본 연구에서는 새로운 전처리를 통한 홍삼을 제조하여 홍삼의 향취미의 변화를 살펴보았으며 이로써 맛과 향이 개선 된 홍삼제품을 개발하고자 하였다. Acid(ascorbic acid, citric acid) 감압침투 방법으로 산처리 홍삼을 제조하였으며, 반 건조 산처리 홍삼과 반건조 홍삼의 색, 유리당, ginsenoside 함량, 관능검사를 실시하였다. 홍삼분말 색은 산을 처리하면 밝기 (L)와 황색도 (b)도는 감소하며, 적색도 (a)는 증가하는 것으로 나타났다. Fructose, glucose는 산을 처리하지 않은 홍삼이 가장 높았으나 sucrose, maltose는 citric acid 처리한 홍삼이 높게 나타나는 것을 알 수 있었다. Ginsenoside 함량은 산을 처리한 홍삼에서 $Rg_2+Rh_1$, $Rg_3$의 함량이 증가 되는 것을 알 수 있었다. 산을 처리한 반건조 홍삼과 일반 반건조 홍삼 관능검사에서는 색과 단맛에서만 유의적 차이가 나타났다. 그러나 건조 홍삼 추출물을 관능 검사한 결과 쓴맛과 떫은맛, 신맛, 향취, 색의 강도에서는 유의적 차이가 나타났다. 특히 산 처리한 홍삼 추출물은 쓴맛과 떫은맛이 감소되어 산으로 전 처리한 홍삼은 인삼에 대한 거부감을 줄일 수 있는 제품으로 사용 가능성을 보여 주었다.

Ginseng (the root of Panax ginseng C. A. Meyer, Araliaceae) has been used for traditional medicine in China, Korea, Japan and other Asian countries. It is most often used as a general tonic, and it involves a wide range of pharmacological actions, such as antiaging, adaptogen-like effect to foreign deleterious infringement, immunoenhancement, antistress, antitumor, and antioxidant actions. Red ginseng showed anticarcinogenic activity against various chemical carcinogens in mouse and cancer-preventive effect of human being as on mice in experimental and epidemiological studies. In the present study, we have found the protective properties of red ginseng against vinyl carbamate (VC) which is the proximate carcinogen of ethyl carbamate and its ultimate carcinogenic epoxides. Red ginseng exhibited dose-dependent inhibition on the mutagenci activities of boty VC in the presence of S9 mix and vinyl carbamate epoxide (VCO) without metabolic activation in Salmonella typhimurium TA1535. Formation of DNA adducts from VCO was also attenuated in the presence of red ginseng. Oral administration of red ginseng prior to the topical application of each of the above carcinogens and TPA treatment resulted in significant reduction in both incidence and multiplicity of skin tumors in mice. These results indicate that red ginseng possesses a strong chemopreventive effect against mouse skin carcinogenesis induced by VC or VCO.

Background: Red ginseng extract boosts immunity against inflammation and cancer in the human body. However, studies on the effects of red ginseng extract on the gut microbiome remain unexplored. Methods: In 2019, the positive effects and changes in the gut microbiome after administering 1 pack (3 g) of red ginseng extract per day to 53 adults aged 40 to 75 for 24 weeks were investigated. The gut microbial environment changes were qualitatively and quantitatively analyzed using next-generation sequencing and real-time polymerase chain reaction technology. Results: On comparing and analyzing alpha diversity and beta diversity, the microbial pattern showed significant differences (OTUs p = 0.003, chao1 p < 0.001, Bray-Curtis p = 0.001) before and after ingestion of red ginseng extract, indicating that gut microbial richness increased after ingestion. Moreover, after comparing and analyzing the gut microbiome's differences after red ginseng extract intake, significant differences were noted between three strains at the phylum level and among 57 strains at the genus level. Conclusion: This study proposes the potential use of red ginseng extract as a prebiotic after confirming its positive effects, including increasing gut microbiome richness, reducing harm to the gut microbiome, and increasing the number of some strains in the gut microbiome.

Background: White ginseng consists of the roots and rhizomes of the Panax species, and red ginseng is made by steaming and drying white ginseng. While red ginseng has both polar and nonpolar ginsenosides, previous studies showed white ginseng to have only polar ginsenosides. Because nonpolar ginsenosides are formed through the manufacture of red ginseng from white ginseng, researchers have generally thought that nonpolar ginsenosides do not exist in white ginseng. Methods: We developed a simultaneous quantitative method for six nonpolar ginsenosides in white ginseng using reverse-phase high-performance liquid chromatography coupled with integrated pulsed amperometric detection. The nonpolar ginsenosides of white ginseng were extracted for 4 h under reflux with 50% methanol. Results: Using the gradient elution system, all target components were completely separated within 50 min. Nonpolar ginsenosides were determined in the rhizome head (RH), main root (MR), lateral root, and hairy root (HR) of 6-year-old white ginseng samples obtained from several regions (Geumsan, Punggi, and Kanghwa). The total content in the HR of white ginseng was 37.8-56.8% of that in the HR of red ginseng. The total content in the MR of white ginseng was 5.9-24.3% of that in the MR of red ginseng. In addition, the total content in the RH of white ginseng was 28.5-35.8% of that in the HR of red ginseng Conclusion: It was confirmed that nonpolar ginsenosides known to be specific components of red ginseng were present at substantial concentrations in the HR or RH of white ginseng.

This clinical study was performed to evaluate whether supplementation of proton pump inhibitor (PPI)-based triple therapy with Korean red ginseng can enhance Helicobacter pylori (H. pylori) eradication and reduce levels of halitosis-associated volatile sulfur compounds (VSCs) in the stomach. Seventy-six patients were randomized into an eradication regimen-only group (n=45) or an eradication regimen plus 10 weeks of Korean red ginseng supplementation group (n=31). The eradication regimen consisted of PPI b.i.d., clarithromycin 500 mg b.i.d., and amoxicillin 1 g b.i.d.. for seven days. Korean red ginseng supplementation commenced on the last day of the eradication regimen. $^{13}C$-urea breath test and halimeter measurements were performed prior to protocol repetition. By intention-to-treat analysis, the H. pylori eradication rate in the Korean red ginseng group (77.4%, 24 of 31) was higher than that in the control group (45.0%, 26 of 45). However, by per protocol analysis, the eradication rate in the Korean red ginseng group was significantly higher than that in the control group (92.3%, 24/26 vs. 69.4%, 26/38; p<0.05). H. pylori infection was significantly associated with increased VSC levels. However, VSC levels decreased significantly in the Korean red ginseng group (p<0.05). In conclusion, supplementation of triple therapy with Korean red ginseng increased the H. pylori eradication rate and led to significant reductions in VSC levels, suggesting the usefulness of this substance in combating H. pylori infection.

This study was carried out to investigate the optimum conditions for extraction of acidic polysaccharides from red ginseng marc produced by manufacturing alcoholic extract from red ginseng. Method of carbazole-sulfuric acid was applied to determine the amount of acidic polysaccharides in red ginseng marc. The amounts of acidic polysaccharides in water extract of red ginseng marc were increased with increasing extraction temperature. The contents of acidic polysaccharides were not significantly different despite of the extraction time increasing from 6 hours to 48 hours. The contents of starch in water-extract of red ginseng marc were increased with increasing extraction temperature. The starch amounts in water extract of red ginseng marc extracted for 48 hours were increased. The yields of polysaccharide precipitated from water-extract of red ginseng marc were increased with increasing extraction temperature. The hydration rate of acidic polysaccharides and starch from water-extract of red ginseng marc were decreased with increasing extraction temperature. The contents of starch were not significantly different despite of the extraction time increasing from 6 hours to 48 hours at $8^{\circ}C$. However, the rehydration rate of acidic polysaccharide for 48 hours were decreased at $8^{\circ}C$. The rehydration rate of acidic polysaccharide and starch extracted from 6 hours to 24 hours at $25^{\circ}C$ were not significantly different, but those extracted for 48 hours were increased. From the above results, we suggest that by altering the extraction conditions in red ginseng marc it is possible to develop optimum conditions for extraction that modulate the proportions of acidic polysaccharide and starch.

Panax ginseng, a medicinal plant, has been used as a blood-nourishing tonic for thousands of years in Asia, including Korea and China. P. ginseng exhibits adaptogen activity that maintains homeostasis by restoring general biological functions and non-specifically enhancing the body's resistance to external stress. Several P. ginseng effects have been reported. Korean Red Ginseng, in particular, has been reported in both basic and clinical studies to possess diverse effects such as enhanced immunity, fatigue relief, memory, blood circulation, and anti-oxidation. Moreover, it also protects against menopausal symptoms, cancer, cardiac diseases, and neurological disorders. The active components found in most Korean Red Ginseng varieties are known to include ginsenosides, polysaccharides, peptides, alkaloids, polyacetylene, and phenolic compounds. In this review, the identity and bioactivity of the non-saponin components of Korean Red Ginseng discovered to date are evaluated and the components are classified into polysaccharide and nitrogen compounds (protein, peptide, amino acid, nucleic acid, and alkaloid), as well as fat-soluble components such as polyacetylene, phenols, essential oils, and phytosterols. The distinct bioactivity of Korean Red Ginseng was found to originate from both saponin and non-saponin components rather than from only one or two specific components. Therefore, it is important to consider saponin and non-saponin elements together.

In this paper, we present evidence that the red ginseng from Panax ginseng C.A. Meyer inhibits the recurrence of advanced gastric cancer and shows immunomodulatory activities during postoperative chemotherapy. Flow cytometric analyses for peripheral T-lymphocyte subsets showed that the red ginseng powder restored CD4 levels to the initial preoperative values during postoperative chemotherapy. Depression of CD3 during postoperative chemotherapy was also inhibited by the red ginseng powder ingestion. This study demonstrated a 5-year disease free survival and overall survival rate that was significantly higher in patients taking the red ginseng powder during postoperative chemotherapy vs. control $(68.2\%\;vs.\;33.3\%,\;76.4\%\;vs.\;38.5\%,$ respectively, p<0.05). The mean value of serum IL-10 of the ginseng group was reduced progressively during the postoperative chemotherapy. The values of the ginseng group were close to that of the control group on postoperative months 3. These studies suggest that the red ginseng may have some immunomodulatory properties associated with CD3 and CD4 activity and interleukin 10 during postoperative chemotherapy and some potential of improving prognosis in patients with advanced gastric cancer.
