To exert their beneficial effects, it is essential for the commensal bacteria of probiotic supplements to be sufficiently protected as they pass through the low pH environment of the stomach, and effectively colonize the intestinal epithelium downstream. Here, we investigated the effect of a multilayer coating containing red ginseng dietary fiber, on the acid tolerance, and the adhesion and proliferation capacities of three Lactobacillus strains (Limosilactobacillus reuteri KGC1901, Lacticaseibacillus casei KGC1201, Limosilactobacillus fermentum KGC1601) isolated from Panax ginseng, using HT-29 cells, mucin-coated plates, and human pluripotent stem cell-derived intestinal epithelial cells as in vitro models of human gut physiology. We observed that the multilayer-coated strains displayed improved survival rates after passage through gastric juice, as well as high adhesion and proliferation capacities within the various gut epithelial systems tested, compared to their uncoated counterparts. Our findings demonstrated that the multilayer coat effectively protected commensal microbiota and led to improved adhesion and colonization of intestinal epithelial cells, and consequently to higher probiotic efficacy.

A wide range of studies have steadily pointed out the relation of oxidative stress to the primary and secondary causes of human disease and aging. As such, there have been multiple misconceptions about oxidative stress. Most of reactive oxygen species (ROS) generated from chronic diseases cause oxidative damage to cell membrane lipids and proteins. ROS production is increased by abnormal stimulation inside and outside in the body, and even though ROS are generated in cells in response to abnormal metabolic processes such as disease, it does not mean that they directly contribute to the pathogenesis of a disease. Therefore, the focus of treatment should not be on ROS production itself but on the prevention and treatment of diseases linked to ROS production, including types 1 and 2 diabetes, cancer, heart disease, schizophrenia, Parkinson's disease, and Alzheimer's disease. In this regard, Korean Red Ginseng (KRG) has been traditionally utilized to help prevent and treat diseases such as diabetes, cancer, inflammation, nervous system diseases, cardiovascular disease, and hyperlipidemia. Therefore, this review was intended to summarize in vivo animal and human clinical studies on the antioxidant activities of KRG and its components, ginsenosides.

백삼과 홍삼의 추출수율은 각각 33.56%와 48.79%로 홍삼의 추출수율이 높았고, 산성다당체의 경우 1~4차 추출단계까지는 홍삼군이 백삼군보다 높았으나, 5차 추출단계에서 백삼군이 6차 추출단계에서는 홍삼군이 높게 나타났다. 백삼과 홍삼의 추출단계별 농축액의 조사포닌 함량은 백삼(56.44 mg/g)에 비해 홍삼(53.15 mg/g)이 약 5.8 % 증가하는 것으로 나타났다. 이들을 혼합한 선택적 홍삼농축액 모델 4종의 기호도 평가 결과 1, 2, 6차 추출물이 혼합된 RGB-4가 가장 높은 기호도를 나타내었고 시판 홍삼 농축액 3종에 대해 비교한 결과에서도 RGB-4가 쓴맛, 떫은맛, 인삼향 강도가 약해지고 종합적 기호도에서 높은 평가를 받았다. 본 실험에서는 추출방법을 달리 함으로써 추출수율 및 조사포닌 함량을 감안하여 인삼 쓴맛과 향의 강도를 낮출 수 있다는 것을 확인하였다. 이 추출방법을 이용하여 쓴맛을 저감시키고 인삼향미의 강도를 저감시킨 제품을 개발하여 좀 더 편하고 자연스럽게 홍삼제품을 접할 수 있도록 더 많은 연구가 진행 되어야 할 것이다.

Korean ginseng (Panax ginseng C. A. Meyer) has been used as an important medicinal plant in the Orient for a long time. It has been claimed that ginseng has many beneficial bioactive effects on human health, such as antitumor, antistress, antiaging and enhancing immune functions. Red ginseng possibly have new ingredients converted during steaming and dry process from fresh ginseng. Kujeungkupo method which means 9 repetitive steaming and drying process was used for the processes of green tea, Polygonatum odoratum, and Rehmanniae radix preparata. In this study, ingredient conversion of ginseng by 9 repetitive steaming and drying process were investigated measuring conversion efficiency of brown materials, crude lipids, crude proteins and aromatic compounds. Brown materials, as an antioxidant, in red ginseng were produced through non-enzymatic reaction by heat. Repetitive steaming and drying treatments on ginseng root contiunously increased the content of brown materials and the chromaticity. Crude lipids were degraded by heat and converted into volatile aromatic ingredients. Crude lipids were degraded and decreased by 0.52% after the 5th and 7th. Crude proteins were also decomposed and converted to amino acid. Crude proteins after the 9th treatment were decreased by more than 85% as increased times of treatments. A bicyclogermacrene as aromatic material was decreased as increased treatment times, while but a aromatic caramel was increased.

Ginseng, the root of Panax ginseng CA Meyer, is well known as a tonic medicine for restoring and enhancing human health. In traditional medicine, ginseng is utilized for the alleviation of emesis, which includes nausea and vomiting. However, it has not yet been demonstrated whether ginseng exhibits in vivo anti-nausea and anti-vomiting properties. In this study, we examined the anti-emetic effect of Korean red ginseng total extract (KRGE) on cisplatin-induced nausea and vomiting using ferrets. Intraperitoneal administration (i.p.) of cisplatin (7.5 mg/kg) induced both nausea and vomiting with one-hour latency. The episodes of nausea and vomiting reached a peak after 1.5 h and persisted for 3 h. Treatment with KRGE via oral route significantly reduced the cisplatin-induced nausea and vomiting in a dose-dependent manner. The anti-emetic effect was 12.7 $\pm$ 8.6, 31.8 $\pm$ 6.9, and 67.6 $\pm$ 4.0$\%$ with doses of 0.3, 1.0, and 3.0 g/kg of KRGE, respectively. Pretreatment with KRGE via oral route 1 and 2 h before cisplatin administration also significantly attenuated the cisplatin-induced nausea and vomiting. However this did not occur with a pretreatment 4 h before cisplatin administration. These results are supportive of KRGE being utilized as an anti-emetic agent against nausea and vomiting caused by chemotherapy (i.e. cisplatin).

To evaluate the antiatopic effect of Korea red ginseng (RG, steamed root of Panax ginseng CA Meyer, Family Araliaceae) fermented by Bifidobacterium longum H-1 (FRG), its inhibitory effect on passive cutaneous anaphylaxis (PCA) reaction and itching in mice was measured. FRG and its ingredient saponin fraction (FSF) potently inhibited PCA reaction and scratching behaviors. FRG at a dose of 200 mg/kg and FSF at a dose of 50 mg/kg significantly inhibited the scratching frequency by 45% and 47%, respectively. FRG and FSF also inhibited the degranulation and protein expression of tumor-necrosis $factor-{\alpha}$ and interleukin-4 of RBL-2H3 cells induced by IgE-complex. However, polysaccharide fraction of FRG (FPF) weakly inhibited it, compared with FSF. The inhibitory effect of FRG against PCA reaction and scratching behaviors more potently inhibited than that of RG. Based on these findings, FRG can improve allergic skin disorders atopic dermatitis by the regulation of $TNF-{\alpha}$, and IL-4 produced by mast cells and basophils and its degranulation.

Lipid and fatty acid compositions of free lipids and bound lipids from fresh ginseng, red ginseng and white ginseng were studied by means of silicic acid column chromatography, thin-layer chromatography and gas-liquid chromatography. Free lipid and bound lipid contents in those three samples were 1.21 to 1.45% and 0.32 to 0.45%. Neutral lipid fractions in free lipids from the samples were 76.6 to 79.7%, while glycolipid and phospholipid fractions were 11.6 to 14.7% and 8.5 to 8.7%, respectively. The major lipids were triglycerides, sterol esters and hydrocarbons, diglycerides and free sterols in neutral lipids, sterol glucoside, monogalactosyl diglyceride, esterified steryl glycoside, digalactosyl diglyceride in glycolipids and phosphatidyl ethanolamine, phosphatidyl glycerol, phosphatidyl choline and phosphatidyl inositol in phospholipids. Fourteen kinds of even numbered and four kinds of odd numbered fatty acids were identified in the four lipid fractions (TL, NL, GL and PL) by GLC, and the main fatty acids were linoleic acid, palmitic acid, oleic acid and linolenic acid.

To evaluate the antiatopic effect of Korea Red Ginseng (RG, steamed root of Panax ginseng C.A. Meyer, Family Araliaceae), its inhibitory effect on passive cutaneous anaphylaxis reaction and itching in mice was measured. RG and its ingredient saponin fraction (SF) potently inhibited passive cutaneous anaphylaxis (PCA) reaction and scratching behaviors. RG at a dose of 100 mg/kg and SF at a dose of 50 mg/kg significantly inhibited the scratching frequency by 32% and 38%, respectively. RG and SF also inhibited the degranulation and protein expression of tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-4 of RBL-2H3 cells induced by IgE-antign complex. However, polysaccharide fraction of RG did not inhibit it. Based on these findings, RG can improve allergic skin disorders atopic dermatitis and contact dermatitis by the regulation of $TNF-{\alpha}$, and IL-4 produced by mast cells and basophils and their membrane stabilization.
