  • 본 연구에서는 한국산 겨우살이 (Viscum album L. var. coloratum)이 아토피 피부염과 관련된 염증성 사이토카인에 영향을 미치는지 여부를 알아보았다. 실험에는 헥산, 부탄올, 에틸아세테이트, 메틸렌클로라이드, 총 4 가지 분획물을 사용하였으며, RAW264.7 마우스 대식세포와 RBL-2H3 렛트 호중구를 이용하여 염증성 마커를 연구하였다. 실험 결과 에틸아세테이트 분획이 tumor necrosis factor alpha (TNF-α), interleukin(IL)-6, IL-4의 mRNA 발현 및 단백질 분비량을 감소시켰으나, 헥산 분획은 뚜렷한 효능이 없었다. 또한 부탄올 분획은 IL-4, IL-6의 mRNA 발현을 감소시켰고, 메틸렌클로라이드 분획은 IL-4와 TNF-α의 mRNA 발현을 감소시켰다. 결과적으로 한국산 겨우살이(V. album var. coloratum)가 아토피 피부염과 관련된 사이토카인 분비를 억제시켜 항염증 효과를 나타낼 수 있으므로, 이와 관련된 기능성 화장품 개발이 가능할 것으로 사료된다.

  • "향약채취월령"과 "동의보감"을 비롯한 우리나라 옛 문헌에 나오는 식물명 상기생(桑寄生)은 지금까지 뽕나무겨우살이(Loranthus parasiticus), 꼬리겨우살이(Loranthus tanakae), 참나무겨우살이(Taxillus yadoriki), 뽕나무겨우살이(Taxillus chinensis), 동백나무겨우살이(Korthalsella japonica), 그리고 겨우살이(Viscum album var. coloratum)로 알려져 왔다. 최근에는 상기생(桑寄生)이 국내에는 분포하지 않는다는 주장도 제기되었으나, 옛 문헌에 기록된 상기생은 중국에서 부르는 상기생, 즉 Taxillus sutchuenensis과는 다른 겨우살이(V. album var. coloratum)임이 확인되었다. 상기생을 뽕나무겨우살이라고 불렀으나, 최근에는 겨우살이로 부르고 있음이 확인되었다.

  • 본 연구에서는 한국산 겨우살이(Viscum album var. coloratum)의 항산화, 항노화, 미백 효능을 알아보았다. 겨우살이 분획물은 hexane (HX), ethyl acetate (EA), butanol (BU), methylene chloride (MC) 총 4 가지를 사용하였다. 실험 결과 HX 분획물이 4 가지 분획물 중 가장 높은 페놀 함량을 보였다. 또한 EA 분획물이 가장 높은 1,1-diphenyl-2-picrylhydrazyl (DPPH)자유 라디칼 소거능 및 catalase-유사 활성을 나타내었으며, MC 분획물이 가장 높은 superoxide dismutase (SOD)-유사 활성을 나타냈다. MC 분획물은 또한 가장 우수한 hyaluronidase와 elastase 억제능을 보였다. 미백 효능을 알아보기 위하여 tyrosinase 억제능을 알아보았는데, HX 분획물이 가장 우수한 억제능을 보여주었다. 본 연구 결과를 통하여 한국산 겨우살이는 항산화, 항노화 및 미백 활성을 가지는 기능성 화장품 소재로 사용이 가능할 것으로 보인다.

  • This study was conducted to assess the quality characteristics and antioxidant activity of yanggaeng prepared with different concentrations of Viscum album extracts (VAE; 0, 1, 3 and 5%). The moisture content ranged from 37.85% to 39.38%, exhibiting no significant differences between the groups. The pH level of VAE 5% added yanggaeng was the lowest, followed in order by 3% and 1% additions. Increasing the amount of VAE in yanggaeng tended to increase acidity. The lightness value of the Hunter color system decreased based on the amount of VAE concentrate added to yanggaeng. As VAE content increased, changes in hardness, gumminess, and brittleness were all significant (p<0.05). Characteristics of cohesiveness and springiness showed no significant differences. Total polyphenol content was the highest in VAE 5% added yanggaeng. Antioxidant activities such as DPPH radical scavenging activity of the control group was 2.29%, whereas groups with added VAE ranged from 7.52~28.05%. As VAE increased, antioxidative activity also increased. In the sensory evaluation, yanggaeng addition with VAE 3% had excellent scores for bitterness, moistness, and overall acceptability. Yanggaengs with moderate levels of VAE 3% are recommended (with respect to overall preference score) to take advantage of the functional properties of VAE without sacrificing consumer acceptability.

  • Berries of Korean mistletoe (Viscum album var. coloratum [Kom.] Ohwi) contained one seed, which have, in general, one or two embryos but very rarely three embryos. Mucilaginous substances in berries may help them adhere to the branches of host trees. It was observed that seeds need more than one and half years to develop into normal and healthy seedlings from the time of inoculation. Many factors such as adhesion of berry, thickness of host branch, orientation of haustorial root, etc. influenced the successful development of mistletoe plants. Through the application of six-year observation results on the germination of seeds and growth of seedlings, about 80% of germination rate for mistletoe seeds and 61% of survival ratio for germinated seeds, which is more than 23 times higher in natural conditions, were obtained after inoculation of seeds on the one-year-old branches of Malus pumila var. dulcissima and Quercus mongolica trees. The technological aspects of the success can be applied to other host plants and provide a critical clue to an artificial propagation system, for this medicinally valuable genus. This is the first successful report on artificial inoculation and plant development of Korean mistletoe.

  • Viscum album var. coloratum (mistletoe) is considered as one of the endangered plant species in Korea. Our objective is to restore its population and multiplication of plant by ex situ method. In this research we explored the maximum germination (in vitro) of freshly harvested and stored seeds of mistletoe collected in different time intervals. Ex vitro germination after artificial inoculation on the branches of Prunus mume in different physiological conditions was also monitored. The research revealed that the lately harvested seeds (Feb. and March 2014) were superior over early harvested seeds (Nov. 2013 and Jan. 2014) of mistletoe due to the higher percentage of germination (above 93%). According to the data, it is also revealed that the survival and germination rate of mistletoe seeds decreased with the increase in storage duration. In ex vitro germination, the fluctuated temperature of a glass house in natural condition enhanced (four fold) the rate of germination on the branches of Prunus mume than the constant temperature condition in the glass house.

  • Lectins and its A- and B-chains from Korean mistletoe (Viscum album var. coloratum) were isolated by affinity chromatography on the Sepharose 4B modified by lactose-BSA conjugate synthesized by reductive amination of ligand (lactose) to .epsilon.-amino groups of lysine residues of spacer (BSA) after reduction by $NaCNBH_3$. The lactose-BSA conjugate was coupled to Sepharose 4B activated by cyanogen bromide. The molecular weight determined by SDS-PAGE were a 31 kD of A-chain and a 35kD of B-chain. Amino acid analysis and N-terminal sequencing were performed. The effects of pH, temperature and guanidine chloride on the conformation of the lectin were investigated by measuring its intrinsic fluorescence and compared with its hemagglutinating activities. Blue shift was detected on the acidic pH and there was a close relationship between activities and conformation of the lectin. Under denaturing conditions, the tryptophan emission profile of lectin showed typical denaturaiional red shift which also correspond to the conformations and activity of lectin.

  • The aqueous extract of European mistletoe (Viscum album, L.) has been used in cancer therapy. The purified mistletoe lectins, main components of mistletoe, have demonstrated cytotoxic and immune-system-stimulating activities. Korean mistletoe (Viscum album L. coloratum), a subspecies of European mistletoe, has also been reported to possess anticancer and immunological activities. A galactose- and N-acetyl-D-galactosamine-specific lectin (Viscum album L. coloratum agglutinin, VCA) with Mr 60 kDa was isolated from Korean mistletoe. Mistletoe preparations have been given subcutaneously due to the low stability of lectin in the gastrointestinal (GI) tract. In the present study, we investigated the possibility of alginate/chitosan microcapsules as a tool for oral delivery of mistletoe lectin. In addition, our strategy has been to develop a system composed of stabilizing cores (granules), which contain mistletoe lectin, extract or powder, coated by a biodegradable polymer wall. Our results indicated that successful incorporation of VCA into alginate/chitosan microcapsules has been achieved and that the alginate/chitosan microcapsule protected the VCA from degradation at acidic pH values. And coating the VCA with polyacrylic polymers, Eudragit, produced outstanding results with ideal release profiles and only minimal losses of cytotoxicity after manufacturing step. The granules prepared with extract or whole plant produced the best results due to the stability in the extract or whole plant during manufacturing process.
