  • Inner nutshell of Castanea mollisima BL (chestnut) has been used as an anti-aging and anti-wrinkle agent from the ancient time in east Asia. In order to develop new anti-aging and anti-wrinkle, ethanolic extract of inner nutshell of Castanea mollisima BL (Cor-285) was prepared and various biological activities were evaluated. Cor-285 showed potent antioxidant activity, Especially, Cor-285 possessed potent free radical scavenging activity in vitro (IC50:7.6 g/ml) compared to gallic acid (IC50:12.5 g/ml), Cor-285 showed the preventive effect against UV-induced cytotoxicity of fibroblast at concentration of 25-250 g/ml. When Cor-285 was evaluated for its anti-allergic activity, it effectively inhibited histamine release from mast cells induced by compound 48/80 (86% inhibition at 10 mg/ml). The inhibitory activity was stronger than that of glycyrrhiznate. Cor-285 also showed in vivo inhibition against delayed hypersensitivity as well as croton-oil induced ear edema in mice when topically applied These results strongly suggest that Cor-285 may reduce immunoregulatory 1 inflammatory skin trouble. From the attempts to isolate the constituents, citropten (simple coumarin) and ellagic acid, a well known radical scavenger, were isolated. In a clinical trial of twenty healthy volunteers with aged skin,6 weeks application of Cor-285 (3% cream) decreased wrinkle about 26% and increased moisturizing 20% on the skin. All of these results indicate that Cor-285 may be an effective anti-aging and anti-wrinkle agent.

  • The methanolic extract of Rosa davurica Pall. roots exhibited strong antioxidant activity in a 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging assay and was found to be a dose-dependent inhibitor of non-enzymatic formation of advanced glycation end products (AGEs), which are relevant to diabetes complications. HPLC-diode array detector (DAD) analysis of the R. davurica Pall. root extract led to the identification of four compounds: hydrocaffeic acid, catechin, epicatechin, and ellagic acid. Catechin was present in the largest amount and exhibited high antiglycation activity. A CYP3A4 assay was used to investigate potential interactions between drugs and the extract, and results suggest that the R. davurica Pall. root extract had moderate potential for interfering with drug metabolism. The R. davurica Pall. extract did not display anti-inflammatory activity on the level of that for tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in a lipopolysaccharide (LPS)-stimulated macrophage assay; however, the extract did exhibit low to moderate immunostimulatory activity in a pro-inflammatory macrophage assay. Therefore, we conclude that R. davurica Pall. root is a promising anti-AGE agent with low to moderate risks of associated inflammation or drug interaction.

  • Uric acid is the end product of purine metabolism in human body, originating from hypoxanthine after enzyme catalysis by Xanthine oxidase (XOD). Hyperuricemia results as a result of either over-generation of uric acid or a reduction in its excretion. In silico modelling methods such as Absorption, Distribution, Metabolism, Excretion and Toxicity (ADMET) prediction, Autodock 4.2.6 program were used to study the potential inhibitory compounds of XOD. Also we investigated the inhibition of XOD activity by using the extracts of Dendropanax morbifera and Rubus coreanus Miq spectrophotometrically. According to ADMET data, several compounds from D. morbifera and R. coreanus plants, were found to be more potent in inhibiting the XOD activity than allopurinol. XOD inhibitory activity is evaluated by quantifying the formation of uric acid by measuring the absorbance at 290 m ($A_{290}$).D. morbifera extract inhibited XOD activity at $250{\mu}g/ml$, however the extracts from R. coreanus has inhibited XOD activity at $25{\mu}g/ml$. The major compound of R. coreanus, ellagic acid significantly increased the inhibition rate from $9{\mu}g/ml$ and showed a 71% suppression rate at $15{\mu}g/ml$. Finally, these results suggested a potential inhibitory activities of the extracts from D. morbifera and R. coreanus Miq, but further research is needed to validate to ensure their safe usage as drug.

  • In this study, we investigated the influences of abnormal high temperature on growth, yield and physiologically active substances of the strawberry. General strawberry cultivars in the $20^{\circ}C$ growth condition showed much better growth of leaf number, length, diameter along with plant height, compared with those in $22.5^{\circ}C$ or $25^{\circ}C$. But the cultivars of both 'Sulhyang' and 'Mehyang' showed good growth and development at $25^{\circ}C$ with the roots showing great growth at $20^{\circ}C$. The quality and yield of the strawberry were best in the $20^{\circ}C$ growth condition, but the merchantability deteriorated in the $25^{\circ}C$ high temperature condition. As for the content of the physiologically active substances of the strawberry, it increased at $20^{\circ}C$, the optimum growth temperature, but decreased at $25^{\circ}C$. The physiologically active substances in the strawberry differed among the cultivars, the contents of cyanidin-3-glucoside, cinchonine, ellagic acid and cinnamic acid higher in the 'Mehyang', whereas the content of fisetin is higher in the 'Sulhyang' cultivar.Consequentially, the high temperature in summer has a negative effect on the physiological active ingredients of the strawberry, which was increased in the strawberry cultivated at proper temperature, and high quality strawberry production was possible.

  • Cancer is an abnormal growth of cells in body which leads to death. These cells are born due to imbalance in cell proliferation mechanism. In 2018, WHO released new statistics on cancer incidence, mortality, and prevalence worldwide i.e., GLOBOCAN 2018 estimates for 28 types of cancer in which more prevalence of cervix and breast cancer. According to survey, in India about 7.8 million cancer deaths and 11.5 million new cases arise in 2018, which will increase to 19.3 million new cases per year by 2025. Though breast cancer as such is not explained anywhere in Ayurvedic compendia, correlations can be done with the Stana Arbuda. Ayurveda, the ancient system of medicine came into existence 1000's of years ago with an objective of maintaining the health of people and treating diseases. Many herbs used in Ayurveda have been screened for activity against cancer and in-vitro and in-vivo studies have given promising leads. The plant, called as "Mother of Medicine", Haritaki has been extensively studied for its various ailments because of its extraordinary healing potency. Haritaki (Terminalia chebula Retz.), Family: Combretaceae have a great therapeutic value and is widely distributed in India. Dried fruit of Terminalia chebula contains high quantities phenolic compounds consist of ellagic acid, gallic acid and chebulic acid. The fruit extract of T. chebula is having different biological properties like anticancer, antioxidant, hepatic and renal protective activities etc. In this study, we focus on the use of CO2 extract of Terminalia chebula, on the breast cancer cell line MDA-MB-231. All tests proved that CO2 extract of Terminalia chebula containing active chemical component, therefore our experiment showed the positive results for CO2 extract of Terminalia chebula against breast cancer cell line cancer MDA-MB-231. The MTT assay results were used to evaluate the anti-cancer activity of the extract. The percentage of cell growth and cell viability were calculated from tabulated result values of MTT assay. Cell viability MTT assay also showed significant growth inhibition, at the same time statistical analysis of MTT assay also proved significant results.

  • A 60-d feeding trial was conducted to evaluate the effects of diets supplemented with two concentrations (0% and 0.3%) of black raspberry (Rubus coreanus Miquel) fruit by-product (RCFB) on the physicochemical characteristics, oxidative stability, antioxidant capacity, antioxidant enzyme activity, and fatty acid profile of M. longissimus dorsi (LL) porcine muscle from Berkshire finishing pigs meat. Results revealed that regardless of the sex, diets supplemented with 0.3% RCFB reduced (p<0.05) the thiobarbituric acid reactive substances (TBARS) expressed as malonaldehyde (MDA) content effectively. A higher antioxidant capacity [2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity] was found (p<0.05) in response to feeding supplemented with 0.3% RCBF for male or female pigs. Moreover, 0.3% RCFB dietary feed increased (p<0.05) the glutathione peroxidase enzyme activities (GPX1) in blood plasma for male or female pigs. However, no influences were observed (p>0.05) on meat color, WHC, shear force, and fatty acid contents while fed diet supplemented with 0% or 0.3% RCFB for male or female pigs. Overall, this study suggests that a diet supplemented with 0.3% RCFB may beneficially affect owing to better oxidative stability, higher antioxidant capacity, and antioxidant enzyme activity (blood plasma) in pigs which could be a promising natural antioxidant without affecting meat quality traits.

  • 본 연구에서는 DNCB 도포를 통해 아토피 피부염을 유발시킨 NC/Nga mice에 율피 발효물을 각각 0.1%, 1%, 5%로 도포하고 항아토피 효능을 평가하였다. 율피 발효물의 유효성분은 HPLC 분석 결과, gallic acid와 ellagic acid가 각각 10.18 mg/g, 2.14 mg/g 함량을 나타내었다. 실험군 간의 유의적 체중 변화는 관찰되지 않았으며, 육안 평가를 통해 홍반, 가려움과 피부건조, 부종과 혈종, 짓무름 그리고 태선화와 같은 일반적인 아토피 피부염 증상의 심각도를 측정한 점수 결과에서는 DNCB 도포를 통해 아토피 피부염을 유발한 atopic dermatitis(AD)군($13.17{\pm}0.40$)과 비교 시, 아토피 피부염 유발 후 5% 율피 발효물을 도포한 fermented Castanea crenata inner shell(FCS) 5군에서 $7.50{\pm}0.43$ 으로 나타나 아토피 피부염 증상이 빠르게 개선되는 것을 확인하였다(P<0.01). 피부 측정 기기인 MPA5 580을 이용하여 피부멜라닌지수, 피부홍반지수, 피부수분지수를 측정한 결과, AD군은 각각 $296.61{\pm}8.11$, $264.33{\pm}10.15$, $3.15{\pm}0.54$를 나타내었으며 FCS 5군은 각각 $105.86{\pm}2.92$, $199.56{\pm}4.22$, $17.62{\pm}1.75$로 개선효과가 유의적으로 나타났다(P<0.05). 각 실험군 mice의 면역반응을 확인하기 위해 비장 무게(mg)를 체중(g)으로 나누어 산출한 비장 수치의 경우, 아토피 피부염 유발로 인해 AD군에서 증가된 비장 수치($5.55{\pm}0.31$)가 FCS 0.1군, FCS 1군, FCS 5군에서는 각각 $4.53{\pm}0.24$, $3.80{\pm}0.40$, $3.32{\pm}0.24$로 나타나 율피 발효물의 도포 농도에 의존적으로 감소되는 경향을 나타냈으며 특히 FCS 5군에서는 유의적으로 낮게 나타났다(P<0.05). 이는 율피 발효물이 아토피 피부염 상태에서 증가된 비장 내 T-림프구를 효과적으로 억제할 수 있음을 나타낸다. Quantitative real-time PCR을 통해 피부조직에서 IL-$1{\beta}$, TNF-${\alpha}$와 같은 염증 유전자의 발현 변화를 분석한 결과, 두 유전자 모두 정상군의 relative quantification값이 1일 때 AD군은 각각 1.30, 1.26으로 증가되었으며 FCS 5군에서는 1.11, 0.93으로 나타나 율피 발효물 도포에 의한 유의적인 감소(P<0.05)를 확인할 수 있었다. 아토피 피부염의 면역학적 지표인 혈청 내 IgE 함량을 분석한 결과에서는 각 실험군 간의 유의적 차이는 보이지 않았으나 AD군($1,628.71{\pm}202.59ng/mL$)과 비교 시, 율피 발효물을 도포한 FCS 0.1군, FCS 1군, FCS 5군에서 각각 $1,530.15{\pm}198.70ng/mL$, $1,462.15{\pm}83.79ng/mL$, $1,187.47{\pm}140.09ng/mL$로 나타나 율피 발효물 도포에 의해 감소되는 경향을 확인할 수 있었다. 따라서 율피 발효물은 아토피 피부염 증상 개선을 위한 기능성 천연물의 소재로 활용될 수 있을 것이라 생각된다.

  • 지리산에서 자생하는 5종(참나물, 꿩의비름, 함박꽃나무, 산오이풀, 배초향)의 식물을 선정하여 5월부터 9월까지 자생지에서 꽃이 활짝 개화한 상태에서 채집하였다. 채집한 식물은 전초는 추출하여 17종의 폴리페놀 성분을 분석하고 다음으로 꽃, 잎, 줄기, 뿌리를 분리하여 각 부위의 추출물로 DPPH, ABTS, 폴리페놀, 플라보노이드에 관한 실험을 진행하였던바 결과는 다음과 같다. 1. 지리산에 자생하는 5종의 식물에 함유된 폴리페놀 성분은 총 13가지였으며 그중 가장 많은 검출된 물질의 총 함량은 산오이풀로 126.2ppm이었으며 주 물질은 ellagic acid(=ELA) 122.4ppm이었다. 2. DPPH radical 소거활성을 살펴본 결과 산오이풀의 꽃, 줄기, 뿌리에서 가장 좋았으며 다른 식물에서는 꽃 추출물에서 좋은 소거활성도를 나타냈다. 3. ABTS radical 소거활성도가 가장 높은 것은 산오이풀 꽃 추출물에서 가장 높은 13.5㎍/㎖에서였고, 뿌리 16.8㎍/㎖, 잎 22.6㎍/㎖ 순이었다. 그 외 다른 식물에서는 그렇게 큰 ABTS radical 소거활성능을 확인할 수 없었지만 전체적으로 꽃 추출물이 다른 부위인 잎과 뿌리 추출물보다 좋았다. 4. 총 폴리페놀 함량은 가장 많은 것은 함박꽃나무는 잎에서는 161.4mg GAE/g으로 가장 많았고, 다음으로 함박꽃나무의 뿌리와 배초향 뿌리에서 가장 많은 130.0mg GAE/g이었다. 또한 가장 낮은 것은 산오이풀로 나타났다. 5. 총 플라보노이드 함량은 배초향의 뿌리로 186.2mg CAE/g, 꽃에서 166.9mg CAE/g, 잎에서 가장 낮은 116.1mg CAE/g이었다. 이상의 결과에서 나타나듯 산오이풀은 항산화 효능도 우수하며 폴리페놀 성분의 함량도 많아 앞으로 화장품 산업에 충분히 이용 가능할 것이라 생각된다.
