  • 약용식물인 도꼬마리 추출물을 사용하여 유산균을 이용한 단일 및 복합배양을 통하여 새로운 기능성 물질의 생산을 검토하였다. 도꼬마리 추출물의 유산발효 시 단일배양 결과에서 유산생산을 통해 대체로 잘 증식하는 것이 확인되었으며, H. pylori의 항균 활성은 단일배양보다 복합배양 시 항균활성이 아주 우수하였다. 항균성 물질의 분리는 $C_{18}$ Seppak cartridge에 흡착시켜 30% methanol 용출획분에서 항균성물질이 확인되었으며, TLC로 분석한 결과 $R_f$ 0.46의 위치에서 항균성 물질을 확인하였다. 도꼬마리 유산발효액의 항산화활성은 총 polyphenol 함량 및 radical 소거능을 검토하였으며, 그 결과 총 polyphenol 함량은 미발효시에 비해 도꼬마리 추출물의 저농도에서 단일배양의 경우 2~4배 증가하였으며, Lactobacillus brevis KCTC 3498과 Lactobacillus helveticus KCTC 3545를 복합배양한 경우 1 mg/mL 첨가농도에서 polyphenol이 가장 높게 나타났다. Radical 소거능은 도꼬마리 추출물을 0.1 및 0.5 mg/mL로 첨가하여 발효하였을 때 30~40%의 scavenging이 확인되어 발효를 하지않았을 때 (25%)보다 발효를 하였을 때 높아지는 것으로 나타났다. 특히 Lactobacillus casei KCTC 3109의 경우 0.1 mg/mL의 농도에서 70%의 scavenging을 나타내었다. 이들 결과로부터 도꼬마리 추출물의 유산발효는 미발효시에 비해 Helicobactor pylori에 대한 항균활성물질의 생산과 기능성물질인 항산화물질의 생산성이 우수하다고 사료되었으며 천연한약재의 발효를 통한 천연물 신약 등 신기능물질의 생산가능성을 확인하였다.

  • Triphala churna is a widely used herbal formulation that contains equal proportion of dried fruit powder of Emblica officinalis, Terminalia chebula and Terminalia belirica. In the Indian system of medicine, it is used in cleaning wounds, urinary disorders, diabetes mellitus, leprosy, constipation, eyesight promotion, piles, and as a rejuvenator. In the present study, the methanolic extract of 5 commercial Triphala was evaluated for antioxidant activity by 1,1-diphenyl-2-picryl-hydrazyl free radical scavenging method, total phenolic content by Folin-Ciocalteu method and gallic acid equivalents (GAE) by high performance thin layer chromatographic (HPTLC) method. All extracts exhibited antioxidant activity significantly. The $IC_{50}$ of the extracts ranged between $7.16\;to\;12.96\;{\mu}g/ml$. The total phenolic content of the extracts was found to be 195.3-296.4 mg of GAE/gm of GAE/gm dw. The HPTLC chromatographic data reveal that the content of GAE present in the extract was found to be $7.17-4.11\;{\mu}g/ml$. The study reveals that out of the churnas analysed, C was found to exhibit the most potent antioxidant activity. A clear correlation between $IC_{50}$ and content of GAE nor the total phenolic content could be observed. The study reveals that the consumption of Triphala would exert several beneficial effects by virtue of its antioxidant activity.

  • Objectives : Hyangsapyungwisan (HPS) has been used for treatment of cardiovascular diseases including of arthralgia, myalgia in traditional Korean medicine. However, the medical actions of HPS have not been clearly investigated. The aim of this study was to elucidate the antiradical and antioxidant activity of the extract for herb-acupuncture (HPS-HA) obtained from HPS. Methods & Results : HPS-HA exhibited a stronger inhibition rate (55.5%) on lipid peroxidation of rat liver homogenate induced by $FeCl_2$-ascorbic acid. In addition, HPS-HA markedly interfered with hydroxylradical generation through iron ions chelating action. While pro-oxidant effect of HPS-HA was nearly undetectable at concentrations of 0.5-10㎎/mL. Moerover, HPS-HA revealed a potent antiradical activities on 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radicals, superoxide anions, nitric oxide and peroxynitrite. Furthermore, HPS-HA inhibited copper- and AAPH-mediated oxidation of human low-density lipoprotein (LDL), and also suppressed the relative electrophoretic mobility of LDL. HPS-HA showed strong protective activity against oxidative damage of HUVECs induced by SIN-1. Conclusions : These results suggest that HPS-HA may be effective in protecting against oxidative diseases.

  • Objectives : To develop a natural antioxidant and anti-hemolytic agents, we investigated the effects of ethanol extracts of Carpesii Fructus and Farfarae Flos. Methods : Aerial parts of Carpesii Fructus and Farfarae Flos were extracted with 80% ethanol. Antioxidant activity of Carpesii Fructus or Farfarae Flos extract was evaluated by employing three different assays, i.e., 1,1-diphenyl-2-picryl hydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzthiazoline-6-suphonic acid) diammonium (ABTS) scavenging and reducing power activities. Also, anti-hemolytic activity of Carpesii Fructus or Farfarae Flos extract was determined using [2,2'-azobis (2-methylpropionamidine) dihydrochloride (AAPH)]-induced hemolysis, glutathione (GSH) depletion and malondialdehyde (MDA) formation in normal rat red blood cells (RBC) or plasma. Results : The extracts obtained from Carpesii Fructus and Farfarae Flos dose-dependently increased the scavenging activity on DPPH- or ABTS-induced radicals and the reducing power activities. Carpesii Fructus and Farfarae Flos were similar to the scavenging activity and the reducing power of butylated hydroxy anisole effect at high concentration ($1,000{\mu}g/mL$). RBC oxidative hemolysis and plasma MDA formation induced by AAPH were significantly suppressed by the extracts of Carpesii Fructus and Farfarae Flos in a dose-dependent manner. Also, Carpesii Fructus and Farfarae Flos extracts prevented the depletion of cystosolic antioxidant GSH in RBCs. Carpesii Fructus generally had better than the free radical scavenging activity, the reducing power and anti-hemolytic effects of Farfarae Flos. Conclusions : These results suggest that Carpesii Fructus and Farfarae Flos may have value as the potential antioxidant and anti-hemolytic medicinal plant.
