  • The objective of this study was to clarify the distribution, host preference and habitat characterstics of the endangered mistletoe species, Loranthus tanakae in Korea. Seven sites were selected for sampling in Gangwon Province, located in middle of Korea. Parameters including DBH, attached height, twig death, and the number of L. tanakae and Viscum album var. coloratum per tree for all infected individuals were investigated. One thousand, two hundred and seventy L. tanakae plants were found on the 420 host trees with 665 V. album var. coloratum on 227 of the trees. The infested host trees belonged to eight species and one variety species from six genera and five families. The highest percentage (86.9%) of individuals of L. tanakae were growing on Fagaceae. The infected trees occurred between altitudes of 420 m and 1,250 m above the sea level, but most of them were between 600 m and 900 m. The mean DBH and heights of parasitism were 38.6 cm and 13.0 m, respectively. Twig death was also observed on 300 host trees (71.4%) and 1.5 twig per tree. Most of the populations and the distribution of L. tanakae were highly affected by DBH out of some individual tree characteristics.

  • The objective of this study was to evaluate the effects of different levels of red ginseng mare or Korean mistletoe powder on growth performance and physicochemical properties of thigh meat in broiler. A total of 200 broiler chicks were divided into five groups were fed a basal diet (control), basal diet supplemented with 0.5% red ginseng mare (T1), red ginseng mare 1% added (T2), Korean mistletoe 0.5% added (T3), Korean mistletoe 0.5% added (T4) for five weeks. Growth performance and proximate composition of chicken thigh meat were not influenced by all treatments, except for mortality and crude fat, which was significantly lower in all treatments with red ginseng mare or Korean mistletoe powder compared to control. Dietary red ginseng mare and Korean mistletoe supplementation had no significantly effects on pH, WHC, shear force, CIE $L^*$, $b^*$ values, triglyceride and glucose but TBARS values total cholesterol, and LDL-cholesterol were decreased (P<0.05) by the addition red ginseng mare and Korean mistletoe powder. CIE $a^*$ values increased significantly with added red ginseng mare and Korean mistletoe powder relative to the control (P<0.05). It was concluded that the addition of red ginseng mare and Korean mistletoe powder revealed minor improvements in the lipid oxidative stability of chicken meat.

A review of the taxonomic and ecological characteristics of Korean mistletoe types (Viscum, Korthalsella, Loranthus and Taxillus) (한국산 겨우살이류(Viscum, Korthalsella, Loranthus and Taxillus)의 분류 및 생태학적 특성 고찰)

  • 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.

  • References in the modern Korean literature in this area to the Korean medicinal plant name written in Chinese script and expressed as Sanggisaeng have been extremely confusing. This name has been considered as six species, specifically Loranthus parasiticus, Loranthus tanakae, Taxillus yadoriki, Taxillus chinensis, Korthalsella japonica, and Viscum album var. coloratum. Recently, it was suggested that sanggisaeng is not distributed in Korea; however, the plant name Sanggisaeng recorded in old Korean literature sources, such as in the Hyang-yak-chae-chwi-wol-lyeong, Hyang-yak-jib-seong-bang, and Dong-ui-bo-gam sources, among others, was identified using the name V. album var. coloratum, whereas in China, Sanggisaeng was referred to as T. sutchuenensis. The Hangeul name of Sanggisaeng had been Ppongnamugyeousali, but now the name Gyeousali is widely used.

  • Antioxidant, α-glucosidase inhibition, and anticoagulant effects of 80% ethanolic extract from mistletoe (Viscum album var. coloratum) were investigated. The yield and polyphenol content of the mistletoe extract were 30.9±0.4% and 57.6±1.5 mg gallic acid equivalents/g, respectively. The antioxidant effects of the mistletoe extract such as free and cationic radical scavenging ability, nitrite scavenging ability, and reducing power increased in proportion to its concentration. Also the mistletoe extract inhibited the activity of α-glucosidase, and delayed plasma coagulation mainly by inhibiting the extrinsic and common pathways in blood coagulation system.

  • The biological activities on human immune and cancer cell lines of the four kinds of Korean mistletoes (Korean Viscum album, var. coloratum, : 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) extracts were investigated. The extracts were preparated with ethanol, and fractionated with n-butanol, ethyl acetate, chloroform, hexane, and second distilled water. Cytotoxic potencies of the fractions on human normal lung cell line (HEL 299) showed under 28% in the concentration of 0.5 mg/ml. Growth inhibition effect of the Korean mistletoe extracts on the several human cancer cell lines depends on the concentration of the extracts, and extracting solvent. The hexane, chloroform, and ethyl acetate fractions indicated a strong anticancer activity, but not in aqueous and butanol fractions. Some mistletoe fractions have a different characteristic on the cancer cell lines. Stimulation on the growth of human immuno cell lines(B cell : Raji, T cell: Jurkat) of the extracts were confirmed in the ethyl acetate, chloroform, hexane fractions, but not in aqueous system.

  • Recently, the consumption of mistletoe[Viscum album var. coloratum(Kom.) Ohwi] is increasing because of its good medical effectiveness with the increased concern on the natural medicines and foods. The result obtained from the investigation on the stem tissues of the mistletoe and the oriental chestnut oak, a host plant species, are as follows. Haustorium from the seeds of the mistletoe after their sticking to the branches of the host plant penetrates into the bark where it forms the endophyte system through the active cell division. The endophyte grown in the cambium of the host plant makes the stems and leaves as the outer tissues in a certain time. Even through lignification of the host wood in the branches the oriental chestnut oak was not progressive, its tylosis coas developed partially assembly due to the formation of the endophyte. The stems of the mistletoe consisted of vascular tracheid, selereid, and ray and axial parenchyma, classified as a hardwood without vessels. The vascular tracheids seemed to take a role instead of the vessels in the mistletoe plant from the result that the pits of the vessels in the host branches are linked to the vessel-form tracheid in the mistletoe stems. The constituent ratio of the sclereid cells in the mistletoe stems increased with aging. Furthermore their ratio of the parenchyma cells was higher, which contained the more cell content, compared with the cells of the general woody plant species.

  • 매실나무겨우살이 막걸리의 생리적 효능을 검정하여 의약 화장품의 소재화 가능성을 검토할 목적으로 발효기간과 겨우살이 함량에 따른 총 폴리페놀, 플라보노이드 함량, DPPH free radical 소거능을 측정하였고, tyrosinase 저해활성은 5분 간격으로 65분간 측정하였다. 막걸리는 백미와 기장을 7:3의 비율로, 겨우살이의 함량을 0%, 5%, 10%로 달리하여 10일 간격으로 최대 30일까지 Shaking incubator($30{\sim}35^{\circ}C$, 100 rpm)에서 발효하였고, 발효가 끝난 막걸리는 80 mesh 망으로 여과하였다. 총 폴리페놀 함량은 10일에 최대치를 나타내었고, 0%는 $633.53{\mu}g/ml$, 5%는 $759.67{\mu}g/ml$, 10%는 $752.2{\mu}g/ml$을 나타내었다. 기간이 경과함에 따라 감소하는 경향이었으며 30일에 0%는 $507.57{\mu}g/ml$, 5%는 $570.13{\mu}g/ml$, 10%는 $551{\mu}g/ml$를 함유하고 있는 것으로 나타났다. 총 플라보노이드 함량 또한 10일에 최대치를 나타내었고, 0%는 $16.18{\mu}g/ml$, 5%는 $63.87{\mu}g/ml$, 10%는 $62.99{\mu}g/ml$였고, 기간이 경과함에 따라 감소하는 경향성을 나타내어 30일에 0%는 $0.59{\mu}g/ml$, 5%는 $10.98{\mu}g/ml$, 10%는 $1.18{\mu}g/ml$를 함유하였다. DPPH free radical 소거능은 0%의 경우 10일에 72.34%로 최대치가 나타났고, 30일에 58.61%로 가장 낮은 소거능을 보여주어 기간이 경과함에 따라 감소하는 경향성을 보여주었다. 하지만, 겨우살이 첨가군인 5%(10일:91.13%, 20일:91.09%)와 10%(10일:91%, 20일:90.8%)는 비교적 차이가 없었고, 발효기간이 30일이 경과한 후 5%는 93.46%, 10%는 92.3%로 최대값을 보여주었다. Tyrosinase 저해활성은 DPPH free radical 소거능이 가장 좋은 30일 발효 막걸리를 측정하였다. 모든 겨우살이 첨가군에서 5분이 경과하였을 때, 0%는 82.68%, 5%는 69.29%, 10%는 79.53%의 저해활성을 나타내었으며, 시간에 유의적으로 저해활성이 감소하였다. 본 연구 결과에 따르면, 겨우살이 막걸리의 총 폴리페놀과 플라보노이드 함량은 기간이 경과함에 따라 감소함에도 불구하고, DPPH free radical 소거능은 증가함을 알 수 있었다. Tyrosinase 저해활성은 5% 첨가 막걸리에서 가장 낮았으며, 겨우살이를 첨가하지 않은 0%에서 가장 저해활성이 높고 오랜시간 유지되는 것을 확인할 수 있었다.

  • Effects of growth regulators and culture conditions on seed germination, haustorium development, and callus formation of Korean mistletoe (Viscum album var. coloratum (Kom.) Ohwi) were described. Histological examination showed that seed of V. album contained one or two zygotic embryos with rod shape, and actively dividing cells were mainly distributed in radicle region rather than cotyledon of zygotic embryo. The most significant factor for seed germination and haustorium development of V. album was the requirement of the light. Various growth regulators examined in this study failed to substitute the effect of the light on seed germination. The frequency of callus formation was highest at 27.3% when flower buds were cultured onto B5 medium containing $0.1\;mgl^{-1}$ IAA. Explants from other organs were recalcitrant in forming calluses. Culture conditions described in this study could be applied for production of useful metabolites and multiplication of V. album in future.
