The flowers and buds of Lonicera Flower (LF), are used in Korean herbal medicine for latent-heat-clearing, antipyretic, detoxicant and anti-inflammatory ailments. This plant is used worldwide for the treatment of many types of inflammatory disease including respiratory infections, diabetes mellitus, rheumatoid arthritis and play an important role in immune reaction. These pharmaceutical effects of LF looks like to be related to its antioxidant capacity and phytochemicals containing in LF. In this study, the antioxidant activity of extract from LF was studied in vitro methods by measuring the antioxidant activity by TEAC, measuring the scavenging effects on reactive oxygen species (ROS) [superoxide anion, hydroxyl radical] and on reactive nitrogen species (RNS) [nitric oxide and peroxynitrite] as well as measuring the inhibitory effect on $Cu^{2+}$ induced human LDL oxidation and the inhibitory effect on collagen induced platelet aggregation. The LF extracts were found to have a potent scavenging activity, as well as an inhibitory effect on LDL oxidation and on platelet aggregation. In conclusion, the LF extracts have anti-oxidative and anti-atherosclerotic effects in vitro system, which can be used for developing pharmaceutical drug against oxidative stress and atherosclerosis.

Objectives The object of this study was to assess the effect of Gyejibokryunghwan (GBH) on anti-oxidant and anti-inflammatory activities in RAW 264.7 cells and on factors associated with fracture union in tibia-fractured rats. Methods The 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activity was measured to assess anti-oxidant activity. The production of nitric oxide (NO), interleukin-6 (IL-6), interleukin-$1{\beta}$ ($IL-1{\beta}$) and tumor necrosis factor-${\alpha}$ ($TNF-{\alpha}$) in the RAW 264.7 cells were measured to assess anti-inflammatory activity. The production of osteocalcin, calcitonin, carboxy-terminal telepeptides of type II collagen (CTXII), transforming growth factor-${\beta}$ ($TGF-{\beta}$), bone morphogenetic protein-2 (BMP-2) in serum of tibia-fractured rats were measured to assess the effects of fracture union. X-rays were taken every two weeks from 0 to 4th week to assess fracture union effect. Results DPPH radical scavenging activity of GBH was increased according to concentration of GBH in RAW 264.7 cell. NO, prostaglandin $E_2$ ($PGE_2$), IL-6, $IL-1{\beta}$ and $TNF-{\alpha}$ were significantly decreased, indicating anti-inflammatory effect. Osteocalcin, calcitonin, $TGF-{\beta}$ were significantly increased in the experimental groups. CTXII was significantly decreased in the experimental groups. BMP-2 was not significantly changed in the experimental groups. The X-ray showed that the experimental group has better healing effects on tibia-fractured rats than control group. Conclusions From above result, GBH has an effect on anti-oxidant, anti-inflammatory activities in RAW 264.7 cells. GBH showed significant results in factors related with fracture union and radiologic examination. In conclusion, GBH can help fracture union and it well be expected to be used actively in clinics.

There is currently increased interest in the identification of antioxidant compounds that are pharmacologically potent and have low or no side effects. Plants produce significant amounts of antioxidants to prevent the oxidative stress caused by photons and oxygen, therefore they represent a potential source of new compounds with antioxidant activity. FARFARE FLOS has been frequently used on the respiratory system including bronchitis, phthisis. In this study, the antioxidant activity of extract from FF was studied in vitro methods by measuring the antioxidant activity by TEAC, measuring the scavenging effects on reactive oxygen species (ROS) [superoxide anion, hydroxyl radical] and on reactive nitrogen species (RNS) [nitric oxide and peroxynitrite] as well as measuring the inhibitory effect on Cu2+-induced human LDL oxidation. The FF extracts were found to have a potent scavenging activity, as well as an inhibitory effect on LDL oxidation. And this study was designed to evaluate whether FFEA may ameliorate oxidative stress and inflammatory status through the antioxidative mechanism in LPS-stimulated RAW 264.7 murine macrophage cell line. Treatment of RAW 264.7 cells with FFEA significantly reduced LPS-stimulated inflammatory response in a dose-dependent manner. In conclusion, the FF extracts have anti-oxidative and anti-inflammatory effects in vitro system, which can be used for developing pharmaceutical drug against oxidative stress and atherosclerosis.

Potatoes were first introduced outside the Andes region four centuries ago, and have become an integral part of much of the world's food. Potatoes were first introduced into Europe in the 16th century and Korea in the early 19th century. Potatoes have a short growing season, high production per unit area, relatively strong environmental adaptability, and are cultivated in more than 130 countries around the world. It is the world's fourth-largest crop, following rice, wheat, bean and maize. In the nutritional aspects, potatoes contain abundant vitamins and minerals, as well as an assortment of phytochemicals such as carotenoids and natural phenols. Due to the high content of potato functional compounds, it has known that potatoes are effective in the prevention of various human diseases. In particular, the potato contains a large amount of polar compounds, including the saponin in the polar compounds, and the physiological activity of the saponins, such as immunity enhancement, antioxidant and anti-inflammatory is known. In this study, the antioxidative activity of polar compounds from five potatoes was examined by cell based anti-oxidation assay. The smallest amount of ROS(Reactive oxygen species) was generated when the compound was derived from 'Haryung' and 'hongyoung' and strong SOD(Superoxide dismutase) activity was observed in 'Sumi' and 'Jayoung'. The results of this study reveal the antioxidative effect of polar compounds extracted from various kind of potatoes, which will enable the acquisition of new bioactive candidates and the establishment of new profit generation models for farmers

고추에서 추출한 수용성 조다당(CAP-0)에 높은 항보체 활성이 존재함을 발견하였으며, 활성은 pronase 처리에 의해 변하지 않았으나 periodate 산화에 의해 활성이 현저히 감소하였다. CAP-0는 cetyltrimethylammonium bromide 처리에 의해 4획분(CAP-1,2,3,4)으로 분리되었으며, CAP-1에서 가장 높은 황보체 활성이 나타났다. CAP-1은 음이온 교환 chromatography에 의해 활성과 수율이 높은 CAP-1-IV와 V로 분리되었으며, III은 수율은 높았으나 활성이 매우 낮았다. CAP-1-III와 IV는 gel 여과에 의해 고분자량 획분$(M.W.\;III_a\;70,000,\;IV_a\;195,000,\;V\;140,000)$과 저분자량 획분 $III_a,\;IV_b$으로 나뉘어졌다. 이 4획분과 V는 gel 여과와 전기영동상에서 순수하였으며 고분자량 획분에서 항보체 활성이 높았다.

Objectives： Bletillae Rhizoma, the roots of Bletilla striata, is used to restrain the leakage of blood and stop bleeding. It can cure the sores, ulcers, and chapped skin. This study was designed to investigate the collagen metabolism, elastase and tyrosinase activity of Bletillae Rhizoma extract (BR). Methods : The effects of BR on type I procollagen production and collagenase activity in human normal fibroblasts Hs68 after UVB (312 nm) irradiation were measured by ELISA method. The elastase activity, tyrosinase activity, and L-DOPA oxidation after treatment of BR were measured as well. Results : In the present study, the collagen production (type I procollagen) was significantly increased to $15.7{\pm}1.8$ ng/ml at a concentration of BR 100 ${\mu}g/ml$ in UVB damaged Hs68 cells. The increased collagenase activity after UVB damage was significantly recovered to $42.7{\pm}0.7%$, $54.5{\pm}3.5%$, and $38.4{\pm}0.9%$ by BR 10, 30, and 100 ${\mu}g/ml$. The activities of BR 10 mg/ml on tyrosinase activity was significantly reduced to $45.1{\pm}8.4%$ as well. However, there were no significant effects on the elastase activity and the L-DOPA oxidation. Conclusion : BR showed the promoting effects of collagen synthesis and inhibitory effects of collagenase activity in Hs68, human normal fibroblast cells. And these could be thought to have the anti-wrinkle effects and whitening effects in vitro. These results suggest that BR may have potential as an anti-aging ingredient in cosmetic treatment.
