Objectives : The researcher investigated the anti-obesity effect of Platycodi Radix (P), Platycodi Radix and Cyperi Rhizoma combination water extract (PC) in mice fed a high fat diet and focused on the analysis of local area adipose tissue.Methods : Male ICR mice were divided into four groups, which were fed either a normal AIN diet (N group), a high fat diet (HFD group), or a high fat diet and orally administration with a concentraion of 300 mg/kg body weight (P group or PC group) for eight weeks.Results : Compared to mice in the HFD group, mice in the P group or PC group showed significant reductions in weight gain and relative weight of total fat. Compared to mice in the HFD group, mice in the P group showed significant reductions in relative weight of liver. In blood biochemistry analysis, AST, ALT, triglyceride, total-cholesterol and low density lipoprotein(LDL)-cholesterol, AI levels of P group or PC group were significantly lower than those of the control group AI. But serum serum high density lipoprotein(HDL)-cholesterol levels from the P group or PC group were significantly higher than those of the HFD mice in serum. And serum adiponectin levels from the P group or PC group were significantly increased that those of the HFD mice. And adipocyte number in the fat tissue from the P group or PC group was significantly higher than those of the HFD mice.Conclusions : Platycodi Radix, Platycodi Radix-Cyperi Rhizoma have an anti-obesity effect in mice and the effect is mediated by inhibition of fat gain.

The objective of this study is to find the effect of improving hyperlipidemia through Platycodi radix saponin. A hypercholoesterol diet and Platycodi radix saponin methanol extract were supplemented to the 6 week old male Spargue Dawley rats for four weeks. Results showed that the serum total cholesterol, triglyceride and LDL-cholesterol level decreased in the group supplemented with Platycodi radix saponin methanol extract(p<0.05), however, the serum total lipid and HDL-cholesterol did not show any difference from the control group according to the supplement of Platycodi radix saponin methanol extract. In the group supplemented with Platycodi radix saponin methanol extract, the total cholesterol decreased by 20%, triglyceride by 36% and LDL-cholesterol by 25% respectively, and there was no difference according to the level of Platycodi radix saponin methanol extract. AI(atherogenic index) and CRF(cardiac risk factor) were low in the group supplemented with Platycodi radix saponin methanol extract. Total lipid, total cholesterol and triglyceride in liver and feces were significantly low in the group supplemented with the Platycodi radix saponin methanol extract compared with the control group(p<0.05). According to this result, it is expected that the Platycodi radix saponin methanol extract supplemented in the hypercholesterol diet can lower atherosclerosis, the cause of cardiovascular disease, by reducing not only serum cholesterol and triglyceride but also liver cholesterol and triglyceride.

The extract of Platycodi radix has long been used as an anti-inflammatory traditional medicine in Korea for the treatment of bronchitis, asthma and acute respiratory disease. In this study, the anti-inflammatory actions of the methanol extract of Platycodi radix administered via oral administration were evaluated. The results revealed that the extracts exhibited potent anti-inflammatory action. Of the hexane, chloroform, ethyl acetate, butanol and water fractions, the butanol fraction had the most potent anti-inflammatory action. Additioinally the sapogenin obtained through acid hydrolysis of the butanol fraction did not show anti-inflammatory action. These findings confirm the value of Platycodi radix as a traditional Korean medicine.

Background : Nowadays asthma is considered to be the inflammatory disease characterized by airway hyperresponsiveness and pulmonary eosinophilia, and mediated by Th lymphocytes expressing the Th2 cytokine pattern. In many recent studies, molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of asthma. Objective : We aimed to identify the effect of Armeniacae Arnarum Semen and Platycodi Radix on the transcriptional activities of cytokine IL-4, IL-5 and IL-6 involved in asthma model. Materials and Methods : RBL-2H3 cell lines were used. Cells were stimulated with calcium inophore for maximal gene expression. After 24 hours of Armeniacae Arnarum Semen and Platycodi Radix-treatment, total cellular RNAs were collected using Trizol solution method. Then transcriptional activities of IL-4, IL-S and IL-6 were measured by RT-PCR with electrophoresis. Results : In IL-4 study, Armeniacae Arnarum Semen treated group showed 48.4% of transcriptional activities compared to the control group and Platycodi Radix treated group showed 45.4% of transcriptional activities compared to the control group. In IL-5 study, Armeniacae Arnarum Semen treated group showed 52.7%of transcriptional activities compared to the control group and Platycodi Radix treated group showed 60.2% of transcriptional activities compared to the control group. In IL-6 study, Armeniacae Amarum Semen treated group showed 42.3% of transcriptional activities compared to the control group and Platycodi Radix treated group showed 69.1% of transcriptional activities compared to the control group. Conclusion : This study shows that Armeniacae Arnarum Semen and Platycodi Radix have the inhibitory effect on the transcription of IL-4, IL-5 and IL-6 gene expression in RBL-2H3 cell lines. Advanced studies are required to investigate the mechanisms of inhibition by herbal medicine in asthma model.

This study was conducted to examine the development of a new anti-inflammatory substance with potent anti-inflammatory activities that was derived from the Platycodi Radix butanol fraction. To accomplish this, the chemical structures and anti-inflammatory activities of the components were elucidated. Upon column chromatography of the tertiary subfraction, fractions 8-4-1 and 8-4-2 were identified as platycodin D and D3, respectively, following recrystallization, based on melting point (MP), infrared (IR), and positive fast atom bombardment (FAB)-mass and nuclear magnetic resonance (NMR) spectral data. Platycodin D and D3 exhibited strong anti-inflammatory activities in rats when administerd at oral doses of 12 mg/kg and 36 mg/kg, p.o., respectively. Platycodin D and D3 induced inhibitory effects on capillary vascular permeability in rats at oral doses of 16 mg/kg and 24 mg/kg, p.o., respectively, and potent inhibition of leukocyte emigration in a carboxymethyl cellulose (CMC)-pouch when administered at doses of 3 mg/rat and 7 mg/rat, s.c., respectively. These results verified the high antiinflammatory potency of the platycodin D and D3 components in Platycodi Radix.

전통 한의학에서 많이 사용되는 길경(Platycodi radix)은 도라지(Platycodon grandiflorum A. DC)의 뿌리 껍질을 벗기거나 또는 그대로 말린 것을 말하며, 염증성 호흡기 질환에 많이 사용되어져 오고 있다. 본 연구에서는 길경 수용액 추출물의 항암 활성 기전해석의 일환으로 A549 인체 폐암세포의 성장에 미치는 영향을 조사하였다. 길경 추출물의 처리에 의하여 처리 농도 의존적으로 암세포의 성장이 억제되었으며, 이는 apoptosis의 유발과 관련이 있었다. 즉 염색체 응축에 의한 apoptotic body의 출현과 sub-Gl기에 속하는 세포의 빈도가 길경 추출물 처리에 의하여 농도 의존적으로 증가하였다. Immunoblot 및 RT-PCR분석에서 길경 추출물의 처리에 의하여 Bcl-2의 mRNA 및 단백질의 발현은 감소되었으며, Bax의 발현이 증가됨을 알 수 있었다. 또한 길경 추출물의 처리에 의하여 caspase-3가 활성화되었으며, 이에 따른 PARP 및 $\beta$-catenin의 단백질 발현 감소 현상을 관찰할 수 있었다. 이러한 결과들은 길경 추출물을 이용한 인체 암세포의 성장억제제의 개발 가능성이 있음을 시사하여 준다.
