  • Sinomegoura citricola (van der Goot, 1917) is recognized on Citrus unshiu Markovich (Rutaceae), Photinia glabra (Thunb.) Maxim (Rosaceae), and Cinnamomum lourelirii Nees (Lauraceae) from Jeju-do, Korea. Apterous viviparous female, alate viviparous female, and an intermediate morph between the apterous female and alate female are described. This is the first record of the genus Sinomegoura in Korea.

  • N. P. K는 감귤생산에서 가장 많이 사용되어지는 비료로서 이들 각각의 성분은 과실의 품질과 밀접한 관계가 있다. 그 중에서도 가리, 인산은 과실의 크기, 과피두께, 그리고 과실의 산도에 미치는 영향이 크다고 한다. 감귤의 착색촉진에는 제1인산 석회, 제1인산 가리의 엽면살포가 효과가 있다고 알려지고 있으며 최근에 이르러서는 하우스 재배의 토양수분 스트레스에 의한 세균 감소로 수세가 쇠약해지는 등 영양분의 결핍에 의한 생리장해를 예방하기 위하여 엽면시비가 증가하는 추세에 있다. (중략)

  • 온주밀감중에서 극조생 계통은 과육은 선숙되어도 착색이 되지않은 상태에서 출하되거나 수확후 에스렐 처리에 의해서 인위적으로 착색시켜 출하됨으로서 상품성이 떨어지고 있다. 고온에 의해 착색이 지연되어 수확이 늦어지는 감귤에 있어서도 상품성을 높이려고하는 차원에서 착색촉진에 관해 여러 가지 시험이 진행되어 왔다. (중략)

  • 여름철 고온기를 지나는 하우스 밀감은 착색이 되기 전에 과육이 선숙되는데, 일반적으로 착색은 고온에 의해 지연된다(Goldschmidt, 1988). 소비자들은 충분히 착색되지 않고 녹색을 띤 밀감은 성숙이 안된 것으로 생각하고 있기 때문에 수확 후 에테폰 처리에 의해 착색을 촉진시키고 있으나(Jimenez-Cuesta 등, 1983) 과경부의 꼭지가 쉽게 건조되고 짙은 오렌지색으로 발색되지 않고 연한 노란 색으로 되어 상품성이 높지 못하다. (중략)

  • Physicochemical properties and the conditions of cold storage of kiyomi clangor(Citrus unshiu x sinensis) produced in Cheju were investigated. Firmness, edible part ratio, soluble solids, and acid content were decreased gradually with incurasing fruit size. Carbohydrates in juice were consisted of 65.12% sucrose, 19.65% fructose, and 15.23% glucose The main organic acrid In juice was 57.4% of citric acid, and others were lactic acid, malic acid, oxalic acid and fumaric acid, respectively. Weight loss were occured very. slowly to about 6% till late of May, but decayed fruits were occurred very slowly to about 6% till late of May, but decayed fruits were arisen to about 8% at 3$^{\circ}C$, and about 13% at 5$^{\circ}C$ of storage temperature. The changes of peel moisture content, soluble solids, total sugar, vitaamin C, and density of fruits were slightly occured during cold storage. Cold storage at 3$^{\circ}C$ and 87% relative humidity kept freshness of citrus fruits for a long-term without damage of cold injury.

  • We investigated quality changes in Setoka ([Citrus unshiu$\times$Citrus sinensis]$\times$Citrus reticulate]$\times$[Citrus reticulata$\times$Citrus sinensis]) wrapped in 30-m pore size low-density polyethylene film (LDPE) and stored at different temperatures. LDPE wrapping effectively inhibited weight loss, and fruits seemed fresh even after room temperature storage. The decay rate was higher at room temperature and with LDPE wrapping. The respiration rate of LDPE- wrapped fruits was somewhat higher than that of control samples. Thus, no modified atmosphere packaging (MAP) effect was observed when 'Setoka' citrus was studied. Acidity decreased at a constant but different rate with each storage method used, and these rates were correlated with respiration rates. Soluble solid content (SSC), however, increased during 45 days of storage a subsequent rapid decrease was then observed.

  • This study was performed to investigate the effect of whole mandarin, peel, and pulp intake of Citrus unshiu Marc on the antioxidative capacity of 15-month-old rats. Forty-eight male Sprague-Dawley rats weighing 621.9 $\pm$ 10.1 g were separated into four groups according to body weight. The rats were raised with diets containing 5% (w/w) dried mandarin powder for four weeks. Three powders were used, consisting of mandarin peel, pulp, and the entire fruit. Total flavonoids, antioxidant vitamins and dietary fiber was highest in the mandarin peel powder, followed by the whole mandarin powder and the mandarin pulp. The body weight gains of the whole mandarin and mandarin pulp groups were higher, while that of the mandarin peel group was lower than that of the control group. Food intake and ratios of liver, kidney and epididymal fat pad (EFP) weights to body weight were not significantly different among the groups, but ratios of EFP weights per body weight of the experimental groups tended to be lower than that of the control animals. Plasma and liver TBARS concentrations decreased in all the mandarin groups compared to the control group. Plasma and liver xanthine oxidase (XO) activity decreased in all of the mandarin diet groups. Erythrocyte and liver SOD activity in all of experimental groups was not significantly different from the control group. Plasma vitamin A concentration increased significantly in all of the mandarin diet groups. That of the mandarin peel group was 4 times higher than that of the control group. Plasma total carotenoids and vitamin C level also increased in the mandarin peel group. Plasma vitamin I level was not significantly different among the groups.

  • This study was performed to investigate the effect of whole mandarin, peel or pulp intake of Citrus unshiu Marc. on antioxidative capacity and oxidative DNA damage in fifteen-month aged rats. Forty-eight male Sprague-Dawley rats $(621.9\;{\pm}\;10.1\;g)$ were blocked into four groups according to their body weights as control group, whole mandarin powder group, mandarin peel powder group and mandarin pulp powder group. Rats were raised with diets containing 5% (w/w) freeze dried mandarin formulations for four weeks. Total polyphenol content and total antioxidant status (TAS) of mandarin formulations were highest in peel powder, followed by whole powder and then pulp powder. The 8-hydroxy2'-deoxyguanosine concentrations of kidney in all mandarin groups were significantly lower than that of control group, and that of mandarin peel group was much lower than whole powder and pulp groups. Plasma TAS levels of all the experimental groups were higher than that of control group, and among mandarin groups, peel group showed higher level than remaining two groups. In conclusion, all the mandarin formulations were effective on antioxidative capacity in fifteen-month aged rats, and the peel was most effective one among three formulations.

  • 1. Objectives: This paper was written to understand the origin, changes and the constructive principles of Insamjinpi-tang(人蔘陳皮湯) 2. Methods: Insamjinpi-tang and other related prescriptions were analyzed in terms of pathology, based on "Dongyisusebowon Chobongwon(東醫壽世保元 草本卷)", "Dongyisusebowon Gabobon(東醫壽世保元 甲午本)", "Dongyisusebowon Sinchukbon(東醫壽世保元 辛丑本)", "Donguisasangsinpyeon(東醫四象新編)" 3. Results and Conclusions: (1) The origin of Insamjinpi-tang is Doksamyangbung-tang(獨蔘良崩湯), which is combination of Yijung-tang(理中湯), and Insamkeji-tang(人蔘桂枝湯) (2) The origin of Insamjinpi-tang was derived from Doksamyangbung-tang of "Dongyisusebowon Gabobon". Insamjinpitang greatly increases Ginseng Radix Alba(人參) when Insamjinpitang was compared with Yijung-tang, Insamkeji-tang. Insamjinpitang put to use Amomi Fructus(砂仁) newly first. (3) The Insamjinpitang composed of 5 herbs, Ginseng Radix Alba(人參), Zingiberis Rhizoma Crudus(生薑), Citrus unshiu (陳皮), Zizyphus jujuba(大棗) and Amomi Fructus(砂仁); Ginseng Radix Alba(人參) and Zingiberis Rhizoma Crudus (生薑) treat Taeumjeung(太陰證) of Soeumin(少陰人) through warming the Stomach(溫胃), Citrus unshiu(陳皮) makes the Yin(陰) downbearing, Zizyphus jujuba(大棗) making harmony between innerside and outerside of body and Amomi Fructus(砂仁) making stable one's mind.

  • Various extracts from 30 medicinal plants were evaluated for their antiviral activity against influenza virus A/Puerto Rico/8/34 (H1N1) and cytotoxicity in MDCK cell culture. The plant material (30 g) was extracted with methanol (300 mL) at room temperature for 24 h, after which the methanolic extracts were filtered, evaporated, and subsequently lyophilized. Evaluation of the potential antiviral activity was conducted by a viral replication inhibition test. Among these medicinal plants, Tussilago farfara, Brassica juncea, Prunus armeniaca, Astragalus membranaceus, Patrinia villosa, and Citrus unshiu showed marked antiviral activity against influenza virus A/H1N1 at concentrations ranging from 0.15625 mg/mL to 1.25 mg/mL, 0.3125 mg/mL to 10 mg/mL, 5 mg/mL to 10 mg/mL, 0.625 mg/mL to 10 mg/mL, 0.625 mg/mL to 10 mg/mL, and 0.3125 mg/mL to 5 mg/mL, respectively. The extracts of Tussilago farfara showed cytotoxicity at concentrations greater than 2.5 mg/mL, whereas the other five main extracts showed no cytotoxicity at concentrations of 10 mg/mL. Taken together, the present results indicated that methanolic extracts of the six main plants might be useful for the treatment of influenza virus H1N1.
