUC5AC mucin production induced by epidermal growth factor (EGF) and phorbol 12-myristate 13-acetate (PMA), the other 2 stimulators of airway mucin production. Results: Lupenone, lupeol, and taraxerol inhibited the gene expression and production of MUC5AC mucin induced by TNF-${\alpha}$ from NCI-H292 cells, respectively. The 3 compounds inhibited the EGF or PMA-induced production of MUC5AC mucin in NCI-H292 cells. Conclusion: These results indicated that lupenone, lupeol and taraxerol derived from Adenophora triphylla var. japonica regulates the production and gene expression of mucin, by directly acting on airway epithelial cells. In addition, the results partly explain the mechanism of of Adenophora triphylla var. japonica as a traditional remedy for diverse inflammatory pulmonary diseases.

The purpose of this study was to investigate the action mechanism of the roots of Adenophora triphylla var. japonica extract (ATE) in 3T3-L1 adipocytes. Cell toxicity test by MTT assay and lipid accumulation was performed to evaluate the inhibitory effect on the differentiation of adipocyte from preadipocytes induced by MDI differentiation medium, while adipogenesis related proteins expression level were evaluated by western blotting. As a result, ATE inhibited MDI-induced adipocyte differentiation in 3T3-L1 cells dose-dependently without cytotoxicity. Our results showed that ATE inhibited the phosphorylation of IRS1, thereby decreasing the expression of PI3K110α and reducing the phosphorylation of AKT and mTOR, resulting in attenuated protein expression of C/EBPα, PPARγ, ap2 and FAS in 3T3-L1 cells. These results suggest anti-adipogenic functions for ATE, and identified IRS1 as a novel target for ATE in adipogenesis.

잔대(Adenophora triphylla var. japonica)의 뿌리는 비만, 암, 염증을 예방하는 데 사용되는 귀중한 약용 자원으로 사용되지만, 어린잎이나 순은 식재료로 사용되고 있다. 본 연구에서는 A. triphylla 뿌리와 잎에서 얻은 70% 에탄올 추출물의 항산화 및 항암 효과를 비교 평가하였다. 잎 추출물이 뿌리 추출물보다 강력한 DPPH-radical 소거 활성, 환원력 및 ORAC 값을 나타냈다. 또한, 인체 암세포주에서 잔대 추출물의 세포독성 사멸 효과를 조사한 결과, 잎 추출물이 A549 (폐암), LNcaP (전립선암), SKOV3 (난소암) 및 Caco-2 (대장암) 세포에서 강력한 항암 성분의 공급원임을 보여주었다. 이러한 결과는 뿌리뿐만 아니라 잎도 제약 산업에서 기능성 소재의 귀중한 공급원이 될 수 있음을 시사한다.

Asthma is an increasing global health problem, and novel strategies to prevent or ameliorate the condition are needed. The purpose of the present study was to evaluate the anti-inflammatory and anti-asthma effects of Adenophora triphylla var. japonica extracts. We investigated the molecular mechanism underlying the effects of 80% ethanol extracts (AE) of A. triphylla on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. AE treatment inhibited pro-inflammatory cytokines such as TNF-${\alpha}$ and IL-6 as well as nitric oxide (NO) production in LPS-stimulated RAW 264.7 cells. In particular, NO and pro-inflammatory cytokine production was suppressed more effectively by aerial parts (AE-A) than roots (AE-R) of A. triphylla. Quantitative RT-PCR assay showed that AE reduced mRNA levels of iNOS and COX-2. We also evaluated the anti-asthmatic effects of AE-A in an ovalbumin (OVA)-induced BALB/c mouse model. AE-A supplementation significantly reduced the amounts of airway eosinophils, IL-4 and IL-13 levels in BALF, and IgE levels in serum as compared with untreated, OVA-induced mice. These results suggest that AE-A can be considered as a therapeutic agent to potentially relieve asthma.

50여개의 primer를 사용하여 잔대 Adenophora triphylla와 층층잔대 A. radiatifolia Nakai, 그리고 더덕 Codonopsis laceolata Trautv의 지역간, 속간의 차이점과 감별여부를 RAPD법으로 시행한 결과, 잔대와 층층잔대의 차이점은 거의 없었으며, 더덕의 지역차이는 0.889의 유전적거리를 나타내었다. 두 종(種)을 구별할 수 있는 특이 band로는 primer 357, 361, 363, 393 이었으며, 건조약재와 비교하였을 때 재현성이 확인되었고, 또한 잔대와 더덕의 건조약재를 각각 혼합시켰을 때 이를 구별할 수 있는 major band가 뚜렷이 나타나 혼용되어있는 건조약재에서의 감별이 가능함을 알 수 있었다..

Background: Adenophora triphylla var. japonica (Regel) H. Hara shows vegetative growth with radical leaves during the first year and shows reproductive growth with cauline leaves and bolting during the second year. In addition, the shape of the plant varies within the same species. For this reason, there are limitations to classifying the species by visual examination. However, there is not sufficient genetic information or molecular tools to analyze the genetic diversity of the plant. Methods and Results: Approximately 34.59 Gbp of raw data containing 342,487,502 reads was obtained from next generation sequencing (NGS) and these reads were assembled into 357,211 scaffolds. A total of 84,106 simple sequence repeat (SSR) regions were identified and 14,133 primer sets were designed. From the designed primer sets, 95 were randomly selected and were applied to the genomic DNA which was extracted from five plants and pooled. Thirty-nine primer sets showing more than two bands were finally selected as SSR markers, and were used for the genetic relationship analysis. Conclusions: The 39 novel SSR markers developed in this study could be used for the genetic diversity analysis, variety identification, new variety development and molecular breeding of A. triphylla.
