Rhapontica uniflora, Platycodon grandiflorum and Solanum tuberosum extracts affected the recovery of radiation-induced damage at all tested doses $(15.6,\;31.3,\;62.5\;and\;125\;{\mu}g/ml)$. The survival rate of pretreatment with extracts was increased by 2 times more than its compared with untreated cells. All tested extracts protected the growh-delay of normal cells and haematological parameters from their radiation-induced fall. In tested extracts, Solanum tuberosum was significantly superior to Platycodon grandiflorum and Rhapontica uniflora in radio-protection activity.

This study was carried out to obtain the basic information that can be used to index rhubarbs in six regions of China and Korea. The anthraquinone and stilbene contest in various rhubarb produced in th different area were quantitatively analysed by HPLC. The average of sennoside A content of the Chinghai rhubarb was higher than that of the other palmata rhubarbs(high-quality rhubarbs) produced in China. As a result, the order of the sennoside A content was 1) Chinghai rhubarb, 2) Tsuchan rhubarb, 3)Kansu rhubarb 4) Neimenggu rhubarb. On the other hand, the total stilbenes content of each of the cultivated Korean rhubarb(Rheum undulatum) were higher than that of the Chinese rhapontica rhubarb(low-quality rhubarbs).

Eleven out of 118 herbal medicines which are frequently used in Korean traditional prescriptions for inflammatory diseases exhibited more than 50% of inhibition on $TNF-{\alpha}$ production in LPS-stimulated RAW264.7 cells by their total ethanol extracts with 0.1 mg/ml as a final concentration. The active 11 total extracts were prepared from Angelica koreana, Coptis japonica, Cynanchum paniculatum, Magnolia frgesii, Magnolia officinalis, Panax ginseng, Patrinia scabiosaefolia, Pterocarpus santalius, Rhapontica uniflora, Saussurea lappa. Of them, Coptis japonica, Magnolia fargesii and Saussurea lappa also significantly inhibited $TNF-{\alpha}$ production in vivo. These total extracts were sequentially fractionated with n-hexane, methylene chloride, ethyl acetate, n-butanol and water. Among the solvent-fractionated extracts with 0.05 mg/ml as a final concentration, inhibitory effects of Angelica koreana, Magnolia fargesii, Magnolia officinalis, Pterocarpus santalinus, Rhapontica uniflora and Saussurea lappa markedly showed in one or two solvent fractions suggesting that the principles may be concentrated by subfractionation as the main compounds.

연구에서는 산채류 34종의 물 추출물과 메탄올 추출물을 제조한 후 항산화 활성을 탐색하여 산채류 유래 항산화물질을 탐색하고 기능성식품을 개발하기 위한 항산화능 우수 산채류 선발의 기초 자료를 제공하고자 하였다. 산채류시료 34종을 물과 메탄올 추출하였을 때 추출 수율은 물 추출의 경우 4.6~34.6%이었고, 메탄올 추출의 경우 3.4~45.0%이었다. 총 폴리페놀 함량은 물 추출물에서 4.6~183.8mg/g이고, 메탄올 추출물에서 8.2~270.4 mg/g이었다. 물과 메탄올 추출물에서 돌단풍(Aceriphyllum rossii )이 각각 183.8, 270.1 mg/g의 가장 높은 폴리페놀 함량을 보였고, 공통적으로 광대싸리(Securinega suffruticosa), 기린초(Sedum kamtschaticum), 까치수영(Lysimachia barystachys), 송이풀(Pedicularis resupinata)이 높은 폴리페놀 함량을 보였다. DPPH와 ABTS 라디칼 소거능은 까지수영, 돌단풍, 광대싸리, 기린초, 송이풀(Pedicularis resupinata), 승마(Cimicifuga heracleifolia), 짚신나물(Agrimonia pilosa), 뻐꾹채(Rhapontica uniflora)에서 우수하였다. 변수간의 상관성을 분석했을 때, 폴리페놀 함량과 DPPH 및 ABTS 라디칼 소거능, SOD 유사활성 사이에는 유의적인 양의 상관관계가 있었으며, 이들 측정치에서 공통적으로 우수한 것으로 조사된 산채류는 송이풀, 광대싸리, 뻐꾹채, 까치수영, 돌단풍이었다.

Rhubarb (Rhei Rhizoma) has been used for the various clinical purposes such as purgative, stomach protective and pain relief for a long time. However, rhubarb in current market has a problem of quality control under which many of rhubarb fail to meet the standard specified in Korean Pharmacopoeia. This study was carried out to validate the method for the evaluation of the quality of five rhubarbs and Rumex species; Rheum palmatum, R. officinale, R. tanguticum, R. franzenbachii, R. undulatum, and Rumex species. The content of sennoside A with five anthraquinones (aloe-emodin, rhein, emodin, chrysophanol and physcion) in five rhubarbs and one Rumex has been performed by using HPLC quantitation analysis. In results, only four samples in Palmata sect. were qualified with sennoside A and those samples were R. officinale and R. tanguticum. Samples of R. palmatum did not meet the standard contents of sennoside A. The contents of anthraquinones in Palmata sect. were two times larger than those in Rhapontica sect. Moreover the content variations of anthraquinones were smaller than those of sennoside A. Thus, anthraquinones can be the key characterizing molecules to control quality of rhubarb.

본 연구는 인천 송도임해매립지를 대상으로 자원식물상과 귀화식물을 조사함으로써, 매립이후 식물상과 식생 변화를 모색하고 자원식물 개발을 위한 기초 자료를 제공하고자 수행한 결과 다음과 같다. 송도임해매립지에서의 식물상은 39과 113속 144종 23변종 2품종 1교잡종으로 총 170종류가 확인되었으며, 이중 목본식물에는 18종류(10.6%), 초본식물에는 152종류(89.4%)로 분석되었다. 자원식물 중 식용식물에는 107종류(62.9%), 약용식물에는 99종류(58.2%), 관상용식물에는 55종류(32.4%), 기타용에는 77종류(45.3%)로 분석되었다. 식물구계학적 특정식물에는 IV등급에 들완두, III등급에 모감주나무, I등급에 장구밥나무, 진퍼리까치수영, 뻐꾹채 등 총 5종류가 확인되었으나, V등급과 II등급에 포함되는 특정식물은 출현하지 않았다. 염생식물(사구식 물 포함)에는 갈대, 새섬매자기, 칠면초, 갯개미자리, 큰개미자리, 모감주나무, 장구밥나무, 왕질경이, 비쑥, 사철쑥, 쇠채, 사데풀 등 총 12종류가 확인되었다. 귀화식물에는 11과 27속 37종 1변종으로 총 38종류가 확인되었으며, 귀화율은 총 170종류의 관속식물 중 22.4%로 분석되었다.
