The study examined qualities including chlorophyll, total phenol, total flavonoid content and antioxidative activity in 7-year-old mistletoe that was artificially cultivated with Japanese apricots as the host. The chlorophyll a content of the artificially cultivated Japanese apricot mistletoe leaves was 7.67 mg/g (old leaves) and 3.17 mg/g (new leaves), while the chlorophyll b content was 0.80 ~ 3.53 mg/g and 1.31 ~ 3.56 mg/g. The carotenoid content of the Japanese apricot mistletoe leaves were in the range of 0.29 ~ 2.48 mg/g, and the old leaves (1.85 mg/g) had a carotenoid content 2.1 times higher than the new leaves (0.89 mg/g). The total polyphenol content of the leaves and nodes of the 7-year-old mistletoe was 60.22 mg/100 g TAE for the leaves and 35.50 mg/100 g TAE for the nodes. Among the host trees, polyphenol content was highest (81.44 mg/100 g TAE) in the old mistletoe leaves of the Quercus mongolica, while the total flavonoid content of the Japanese apricot mistletoe was higher in the new leaves (47.89 mg/100 g RUE) than the old leaves (42.19 mg/100 g RUE). The DPPH radical scavenging ability of the Japanese apricot mistletoe scored a low 22.4 ~ 28.5% in the leaves, but was relatively high in the nodes at 52.4 ~ 80.1%. In terms of 1mg/mL concentration, the new leaves (69.1%) and old leaves (82.3%) of the Quercus monglica mistletoe displayed the highest inhibition rate. Chestnut mistletoe displayed an inhibition rate of 21.9 ~ 31.9% for the leaves, and 35.0 ~ 63.8% for the nodes. These results indicate that Japanese apricot mistletoe would be substitute oak tree mistletoe as a source of bio-active property for functional food and medicine.

This study was conducted to investigate the total polyphenol, total flavonoid and the antioxidant activity in different origin and parts of Moringa olerifera cultivated in Cheorwon. The extraction yield from leaf, root and stem were 25.5, 23.0, 12.3%, respectively. The total polyphenol content was high in the leaf extracts (15.77 mg/g) followed by root extracts (11.23 mg/g) and stem extracts (3.50 mg/g) but the difference of origin was not observed. The total flavonoid content was high in the leaf extracts (14.78 mg/g) followed by stem (1.36 mg/g) and root (1.14 mg/g). The total flavonoid content of Philippines and Thailand leaf were statistically high compared to india leaf. The DPPH radical scavenging activity was high in the leaf extracts at the 1 mg/ml, 0.25 mg/ml but the difference of origin was not observed. The DPPH radical scavenging activity may be attributed to the presence of several compounds such as polyphenol and flavonoid. Hence consumption of diet supplemented with Moringa olerifera leaves could protect the human against diseases induced by oxidative stress.

Background : Mistletoe grown in eurasian continent range from England to northern Asia. It has abundant chlorophyll and phenolic compound in node and leaf which has anticancer activity. The purpose of the study is to improve nutritional quality and composition of the amino acids and mineral along with increasing seed set rates and productivity of Viscum album on Prunus mume. Methods and Results : This study was conducted to compare plant nutrients such as total nitrogen, Ca, Fe, K, Mg, Mn, Na, P and composition of amimo acids in leaves between Viscum album and its host tree, Prunus mume, which were artificially cultivated in field and green house with or without treatment of fertilizer. Total nirogen content in leaves of mistletoe and its host tree, Prunus mume was 3.90% and 2.09% in the fields fertilized and non-fertilized, respectively. In a greenhouse fertilized, mistletoe leaves contained higher nitrogen (3.78%) compared to the host tree (3.06%). NO3-N content in leaves was also higher in mistletoe (37.5 ppm & 20 ppm) than in host tree (22.5 ppm & 12 ppm) in a field fertilized and non-fertilized. Ca content (1.18%) were same in leaves of mistletoe and host tree in the field fertilized. Contents of Fe, K, and Mn in leaves of mistletoe were 61.37 ㎎/㎏, 3.33%, and 127.59 ㎎/㎏, which were 16%, 13%, and 48% lower than host tree, respectively. On the other hand, contents of Mg, N, and P were 0.22%, 127.95 ㎎/㎏, and 0.48%, which were 5%, 148%, and 92% higher than host tree, respectively. K contents were higher in host tree fertilized (3.33% in field & 2.55% in greenhouse) while higher K (4.07%) was contained in a field non-fertilized compare to host tree (3.96%). However, P content was higher in mistletoe grown in field (0.48%) and greenhouse (0.42%) fertilized. In non-fertilized field, mistletoe leaves contained higher P (0.65%) rather than in host tree (0.29%). Eighteen kinds of amino acids were investigated in leaves of host plant by 20 - 87%. Conclusion : This study indicates that nutrient management including fertilization is important to improve nutritional quality and productivity of mistletoe in the artificial cultivation on Prunus mume.

수요증가가 예상되는 겨우살이의 인공번식을 위한 기초자료로 활용하고자 겨우살이의 분포지역의 기주수종과 서식지 환경을 조사하여 분석하였다. 겨우살이의 자생지는 전국에 분포하고 있었으며, 기주식물로는 졸참나무와 같은 참나무류가 대부분이였고 밤나무, 벚나무, 오리나무, 돌배나무 등에서 볼 수 있었다. 군락지의 같이 자생하는 침엽수인 소나무, 잣나무와 활엽수인 느티나무, 감나무, 고로쇠나무, 단풍나무, 뽕나무, 은행나무에서는 관찰되지 않았다. 자생지의 고도는 해발 0~1200 m까지 잘 생육되고 방향과 지형을 가리지 않고 기주식물이 잘 생육 할 수 있는 곳이면 전국에서 재배가 가능할 것으로 판단되었으며, 종자 전파는 조류에 의함이 확인할 수 있었다. 겨우살이의 기생은 흡기 발생부터 기주식물의 표피 또는 조직성분에 따라 영향이 있을 것으로 생각되며 인공재배 연구의 좋은 성과를 위해 겨우살이가 잘 기생하는 기주식물의 기주 특이성에 대한 연구가 이루어져야 할 것으로 사료된다.

최근 천연의 의약품과 식품에 대한 관심이 높아지면서 약리성분이 우수하여 수요가 증가하고 있는 겨우살이 [Viscum album var. coloratum(Kom.) Ohwi] 와 겨우살이의 기주식물인 상수리나무(Quercus acutissima Carr.)가지의 조직특성을 조사하고 인공재배 기초 자료로 활용하기 위하여 수행한 결과는 다음과 같다. 겨우살이 종자가 기주목에 부착되면 종자로부터 성장한 흡기가 수피를 뚫고 들어가 형성층 부위에서 왕성한 세포분열을 통하여 여러 갈래로 분지를 형성하며, endophyte가 수피 속에서 성장하다가 일정한 시기가 되면 수피 외부조직으로 발달하여 줄기와 잎으로 성장하였다. 겨우살이 기주목인 상수리나무의 가지는 심재화가 진행되지 않았지만 타일로시스가 부분적으로 발달한 것은 겨우살이 endophyte의 침투영향으로 생각된다. 겨우살이 줄기의 구성세포는 도관상 가도관, 후벽세포, 방사유세포, 축방향유세포로 구성되어 있으며 활엽수로 분류되지만 도관이 분포하지 않았고 도관의 역할을하는 도관상 가도관이 있는 것으로부터 기주목 도관의 벽공과 겨우살이 가도관의 천공부가 결합하는 것으로 생각된다. 겨우살이 줄기의 구성세포 분포비율은 수령이 증가함에 따라 후벽세포의 분포비율이 높았다. 겨우살이 조직은 일반 목본식물에 비하여 유세포의 분포비율이 높고 세포내에 많은 내용물을 포함하고 있었다.
