우리 나라 전역에서 수집한 7종의 자생 둥굴레로부터 genomic DNA을 추출한 후 Operon random primer(10-mer)를 이용하여 PCR을 수행하여 재현성이 있으면서 polymorphism을 보이는 19개의 primer를 선발하였다. 선발한 primer로부터 PCR에 의해 증폭된 DNA의 크기는 $3000{\sim}300\;bp$이었고, 19개의 random primer에서 복제된 전체 band의 수는 114개에서 157개로 공시종간에 많은 차이를 보였으며, band의 유무에 근거한 유연관계 분석에서 7개의 공시종은 각시둥굴레와 층층둥굴레가 1개군으로, 여타 종들을 1개군으로 크게 2개군으로 분리되어 유전적으로 상당한 차이가 있는 것으로 나타났다.

This study investigated the in vivo insulin function of Polygonatum odoratum in normal and diabetic male Sprague-Dawley rats. Diabetes mellitus was induced by an i.p. injection of streptozotocin. Normal and diabetic rats were assigned to the diet groups of the control basal diet and Polygonatum odoratum diet. The animals were fed the diet and water ad libitum for 15 days. Initial and final body weights, total food intake and serum glucose and insulin levels were measured. An insulin suppression test was performed to elucidate the insulin function in the peripheral tissues. The results showed that the final serum glucose levels significantly decreased in the diabetic rats on the Polygonatum odoratum diet compared with the diabetic rats on the control diet. The final serum insulin levels were increased in the diabetic rats on the Polygonatum odoratum diet compared with the diabetic rats on the control diet. The in vivo function of the insulin increased in the diabetic rats on the Polygonatum odoratum compared with the diabetic rats on the control diet. These data indicate that Polygonatum odoratum may be beneficial in improving the in vivo insulin function in streptozotocin-induced diabetic rats.

Objectives : This study was designed to examine the effects of Polygonatum odoratum EtOH ext. on lowering lipid and anti-oxidation using hyperlipidemic rat. Methods : Male rats weighting $195.21{\pm}4.93g$ were divided into 4 groups and fed high fat diet for 8 weeks. Each of 7 rats was divided into a control and sample group. We fed a control group of rats a basal diet and administered normal saline(100 mg/kg, 1 time/1 day) for 4 weeks. And we fed each experimental group of rats basal diet and administered an extract of Polygonatum odoratum(100 mg/kg, 200 mg/kg, 300 mg/kg, 1 time/1 day) for 4 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. We measured lipid of plasma and liver, concentration of anti-oxidative activity and tumor necrosis factor-$\alpha$($TNF-{\alpha}$). Results : 1. Concentration of plasma free fatty acid, low density lipoprotein-cholesterol showed a significant decrement in the 200 mg/kg and 300 mg/kg Polygonatum odoratum EtOH ext. groups than that of control group. Concentration of plasma total cholesterol, triglyceride showed a significant decrement in all Polygonatum odoratum EtOH ext. groups than that of control group. However, concentration of plasma high density lipoprotein-cholesterol was not significantly different in all the treatment groups. 2. Concentration of liver total cholesterol showed a significant decrement in the 200 mg/kg and 300 mg/kg Polygonatum odoratum EtOH ext. groups than that of control group. Concentration of liver triglyceride(TG) showed a significant decrement in all Polygonatum odoratum EtOH ext. groups than that of control group. 3. Concentration of plasma thiobarbituric acid reactive substance, and liver thiobarbituric acid reactive substance showed a significant decrement in the 200 mg/kg and 300 mg/kg Polygonatum odoratum EtOH ext. groups than that of control group. 4. The values of glutathione peroxidase activity showed a significant increment in all Polygonatum odoratum EtOH ext. groups than that of control group. The values of superoxide dismutase activity and catalase activity showed a significant increment in the 200 mg/kg and 300 mg/kg Polygonatum odoratum EtOH ext. groups than that of control group. 5. The values of plasma aspartate aminotransferase and alanine aminotransferase activities were not significantly different in all treatment groups. 6. Concentration of liver $TNF-{\alpha}$ showed a significant decrement in the 200 mg/kg and 300 mg/kg Polygonatum odoratum EtOH ext. groups than that of control group. Conclusions : Based on the results in this study, the Polygonatum odoratum EtOH ext. showed a positive effect in lowering lipid and anti-oxidation.

The genus Polygonatum species belongs to the family Liliaceae which is widely distributed over areas of the north temperature zone. There are about forty more plants of Polygonatum species in the world widely distributed in eastern Europe and south east Asia. The plants of Polygonatum species have been used not only as ornamental plants but also for their medicinal values. This article is concerned with the specific properties and flavour of the drug and its history as a medicine, showing the main functional components of Polygonatum species of flavonoids, steroidal glycosides, and saccharides.

The hypoglycemic and hypotensive effects of Polygonatum odoratum in non-insulin dependent diabetes metlitus (NIDDM) patients were investigated in this study. Sixty five NIDDM patients were divided into two groups: hospital diet (HD), Polygonatum odorat um diet (PD). HD group was provided with the diabetic diet used in a hospital and PD group consumed the Polygonatum odoratum added to the HD. The index of obesity, the level of fasting blood pressure (systolic and diastolic), fasting and postprandial blood glucose of NIDDM patients of the PD group were significantly lowered after the experimental period of 4 weeks. The levels of the plasma glucose, lipid and index of obesity was measured. The tendency of elevating the level of HDL-cholesterol and lowering the levels of triglyceride, LDL-cholesternl and total cholesternl were also noticed in NIDDM patients of the PD group. The results showed that Polygonatutn odoratum could be an important dietary source to control hyperglycemia and hypertension and that the plant could be recommended as a preventive or therapeutic agent for NIDDM patients.

Inhibition of cancer-associated fibroblasts (CAFs) may improve the efficacy of cancer therapy. Polysaccharide extracted from polygonatum can selectively inhibit the growth of prostate-CAFs (p<0.001) without inhibiting the growth of normal fibroblasts (NAFs). Polysaccharides from polygonatum stimulate autophagy of prostate-CAFs. 3-methyl-adenine(3-MA) is an autophagy inhibitor. 3-MA was added to prostate-CAFs with polysaccharide from polygonatum to determine whether autophagy plays an important role in the restrained effect. Finally, polysaccharide from polygonatum treatment significantly increased the activation of Beclin-1 and LC3, key autophagy proteins. Polysaccharide from polygonatum stimulates autophagy of prostate-CAFs and inhibits prostate-CAF growth, indicating that a novel anti-cancer strategy involves inhibiting the growth of prostate-CAFs.

새 번식방법 개발을 위해 둥굴레 뿌리는 눈이 없어도 부정아가 발생된다는 점에 착안하여 뿌리길이와 굵기에 대한 부정아 발생에 관한 시험 연구를 한 결과는 다음과 같다. 1년차는 뿌리길이가 5cm 경우 66.5%지만 15cm에서는 113% 부정아 발생되었고, 뿌리의 굵기 5mm이하는 98.3%지만 10mm이상은 113.3%로 46.7% 차이를 보였다. 2년차는 부정아 생성률은 15cm에서는 1년차의 3배, 시험구 설치 당시 전혀 눈이 없는 상태에서 4배의 증식을 보였다. 용토는 일반토양 2.6배 보다 모래나 펄라이트가 3.1~3.3배 증식 되었다. 대량번식을 위한 가장 좋은 방법은 10mm 둥굴레 뿌리를 5cm로 절단하여 모래에 식재하는 방법으로 판단된다.

An HPLC/Esl/MS method has been developed to identify and quantify the spirostanol glycosides in the rhizomes of five Polygonatum species. The relative distribution of two steroidal saponins in each extract was established using the selective ion monitoring (SIM) mode via an electrospray ionization (ESI) source. It was found that there were significant differences in the amount of spirostanol glycosides among the Polygonatum Species. The results showed that this method could be used to identify the steroidal saponins in the extracts and differentiate Polygonatum species with high sensitivity and reproducibility in a short time. Fragmentation patterns of the two reference compounds were also discussed with the electrospray ionization multi-stage tandem mass spectroscopy (ESI-MS$^n$).
