이봉호,문윤호,정병춘,김관수,류수노 한국국제농업개발학회 2002 韓國國際農業開發學會誌 Vol.14 No.2

기능성식품 원료, 채소, 식물성 소금 재료 및 제염식물 등으로 개발이 유망시되는 염생식물인 나문재의 육지부 재배 가능성을 조사하고, 내륙지방에서의 작물화 가능성을 검토코자 전남 서해안의 염전 부근에 자생하는 나문재의 종자와 식물체를 공시하여 내륙지방인 전남 무안군 소재의 『목포시험장』포장에서 시험하였던 바 그 결과를 요약하면 다음과 같다. 가. 나문재는 식물체를 이식하여도 생육이 양호할 뿐만 아니라 2년 묵은 종 자에서도 발아가 잘되었으며 발아소요 기간은 9일 정도 였고, 나문재의 생육은 소금기가 부족한 내륙에서도 비교적 양호하였으며, 병충해나 기타 재해도 거의 없어 내륙에서의 재배화 가능성이 높은 것으로 인정되었다. 나. 나문재의 생육에 미치는 소금물의 공급 효과를 검토하기 위해 1주일 간격으로 바닷물 농도의 소금물을 공급한 결과, 초장은 소금물을 공급한 것이 공급하지 않은 것 보다 양호하였으나 줄기의 굵기와 분지발생 수 는 소금물 공급효과가 크지 않았다. 다. 나문재의 생체중과 건물중은 종자파종의 경우 7월 10일 현재 소금물 처리구는 각각 주당 33.75g, 2.62g인데 비해 무처리구는 각각 23.52g, 1.84g으로서 소금물 처리구가 무겁고, 생체중에 대한 건물중의 비율은 대체로 7.14∼11.58% 범위로서 수분함량은 92.86∼88.42%정도 되는 다육식물 이었다. 라. 결론적으로 나문재는 소금기가 많은 곳에서 잘 생육할 뿐만 아니라 소금 기가 적은 곳에서도 생육이 비교적 양호하며, 식물전체에 짠맛을 가지고 있으므로 식물성 소금, 기능성 식품, 채소, 그리고 간척지나 음식물쓰레기의 염분제거 식물로서의 이용 가능성 등에 대한 보다 면밀한 검토가 필요하다고 보여진다. The plant of halophyte, Suaeda asparagoides MIQ, which is mainly inhabit on tidal flat was investigated on their growth characteristics and cultural traits on inland condition, in order to get some informations on it's possible use for functional food, vegetables, medicinal herb, and salt removing plant from tideland, or food-waste. The plant, Suaeda asparagoides M_IQ., is well grown on inland condition. But the salt applicated plants were better than those of the non-treated plants in its vegetable growth. The plant height is about 78.5cm in salt application, compared to the 64.5cm in non-treated plot. But the stem diameter and the number of branches are not better in salt application compared to the non-treated ones. However, the fresh weight and dry weight of the plant in salt-application are better than those of the non-treated ones, which means the total biomass is more productive by the salt application. As a conclusion, the plant Suaeda asparagoides M_IQ, seems to be an available plant and need to more discussion for possible use mentioned in the above sectors, from the results of inland cultivation of which well grown and characteristics.

Su-Noh Ryu,Sun-Zik Park,Hong-Yeol Kim 韓國作物學會 2002 Korean journal of crop science Vol.47 No.1

The antioxidant activities of methanol extracts of sixteen samples were tested using 1.1-diphenyl-2-picryl hydrazyl(DPPH) reactivity and TBARS substances assay in vitro. The methanol extracts of the rice brans from three wild rice -O. minuta, O. rufipogon, and O. barthii-were found to be the most effective in DPPH radical scavenging activity. The next effective ones were the rice brans of Heugjinjubyeo and leaves of Tapgolbori. When tested on lipid peroxidation using a lipid peroxidation generation system mediated by H2O 2 /Fe2+ in rat liver homogenates, the brans and hull of wild rice (O. minuta, O. rufipogon, and O. barthii) and rice bran of Heugjinjubyeo exhibited protective activities against lipid peroxidation in the order of effectiveness.s.

Quatitative Determination of Sesaminol Glucosides in Sesame Seed

Su-Noh Ryu,Kwan-Su Kim,Jin-Ki Bang,Bong-Ho Lee 韓國作物學會 1998 Korean journal of crop science Vol.43 No.4

The sesaminol glucosides in 80% EtOH extract from sesame seeds were separated by high performance liquid chromatography (HPLC). A HPLC system using a Develosil ODS-5 column and gradient elution system from 30% to 80% methanol was selected for separation and quantitative determination of sesaminol triglucoside, sesaminol diglucoside, and sesaminol monoglucoside. Quantitative analyses for these sesaminol glucosides, sesaminol triglucoside, sesaminol diglucoside, and sesaminol monoglucoside were determined on the basis of standard curve of sesaminol glucosides. Sesaminol triglucoside, sesaminol diglucoside and sesaminol monoglucoside contents of the seed of one Korean sesame cultivar, Danbaekggae, were 56.4 mg/100g, 9.6 mg/100g, and 7.5 mg/100g, respectively. The most abundant aglycon of lignan glucosides in sesame seed was sesaminol triglucoside

Determination of C3G Content in Blackish Purple Rice using HPLC and UV-Vis Spectrophotometer

Su Noh Ryu,Sun Zik Park,Sam Sik Kang,Sang Jun Han 韓國作物學會 2003 Korean journal of crop science Vol.48 No.5

Cyanidin 3-glucoside (C3G) content contained in the grains of blackish purple rice varieties, Heugjinjubyeo, Kilimheugmi, Heugnambyeo, Sanghaehy-anghyeolla, and the progenies derived from their crosses was evaluated by HPLC and UV-Vis spectroscopy. C3G content was higher in the range of 10-30% by using UV-Vis method compared to HPLC method. A significant linear relationship was, however, observed between two analytical methods. The correlation coefficient was 0.98. Thus, this results suggested that it would be able to use UV-Vis spectroscopy to determine C3G content which does not demanded precise value like selection.

Su Noh Ryu(柳守魯),Jung Il Lee(李正日),Chul Whan Kang(姜哲煥) 한국육종학회 1995 한국육종학회지 Vol.27 No.3

This study was conducted to obtain basic informations on the unsaponifiable components in sesame seed. Four major lignan, sesamin, sesamolin, sesamol and sesangolin were analyzed to provide fine separation of unsaponifiable component fractions of seed oil in four wild and three cultivated sesame varieties by thin layer chromatography (TLC). The mean content of unsaponifiable components extracted from cultivated sesame oil was 2.4% (ranged 2.2 to 2.7), while that of wild ones showed 3.3% (ranged 2.3 to 4.0). The mean content of unsaponifiable components of wild species was higher than that of cultivated ones. Silicagel plates and chloroform/diethyl ether (9 : 1, v/v) as mobile phase on the first and second directions were utilized in TLC analysis. In one-dimensional TLC separation, sesamin, sesamolin, sesamol, sesangolin and tocopherol were identified as spots at the Rf values of 0.66, 0.76, 0.52, 0.66 and 0.88, respecitively. Sesamin and sesangolin were appeared at same spots with Rf value of 0.66. In two-dimensional TLC separation, sesamin and sesangolin showed different TLC pattern. This two-dimensional system could be adopted to provide pure fractions in preparative experiments for sesamin and sesangolin measurements of seed oil. Some other minor spots were also observed in S. alatum and S. radiatum showing void of sesamolin but containing sesangolin.

Antioxidative Activity and Varietal Difference of Cyanidin 3-glucoside and Peonidin 3-glucoside Contents in Pigmented Rice

Su Noh Ryu,Sang Jun Han,Sun Zik Park,Hong Yeol Kim 韓國作物學會 2000 Korean journal of crop science Vol.45 No.4

The content of anthocyanin, cyanidin 3-glucoside (C3G) and the peonidin 3-glucoside (P3G) from 591 rice cultivars and the antioxidative activities of MeOH extract from 8 rice cultivars were evaluated. Among them, C3G content of pigmented rice were ranged from 0 to 451.9mg in 100 g brown rice, while the P3G contents were in the range from 0 to 42.7mg in 100g brown rice. There was no correlation between C3G and P3G content. Total anthocyanin content ranged from 0 to 475.1mg in 100g brown rice. The antioxidative activity, the scavenging activity on DPPH (2,2-diphenyl-picryl-hydrazyl) radical of MeOH extracts from rice grain, were different according to cultivars. The activity of blockish purple pericarp rice cultivars was twice stronger than that of white pericarp cultivar. Especially, the antioxidative activity of Heugjinjubyeo was four times stronger than that of white pericarp cultivar. The scavenging effect on DPPH radical in rice extracts was related to the total anthocyanin contents of the extracts.

Volatile Oil Composition of Boxthorn (Lycium chinense M.) Leaves

Su-Noh Ryu,Seong-Min Kim 韓國作物學會 1998 Korean journal of crop science Vol.43 No.3

Volatile components were extracted from leaves of two Boxthorn (Lycium chinense M.) cultivars by using simultaneous distillation and extraction, analyzed by gas chromatography-mass spectrometry. Seventy components were identified : 13 acids, 15 alcohols, 18 hydrocarbons, 13 carbonyls, three esters, three ionones, and five others. The principal volatile components (and their peak area percentage) were n-pentanol (11.2~30.2%), phytol (14.5~28.3%), hexadecanoic acid (13.5~17.1%) 2,3-dihydrobenzofuran (1.5~4.2%), benzyl alcohol (1.9-4.8%), phenylacetaldehyde (1.8~3.2%), and octadecadienoic acid (1.7~10.7%). Fresh leaves showed much higher peak area than that of dried leaf in n-pentanol, n-hexanol, cis-2-penten-l-ol, cis-3-hexen-l-ol, benzyl alcohol, and β -phenylethyl alcohol, while dried leaves showed much higher content than that of fresh leaves in 9-hydroxytheaspran A, octadecanoic acid and octadecadienic acid.
