        우슬을 주원료로 한 복합조성물의 기능성 평가

        권순성,최선강,주두권,이진원,신세철,최혜림,오영선,성은수 한국산업식품공학회 2019 산업 식품공학 Vol.23 No.2

        The antioxidant activity, total phenol content, and inhibitory effect of xanthine oxidase (XOase) for six different medicinal plant complexes such as Achyranthes japonica, Acanthopanax sessiliflorus, Carthamus tinctorius, Eucommia ulmides, Viscum album, and Caragana koreana were investigated in this study. The free radical scavenging activity values using DPPH(2,2'-diphenyl-1-picrylhydrazyl) and ABTS[2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radical cation] analyses were found to be 532.03±86.60 μg/mL and 1376.50±35.01 μg/mL, respectively, in 95% of ethanol extracts among six medicinal plant mixed compositions (6MPMC). The total phenolic content in 70% ethanol extract of 6MPMC was 125.19±1.34 mg GAE/g. The inhibitory activity against XOase was highest at 33.20±0.17% in the 70% ethanol extract of 6MPMC. In the antimicrobial activity test of 6MPMC, the minimum inhibitory concentration (MIC) value showed activities against V. litoralis and E. coli in 70% and 95% ethanol extracts, and these two microorganisms were created in clear zones by method of paper disc diffusion. These results suggest that the 6MPMC, composed of Achyranthes japonica, Acanthopanax sessiliflorus, Carthamus tinctorius, Eucommia ulmides, Viscum album, and Caragana koreana, have both antioxidant and antimicrobial activities and, therefore, may serve as a functional health food product.

      • Pediococcus pentosaceus로 발효된 황기 지하부가 인간 피부 섬유아세포의 콜라겐 생성에 미치는 효과

        이한나,고은지,최선강,유창연,성은수,임정대 한국약용작물학회 2018 한국약용작물학술대회 발표집 Vol.2018 No.05

        Background: This study were to investigate the effect of Pediococcus pentosaceus fermented Radix astragali (AMRP) and non-fermented products (AMRNP) on collagen synthesis in the cultures of human dermal fibroblasts, and their inhibitory effects on the matrix-degrading enzymes (collagenase, elastase, and gelatinase). Methods and Results: Both AMRP and AMRNP significantly improved cell growth and proliferation of HDF cells. However, the enzyme-linked immunosorbent assay and Western blot analysis demonstrated that AMRP, but not AMRNP, significantly and dose-dependently stimulated the biosynthesis of type I procollagen in both aged (74 y) and young (21 y) HDF cells. Real-time reverse transcription-polymerase chain reaction revealed that expression of type I, type III procollagen and transforming growth factor β1 (TGF-β1) mRNA was significantly stronger in AMRP-treated HDF cells than that of AMRNP-treated and un-treated HDF cells. The AMRP revealed an increase in astragaloside Ⅳ only depending on increase in fermentation period, because other astragalside converted to astragaloside Ⅳ, which it detached acyl group by fermentation processing of Pediococcus pentosaceus. Conclusion: The results also suggested that AMRP could stimulate the collagen biosynthesis in human dermal fibroblasts, which is, associated with the regulation of procollagen biosynthesis resulting from AMRP-induced TGF-β1 expression and the mitogenic activity in HDF cells, and therefore, is expected to reduce the age-dependent loss of extracellular matrix proteins.

        Background: The soft petiole of the Glehnia littoralis shoot is used as a raw material for food. It contains specific ingredients such as polyacetylene and coumarin. However, basic research considering their safety verification, efficacy, and ingredient identification is needed. Methods and Results: In this study, GC/MS compound profiling and LC/UVD were performed to evaluate the antioxidant activity of G. littoralis shoot extract fractions, and to identify the compounds contained therein. Total phenol and flavonoid content as well as antioxidant activity were maximum in the ethyl acetate layer, and a significant correlation was confirmed between total phenol content and antioxidant activity. GC/MS compound profiling, revealed a total of more than 40 compounds, and active ingredients such as coumarin-based phellopterin unique to G. littoralis and polyacetylene-based falcarinol (panaxinol) were qualitatively analyzed. The highest coumarin content was found in the ethyl acetate layer. Conclusions: In this study, the antioxidant activity and compounds contained in the shoot (soft petiole) fractions of G. littoralis were confirmed. These basic data may contribute to expanding the material value of G. littoralis in the future.

        과도 운동 후 면역능 개선에 미치는 황기 다당체의 효과

        이시영,이한나,고은지,박영철,최선강,유창연,임정대 한국약용작물학회 2018 韓國藥用作物學會誌 Vol.26 No.1

        Background: Polysaccharides are the most important functional constituent in Astragalus membranaceus. The purpose of the present study was to evaluate the effect of polysaccharides isolated from the aboveground parts of A. membranaceus (AMA) and polysaccharides isolated from the roots of A. membranaceus (AMR) immune function by modulated cytotoxic T cell and Th1- and Th2- related cytokines kinetics. Methods and Results: Sprague-Dawley rats were randomly divided into exhaustive exercise case groups and non-exercise case, AMA and AMR samples were administered orally for 30 days (500 ㎎/㎏/day and 10 ㎎/㎏/day, respectively) and were compared to those rats in the groups fed commercial sports drink (SPD) and vehicle. Both exhaustive exercise groups and non-exercise groups had a lower ratio of CD4+ and CD8+ cells in the spleens of the rat fed AMA and AMR compared to those in the rats fed SPD and vehicle group. These results suggested that AMA and AMR promote an increase in the proportion of cytotoxic T cells. The IL-4- producing T lymphocytes decreased significantly in the AMR (10 ㎎/㎏/day) group compared to SPD and vehicle, whereas the AMA group increased the IL-4 concentration more than the SPD and vehicle in exhaustive exercise group. However, the populations of IFN-γ-producing T lymphocytes of AMR and AMA increased. AMA decreased the concentration of IFN-γ to inhibit the Th1 response and thereby increased the concentration of IL-4 to induce a Th2 response that was related to humoral immunity in the non-exercise group. Conclusions: These results showed that, in addition to Th1/Th2 regulation, AMR and AMA played an important immuno-modulatory role after exhaustive exercise-induced Th1/Th2 lymphocyte imbalance, which might be correlated with cytokine producing immunoregulatory cells.

        Background: To obtain useful cosmetic resources, this study aimed to determine the non-saponin fatty acid and inhibitory activities of collagenase and elastase by treatment of Saccharomyces cerevisiae in supercritical fluid extracted oil of the adventitious root culture of wild mountain ginseng. Methods and Results: We performed supercritical fluid extraction at various conditions such as pressure, temperature, time, and use of co-solvents, unlike the n-hexane extraction for the adventitious roots culture of wild mountain ginseng. The non-saponin-fatty acid obtained from the oil of the adventitious roots culture was incresed by treatment with S. cerevisiae. The supercritical fluid extraction was conducted using gas chromatography. Non-saponin-fatty acid content, in the oil of adventitious roots culture of wild mountain ginseng treated with S. cerevisiae for 2 days were three times higher than that in the control. In addition, the oil of the adventitious roots culture treated with S. cerevisiae was investigated for the anti-wrinkle effect by using collagenase and elastase. The oil of adventitious roots culture treated with S. cerevisiae exhibited higher collagenase and elastase inhibitory activities than those in the control. Conclusions: Supercritical fluid extracted oil of the adventitious roots culture of wild mountain ginseng treated with S. cerevisiae was found to have decreased ratio of saturated fatty acids and incresed ratio and content of unsaturated fatty acids increased. Furthermore, it showed anti-wrinkle effects in vitro.

        Background: In recent years, adjuvants have received increasing attention owing to the development of purified subunit and synthetic vaccines which are poor immunogens and require additional adjuvants to evoke an immune response. Therefore, immunologic adjuvants have been developed and tested. Plant polysaccharides have been recognized as effective biological response modifiers with low toxicity.Methods and Results: In this study, the polysaccharide from the aboveground part of Astragalus membranaceus Bunge containing immunomodulating arabino-3,6-galactan was evaluated for its hemolytic activity and adjuvant potential in the specific cellular and humoral immune responses to ovalbumin. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge was co-immunized with the purified Vi capsular polysaccharide of Salmonella typhi vaccine in mice. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge did not induce any hemolytic activity or side effects at doses up to 500㎍/㎖. The concanavalin A-, lipopolysaccharide-, and ovalbumin-induced splenocyte proliferation and serum ovalbumin-specific IgG, IgG1 and IgG2b antibody titers in immunized mice were significantly enhanced by AMA. Pharmacological data revealed that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge increased antigen-specific antibody levels in immunized mice. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge-adjuvanted purified Vi capsular polysaccharide of Salmonella typhi vaccine improved the proliferation of splenocytes and macrophages as well as stimulated cytokine production.Conclusions: These results suggest that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge-adjuvanted vaccines enhanced humoral and cellular immunity and that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge is a safe and efficacious adjuvant candidate suitable for use in prophylactic and therapeutic vaccines.
