This study was conducted to investigate the effect of the Platycodi radix powder (PRP) and Platycodi radix saponin(PRS) on the reduction of lipid status In rats fed on high fat diet for 6 weeks after which lipid contents were measured in liver. And also by carrying out the histological examination throughout light microscope to observe the effects of fat accumulation reduction. The results obtained from this study are as fellows. In the levels of total lipid in liver, PRS Group significantly decreased compared with Contred Group, but PRP Group was not significantly changed. The content of triglyceride was tended to be slightly decreased in the PRP and PRS groups compared to the control group, which was not significant. It was observed from photomicrographs of hepatic tissue in rats that the PRP and PRS groups inhibits the lipid accumulation induced by high fat diets.

Oxygen free radicals are highly reactive molecules with unpaired electrons, which are produced with in aerobic cells in the course of normal metabolic events. Normally, aerobic cells are protected from the damage of free radicals by antioxidative enzymes such as superoxide dismutase (SOD), catalase, glutathione (GSH) peroxidase, GSH S-transferase and GSH reductase which scabvenge free radicals as well as nonenzymatic antioxidants such as ceruloplasmin, albumin and nontioxidants in order to elucidate antioxidative mechanisms of red ginseng. The treatment with total saponin of red ginseng significantly devreased the contents of malondialdehyde and total free radicals in the liver. On the other hand, total saponin of red ginseng significantly increased the activities of SOD, catalase and GSH reductase and nonprotein-SH level. These results suggest that total saponin of red ginseng exerts an antioxidative effect by increasing endogenous antioxidants.

This study was conducted to elucidate the effects of light intensity using polyethylene (p.E) net shading on the specific gravity, red ginseng quality, sugar and saponin contents of ginseng root. The specific gravity significantly increased in the ginseng roots grown under the P.E net shading as compared with that of common straw shading. The red ginseng quality under the P.E net shading was improved in order of 10, 5, 15, 20, 30% of light intensity and the inside cavity and inside white part decreased remarkably as compared with those of common straw shading. The ginseng roots grown under the P.E net shading at 10% and 15% light intensity showed a significant increase in the total sugar content but a significant decrease in the reducing sugar content at 15% light intensity as compared with those of common straw shading. The amount of total saponin of ginseng roots was increased under the P.E net shading at high light intensity as compared with that of common straw shading and the ginseng roots grown under the P.E net shading at 10% light intensity showed an increase in the diol group saponin but the ratio of PT/PD was decreased. Extract contents of ginseng root under the P.E net shading was higher than those of common straw shading and the roots grown under the P.E net shading at 15% and 20% light intensity resulted in a remarkable increase in extract contents.

금산 및 음성지역의 4년생 인삼재배 농가포장에서 직파재배 5개소와 이식재배 5개소를 임의로 선정하여 직파와 이식재배에 따른 생육특성 및 엑스와 조사포닌 함량을 비교한 결과는 다음과 같다. 직파재배는 4년근 생존율이 평균 48%로 이식재배의 86%보다 떨어지나 입모수가 평균 96주/3.3$m^2$순로 이식재배의 57주보다 많고 엽면적지수가 커 수량성이 높은 반면, 주당근중은 작았다. 직파재배는 이식재배에 비해 동체의 신장이 양호하나 지근의 발달이 불량하여 동체중의 비율이 높고 지근중의 비율이 낮았으며, 직파재배는 적변 발생율이 적으나 동체와 지근부위의 엑스와 조사포닌 함량이 낮았다.

식물조직배양기술을 이용하여 사포닌 함량이 높은 인삼 root를 생산하고자, 인삼 root의 생장과 사포닌생산에 미치는 배지와 식물생장조절물질의 영향을 조사하였다. 인삼 root를 여러 종류의 배지에 배양하였을 때, 인삼 root의 생장과 사포닌 생산은 SH배지에서 가장 우수하였고, SH배지에 배양시, 접종후 약 10일후에 생체중량이 초기접종량의 2배가 되었다. 각 배지별로 배양한 인삼 root의 진세노사이드 패턴과 함량은 다소 차이가 있었는데, SH배지와 White배지에서 성장한 인삼 root의 총진세노사이드 함량이 가장 높았다. 생장조절물질에 있어서는 4.0mg/L NAA를 함유한 SH배지에서 성장한 인삼 root의 생장이 가장 우수하였고, 사포닌 함량은 0.5mg/L BAP 처리구에서 가장 높았다. 이러한 결과들은 인삼 root 배양에 의해 사포닌을 단기간에 생산할 수 있는 가능성을 제시하고 있다.

To find the monthly variation of kalopanaxsaponin contents in the leaves of Kalopanax pictus with thorns (KPT) and with no thorns (KPN), the leaves monthly collected from May to September were extracted with MeOH and then the kalopanaksaponin fractions were prepared. KPT collected on May showed the lowest saponin content of the KPTs whereas KPT on August exhibited the highest saponin content. From September, the saponin content in the loaves decreased. The highest saponin content was shown to be 7.3% in KPN collected on August. Evaluation of six kalopanaxsaponins A, I, J, B, H and K (KPA, KPI, KPJ, KPB, KPH, and KPK) were performed using TLC densitometer. In this measurement, considerably higher KPB and KPH, both hederagenin bisdesmosides, were found whereas very low contents In monodesrnosides KPI and KPJ were observed. In conclusion, it was shown that the leaves of KPN of August could be a biomaterial source for the kalopanaxsaponin fraction. It was also suggested that measurement of the weight of kalopanaxsaponin fraction and the content of KPB as the representative compound for kalopanaxsaponins will be used for the quantitative evaluation of the kalopanaxsaponins of K. pictus.

This study was conducted to assess the response of LED (Light-emitting diode) irradiation on the growth characteristics and saponin contents of Panax ginseng C. A. Meyer. LED irradiation showed a positive effect for most of the parameters studied. The content of chlorophyll a in leaves was increased by 4.9$\sim$36.5%, under LED and fluorescent light conditions compared to the control. The content of chlorophyll b was also increased by 44.4$\sim$55.6% under blue and red LED compared to the control except under the red plus blue LED condition. The shoot and root weight were increased by $20\sim60%$ and $14.8\sim59.3%$, respectively under LED and fluorescent light conditions compared to the control. The total saponin content was increased by 1.8% under blue LED compared to the control, while total saponin content was decreased by 8.8$\sim$11.5% under red LED, red plus blue LED and fluorescent light conditions.

Background: Panax quinquefolius and Panax notoginseng are widely used and well known for their pharmacological effects. As main pharmacological components, saponins have different distribution patterns in the root tissues of Panax plants. Methods: In this study, the representative ginsenosides were detected and quantified by desorption electrospray ionization mass spectrometry and high-performance liquid chromatography analysis to demonstrate saponin distribution in the root tissues of P. quinquefolius and P. notoginseng, and saponin metabolite profiles were analyzed by metabolomes to obtain the biomarkers of different root tissues. Finally, the transcriptome analysis was performed to demonstrate the molecular mechanisms of saponin distribution by gene profiles. Results: There was saponin distribution in the root tissues differed between P. quinquefolius and P. notoginseng. Eight-eight and 24 potential biomarkers were detected by metabolome analysis, and a total of 340 and 122 transcripts involved in saponin synthesis that were positively correlated with the saponin contents (R > 0.6, P < 0.05) in the root tissues of P. quinquefolius and P. notoginseng, respectively. Among them, GDPS1, CYP51, CYP64, and UGT11 were significantly correlated with the contents of Rg1, Re, Rc, Rb2, and Rd in P. quinquefolius. UGT255 was markedly related to the content of R1; CYP74, CYP89, CYP100, CYP103, CYP109, and UGT190 were markedly correlated with the Rd content in P. notoginseng.

수광율의 차이가 인삼엽내의 saponin과 유리당함량 및 Panaxatriol(PT)/Panaxadiol(PD) 비에 미치는 영향을 구명코자 수광량이 자연광의 5, 10, 20, 30%의 수광율(LTR) 하에서 자란 4년생 인삼엽에서 이들을 조사하였던 바 그 결과는 다음과 같다. 1. Ginsenoside별 함량은 PD계 사로닌에서는 -Rd가 가장 많았고, PT계 사포닌에서는 -Re, $Rg_1$, $-Rg_2$순으로 많았다. 2. Total 사포닌과 PT계 사로닌함량과 PT/PD의 비는 20% LTP까지 수광율이 많을수록 증가되다가 30% LTR에서는 약간 감소되었고, PD계 사포닌 함량은 수광율이 증가할수록 많아졌다. 3. Glucose, Fluctose 함량은 20% LTR에서 가장 많았으나 sucrose함량은 오히려 20% LTR에서 가장 적었다. 4. Total 사포닌 함량과 Glucose함량간에는 정(+)의 상관($r=0.992$^{**}$)이 인정되었다.
