  • Two naturalized species, Chaerophyllum tainturieri Hook. (Umbelliferae) and Barbarea verna (Mill.) Asch. (Cruciferae) were newly reported from South Korea. C. tainturieri., 'Jeon-Ho-A-Jae-Bi', was found at World Cup park in Sangam-dong, Mapo-gu, in Seoul, and the genus Chaerophyllum is reported for the first time from South Korea in the present paper. It is distinguished from the genus Sphallerocarpus by having cylindrical fruit, and each furrow with one vitta. B. verna, 'Bom-Na-Do-Naeng-I', was found on a riverside area of Suyeong River, Geumsa-dong, in Busan. It can be distinguished from B. orthoceras by silique 4-8 mm long , seeds 1-2 mm long, and basal rosette leaves with a 4-11 large pairs of lateral lobes.

  • Five compounds were isolated from the whole plant of Arabis glabra (Cruciferae) through repeated silica gel and Sephadex LH-20 column chromatography. Their chemical structure were elucidated as salicylic acid, 2,5-dihydroxybenzoic acid, astragalin, rutin, and $quercetin-3,7-O-{\beta}-D-diglucopyranoside$ by spectroscopic analysis.

  • In the course of our search for anti-Herpes simplex virus type I (HSV 1) substances from natural sources, we screened crude drugs for their antiviral activity using SRB assay. T he methanol extract from herb of Brassica rapa (Cruciferae) was found to inhibit HSV-1. Though bioassay-directed fractionation of the extract, anti-HSV-1 agent was isolated by chromatographic separation using Amberlite XAD-4 and Sephadex LH-20. The structure of compound I was elucidated by spectral means including $^1H-^1H$ COSY, HMQC and HMBC to be isorhamnetin 3-O-${\beta}$-D-glucopyranoside (compound I). Compound I was active against HSV-1 with the 50% effective concentration of O.42mg/ml and the 50% cytotoxicity of 5.0mg/ml.

  • 유채(Brassica napus L.)는 식용유 생산을 목적으로 재배되며, 1975년에는 26.8천ha가 재배되어 연간 생산량이 34.7천톤이 생산되었으나, 외국으로부터 값싼 식용유의 대량수입으로 재배면적이 급격하게 감소되었다. 그러나 최근에 지방자치단체를 중심으로 경관용 재배면적이 증가하고 있고, 건강에 대한 관심이 높아짐에 따라 국내산 non-GM 식용유 생산을 목적으로 유채 재배면적이 급격하게 증가하고 있다. 유채의 대량생산을 위해서는 논 재배가 필수적이나 유채와 벼의 이모작 재배 시기가 겹치는 문제점이 발생하고 있어 조생종 유채의 품종개발과 함께 봄 파종이 가능한 유채의 품종 육성에 대한 요구가 매우 높다. 따라서 본 연구에서는 국내 보유 유채를 포함하는 십자화과(Cruciferae) 유전자원의 특성 평가를 통해 극조숙 유채 품종 육성을 조기에 육성하기 위해 실시하였다. 농촌진흥청 국립유전자원센터에서 분양받은 유전자원 146계통을 파종 재배하면서 핵형분석과 외부형질을 기준으로 정확한 종을 동정하였고, 각 유전자원의 생육 및 개화특성을 조사하였다. 유전자원들을 세포분석기를 이용하여 핵형을 분석한 결과, 전체 146개의 유전자원 중 유채(B. napus L.) 128계통, 갓(B. juncea Sinsk) 6계통, 배추(B. campestris Makino) 9계통, 미분류 3계통 등으로 조사되었다. 유전자원을 가을 파종(10월 22일)하였을 때 개화가 가장 빠른 계통(IT 279089)이 파종 후 137일 이후인 3월7일부터 개화가 시작되었고, 가장 늦은 계통(IT 279198)은 191일 후인 4월 30일에 개화가 시작되었다. 봄 파종(2월 4일)하였을 때 개화가 가장 빠른 계통(IT 279089)이 파종 후 79일 이후인 4월 23일부터 개화가 시작되었고 IT 279092 등 29계통은 추대와 개화가 되지 않았다. 위와 같은 연구결과를 토대로 개화시기가 빠른 유전자원을 육종을 위한 인공교배 시화분친이나 종자친으로 이용하면 지방산 품질이 좋고 극조숙성인 유채 품종의 개발이 가능할 것으로 생각된다.

  • Three flavonoid glycosides have been isolated from the aerial part of Armoracia rusticana P. (Cruciferae) in Korea and identified by means of spectral analysis as $kaempferol-3-O-{\beta}-D-xylofuranoside(l)$, $kaempferol-3-O-{\beta}-D-galactopyranoside(2)$ and $kaempferol-3-O-{\beta}-D-xylofuranosyl(1\rightarrow2)-b{\beta}-D-galactopyranoside(3)$. When 1 mg/ml of the methanol extract from the aerial part of this plant was added, lipid peroxide formation in the bromobenzene-treated rat liver decreased by 64%. Among the components isolated from title plant, compounds 2 and 3 reduced the formation of lipid peroxide by 16% and 39% respectively at the concentration of ${10}^{-1}$ mg/ml.

  • This study was conducted to develop the suitable nutrient solutions for variable Cruciferae leafy vegetables. l/2, 1 and 3/2 strength of nutrient solution recommended by National Horticultural Research Institute were supplied to plants in deep flow technique systems during 25 days. The growth of pak-choi and leaf mustard 'Asia curled' was highest in the 3/2 strength, and kaie 'TBC' in the 1 strength. Mean cation ratio of nutrient solution for pak-choi, leaf mustard and kale was K $49.5\%$, Ca $35.8\%$ and Mg $14.7\%$, which was obtained by calculating the uptake rates of water and nutrients. Suitable composition of the nutrient solution for Cruciferae leafy vegetables was N 14, P 3, K 6.8, Ca 4.8, $Mg 2m{\cdot}L^{-1}$. To examine the suitability of nutrient solution developed for Cruciferae vegetables (NSC), plants were grown 4 times from Sep. 2003 to Oct. 2004. When plants were grown in NSC, relative growth rate increased 1.1 to 2.5 times and vitamin C content 1.06 to 1.52 times. The proper plants to apply NSC for functional leaf vegetable production were leaf mustard 'Asia recurled', 'Redcurled' and 'Pamagreen', kale 'TBC', 'Portugal' and 'Hanchu collard', leaf broccoli 'New green', pak-choi, baby cabbage 'Red king' and 'Green king', flowering red chinese cabbage and Korean cabbage.

  • Cucurbitacins are a natural cell-permeable triterpenoid compound isolated from Cucurbitaceae and Cruciferae. Cucurbitacins have been used as folk medicine because of their anti-inflammatory and analgesic effects. In the present study, we investigate the anti-cancer effects of cucurbitacin I on colitis-associated colon carcinogenesis induced by azoxymethane (AOM)/dextran sodium sulfate (DSS) in BALB/c mice. Cucurbitacin I treatment attenuated loss of body weight and decreased the number of colon tumors. Western blot analysis showed that cucurbitacin I treatment significantly inhibited the protein expression of inducible nitric oxide synthase (iNOS), tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-6. These results suggest that cucurbitacin I suppressed inflammatory reaction and tumor development in colitis-associated colon carcinogenesis.
