  • Lectin from mistletoe(Viscum coloratum) fermented by Lactobacillus plantarum was compared with the lectin from unfermented mistletoe. Agglunating activity of fermented mistletoe was stable at pH 3.77~8.71, at temperature range of $0~40^{\circ}C$ and in the presence of 9 mental ions, which results are similar to unfermented one, but less stable at pH 2.03~3.00 and more stable at temperature $60~80^{\circ}C$ than lectin from unfermented one. Agglunating activity of lectin from mistletoe fermented for 1 or 2 days and from fraction number 42~54 was not inhibited by all sugars used except for lectin from fraction number 21~34. Mitogenic activity to murine lymphpocytes of lectin from mistletoe was decreased by fermentation process.

  • In general, studies of aerial parasitic plants known collectively as mistletoe have been carried out to investigate their ecological and agricultural characteristics. However, with the recently increased level of interest in medicinal resources, research on different types of Korean mistletoe has also increased. This study was carried out to review the work on the taxonomy and ecology of Korean mistletoe in preparation for the industrial use of these plants in the future. Mistletoe types are flowering plants belonging to Santalales, which exist in the form of parasites on the branches of trees or shrubs. In Korea, five taxa of four genera in two families of mistletoe exist: Viscum coloratum (Komarov) Nakai f. coloratum, Viscum coloratum (Komarov) Nakai f. rubroaurantiacum (Makino) Kitagawa and Korthalsella japonica (Thunb.) Engl. in Santalaceae, along with Loranthus tanakae Franch. et Sav. and Taxillus yadoriki (Sieb. ex Maxim.) Danser in Loranthaceae. As taxonomic studies of these species remain insufficient and given that the distribution ranges of these species are very wide, further observations pertaining to the morphological variations in each species are necessary. The distribution of mistletoes is known to be determined by the host specificity, the interval between the hosts, the environmental condition, the habits of the host plant, the eating characteristics of mediators in the area, and their habitat selection features.

  • Korean mistletoes extracts were investigated for in vitro antioxidation activity, with 1,1-diphenyl-2-picrylhydrazine(DPPH), and an inhibitory effect on oxidative DNA damage by using comet assay. The Korean mistletoes were 4 different kinds classified by their host plants (Korean Viscum sp. in Quercus acutissima Carr., Korean Viscum sp. in Castanea crenata, Korean Viscum sp. in Betula platyphylla, and Korean Viscum sp. in Salix koreensis). The samples were extracted with ethanol, and fractonationed with n-butanol, ethyl acetate, chloroform, n-hexane, and second distilled water. Among them, ethyl acetate fraction from Korean Viscum sp. in Betula platyphylla showed the strongest activities to electron donating ability on 1,1-diphenyl-2-picrylhydrazyl(DPPH) and the protective effect on oxidative DNA damage.

  • In this study, we investigated whether Korean mistletoe (Viscum album L. var. coloratum) has anti-inflammatory effects that play key roles in the regulation of pathological mechanism of atopic dermatitis (AD). Four kinds of fractions, hexane (HX), ethyl acetate (EA), butanol (BU), and methylene chloride (MC), were used and RAW264.7 mouse macrophages and RBL-2H3 rat basophils were used to measure various inflammatory markers. EA significantly decreased mRNA expression and protein secretion levels of tumor necrosis factor alpha (TNF-α), interleukin (IL)-6, and IL-4 but HX did not affect these markers. In addition, BU decreased mRNA expressions of IL-4 and IL-6 whereas MC decreased IL-6 and TNF-α mRNA expressions. As a result, Korean mistletoe can show anti-inflammatory effects by inhibiting the secretion of cytokines related to AD, so it is thought that it will be possible to develop functional cosmetics related to this.

  • In this study, we investigated the anti-oxidant, anti-aging, and skin whitening effects of Korean mistletoe (Viscum album var. coloratum). The mistletoe fraction was composed of four types: hexane (HX), ethyl acetate (EA), butanol (BU), and methylene chloride (MC). In total phenol content assay, HX showed the highest phenol content among four fractions. In addition, EA significantly increased 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and catalase-like activities, and MC significantly increased superoxide dismutase (SOD)-like activity. When we compared IC50 value in the hyaluronidase and elastase inhibition assay, MC had the lowest IC50. In addition, we also performed tyrosinase inhibition assay to demonstrate the possibility of Korean mistletoe as a cosmetic component. HX showed the highest tyrosinase inhibition rate among the fractions.

  • The three biochemical constituents pointed out as the bioactive principles of anticancer activity of Korean mistletoes, Viscum album var. colorantum, epiphyting to different host trees, different region, and different growth environments were compared. The characterizing compounds were lectin, which was glycoprotein reported has anticancer activity, homoflavoyadorinin-B, which was flavonoid glycoside reported as an antioxidant and oleanolic acid, as an anticancerous triterpenoid. We established the analysis methods for three characterizing compounds and determined by HPLC spectrophotometer, respectively. The average content of the lectin in V. album was 1.75 mg/g of dried plants and those of homoflavoyadorinin-B and oleanolic acid were 3.51 and 5.37 mg/g, respectively. The variations of contents of the three characterizing compounds according to epiphytic trees and growth region were observed but not found statistical significance clearly. We came to the conclusion that the contents of bioactive constituents of V. album except homoflavoyadorinin-B are not affected by epiphyting trees or growth environments.

  • 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.
