Panax ginseng has long been used as a traditional herbal medicine. More recently, it has received attention for its anti-diabetic and anti-obesity effects in humans and in animal models of type 2 diabetes. In the present study, we tested the hypoglycemic effects of ginseng berry extract in beta-cell-deficient mice and investigated the mechanisms involved. Red (ripe) and green (unripe) berry extracts were prepared and administered orally (100 or 200 mg/kg body weight) to streptozotocin-induced diabetic mice daily for 10 wk. The body weight was measured daily, and the nonfasting blood glucose levels were measured after 5 and 10 wk after administration. Glucose tolerance tests were performed, and the serum insulin levels were measured. The proliferation of beta-cells was measured in vitro. The administration of red or green ginseng berry extract significantly reduced the blood glucose levels and improved the glucose tolerance in beta-cell deficient mice, with the higher doses resulting in better effects. Glucose-stimulated insulin secretion was significantly increased in berry extract-treated mice compared with streptozotocin-induced diabetic control mice. Treatment with ginseng berry extract increased beta-cell proliferation in vitro. Both red berry and green berry extracts improved glycemic control in streptozotocin-induced diabetic mice and increased insulin secretion, possibly due to increased beta-cell proliferation. These results suggest that ginseng berry extracts might have beneficial effects on beta-cell regeneration.

The purpose of this study is to develop a new preparation process of ginseng berry extracts having high concentrations of ginsenoside Rh1, Rg2, Rg5, F4, a special component of red and black ginseng. Chemical transformation from ginseng saponin glycosides to prosapogenin was analyzed by the HPLC. Extracts of ginseng (Panax ginseng) berry was processed under several treatment conditions including ultrasonication treatments. The content of total saponin reached their heights at 6 hr (UGB-6, 61.760%) of ultrasonication treatment, followed by 10 hr (UGB-10, 53.009%) and 9 hr (UGB-9, 50.652%) of ultrasonication treatment at $100^{\circ}C$. Results of those treatments showed that the quantity of ginsenoside Rh1 increased by over 15% at 10 hr of ultrasonication treatment at $100^{\circ}C$. The results of processing with UGB-10 indicate that the ultrasonication processed ginseng berry extracts that had gone through 10 hr treatments were found to contain the largest amount of ginsenoside Rh1 (15.358%), Rg2 (6.301%), Re (4.567%) and F4 (2.658%). In addition, UGB-6 contained ginsenoside Rg3 (13.632%) at high concentrations. It is thought that such results provide basic information in preparing ginseng berry extracts with functionality enhanced.

Background: Korean ginseng (Panax ginseng) plays an anti-inflammatory role in a variety of inflammatory diseases such as gastritis, hepatitis, and colitis. However, inflammation-regulatory activity of the calyx of the P. ginseng berry has not been thoroughly evaluated. To understand whether the calyx portion of the P. ginseng berry is able to ameliorate inflammatory processes, an ethanolic extract of P. ginseng berry calyx (Pg-C-EE) was prepared, and lipopolysaccharide-activated macrophages and HEK293 cells transfected with inflammation-regulatory proteins were used to test the anti-inflammatory action of Pg-C-EE. Methods: The ginsenoside contents of Pg-C-EE were analyzed by HPLC. Suppressive activity of Pg-C-EE on NO production, inflammatory gene expression, transcriptional activation, and inflammation signaling events were examined using the Griess assay, reverse transcription-polymerization chain reaction, luciferase activity reporter gene assay, and immunoblotting analysis. Results: Pg-C-EE reduced NO production and diminished mRNA expression of inflammatory genes such as cyclooxygenase-2, inducible NO synthase, and tumor necrosis factor-${\alpha}$ in a dose-dependent manner. This extract suppressed luciferase activity induced only by nuclear factor-${\kappa}B$. Interestingly, immunoblotting analysis results demonstrated that Pg-C-EE reduced the activities of protein kinase B (AKT)1 and AKT2. Conclusion: These results suggest that Pg-C-EE may have nuclear-factor-${\kappa}B$-targeted anti-inflammatory properties through suppression of AKT. The calyx of the P. ginseng berry is an underused part of the ginseng plant, and development of calyx-derived extracts may be useful for treatment of inflammatory diseases.

Ginseng is a popular medicinal plant highly valued throughout the world. Asian ginseng is one of the most common species of ginseng. It has long occupied a significant position in oriental medicine and has been justified its name as the 'king herb'. As a nutritional supplement, ginseng is an extremely common and popular herbal medicine in the United States and Canada in recent decades. The multiple constituents of ginseng possess equally multifaceted pharmacological actions as demonstrated by numerous studies. Ginseng root and its constituents influenced the central nervous system, endocrine, cardiovascular, gastrointestinal system, sexual, renal organ and immune system, etc. One important action is its anti-hyperglycemic effect. Previous studies on ginseng demonstrate that only the root of ginseng has been used in the treatment of diabetes, while the other parts of ginseng plant were always neglected. Recently, we analyzed the constituents of ginseng berry, leaf and discovered that ginseng berry, leaf extracts and its total ginsenosides have the ability to reduce hyperglycemia and body weight and increase the peripheral glucose utilization in obese or diabetic ob/ob or db/db mice. Our data suggest that all parts of ginseng plant, including root, berry, leaf and stem exhibit potent anti-hyperglycemic and anti-obese effects and may provide an opportunity to develop a novel class of anti-diabetic agents.

인삼은 건강에 효과적인 약초라고 알려져 왔다. 인삼의 열매인 진생베리는 인삼의 주성분과 비슷한 ginsenoside, saponin, polyphenol, polyacetylene, alkaloid 등의 성분을 포함한다. 본 연구의 목적은 인삼과 같이 진생베리 열수 추출물(Ginseng berry water extract, GBE)이 당뇨와 연관된 세포 외 효소와 인슐린 신호전달 경로에 있는 분자의 발현에 어떤 효과를 가지고 있는지를 조사하였다. ${\alpha}$-Amylase와 ${\alpha}$-glucosidase는 섭취한 다당분자를 분해하여 포도당을 생성함으로 항당뇨 약물개발의 표적 효소이다. GBE에 의한 두 효소의 활성 억제능을 in vitro에서 측정하였으나 최고 $1,000{\mu}g/ml$ 농도에서도 효소활성 억제능이 나타나지 않았다. 인슐린 신호전달 경로의 영향을 확인하기 위해서 HepG2 세포에서 GBE에 의한 인슐린 신호전달 경로의 주요 단백질인 protein-tyrosine phosphatase 1B (PTP1B)와 Akt1의 발현수준 변화를 Western blot 방법으로 조사하였다. 이때 인슐린에 의한 이들 분자의 변화에 GBE가 영향을 주는 것으로 나타났다. PTP1B는 인슐린에 의해 증가된 발현량이 저농도의 GBE이 의해 더욱 증가하였으나, $200{\mu}g/ml$ 농도의 GBE에 의해서는 다소 감소하는 것으로 나타났다. 또한, Akt1도 인슐린에 의해 증가된 발현량이 GBE 농도에 따라 감소하는 것으로 나타났다.
