Sixty medicinal and food plants native to Korea were mainly selected with old traditional habit and antioxidant activity was investigated. The 80% EtOH extracts of sixty medicinal and food plants were screened for antioxidant activity. Antioxidant activity was measured by the TBA (Thiobarbituric acid), DPPH (1, 1-Diphenyl-2-picrylhydrazyl), SOD (superoxide dismutase) which was evaluated by the nitro blue tetrazolium(NBT) reduction method. Among sixty plants, black Glycine max(87. 3%) and Solanum nigrum (80.6%) exhibited the highest antioxidant activity by TBA and DPPH methods, respectively. Also, 10 species extracts including black Glycine max showed the high activity value in these two methods. The SOD characteristics on black Glycine max seed extracts which showed the highest SOD activity (53.5%) exhibited four major SODs; two Cu/ZnSODs and two FeSODs. However, Adenophaora vertidllata which showed lowest SOD value (10.4%) had only Cu/Zn SOD. No varietal differences in the high SOD value were detected in the Cu/Zn SOD isozyme patterns.

This study was conducted to screen antitumoral activity by in vitro bioassay method using 60 Korean medicinal and food plants extracted by 80% EtOH. Antitumor activity test was applied by the PKC(protein kinase C) and antibleb formation, PLC (Phospholipase C), and colorimetric tetrazolium assay (MTT assay) methods. Chenopodjum album and black Glycine max showed high antitumoral activity by 73.5% and 81.0%, respectively, against PKC by bleb-forming assay and PKC enzyme assay on human chronic leukemia K562 cell. Black Glycine max also showed 91.2% antitumoral activity in the PLC method and the lowest $IC_{50}$ $value(4.7{\mu}g/ml)$ by MTT method against P-338 cell line. In the effect of the concentration treatment on antitumoral test, the more concentration indicated the more activity value.

This study was conducted to obtain the basic information of edible resources among plant species. Potentials of resource plants were important in various usages, healthy food, medicinal materials, and breeding materials. Through our investigation 609 species of resources plants were considered as edible resources. These species belong to 74 families in which Asteraceae, Poaceae, Fabaceae, and Rosaceae were major families. Brassicaceae, Liliaceae, and Asteraceae contained large numbers of edible plants because plants belonged to these families were mainly used as vegetable. But Cyperaceae and Poaceae had relatively small numbers of species in the category of edible plant because plants belonged to these families have not been used directly as vegetables, common usage of edible plant. But Poaceae have a potentials as genetic donor for resistance-breeding strategies in major cereals. Although Poaceae can not be used as food directly, Poaceae should be investigated intensely in future for improvement of major cereals or application as fodder plants. The beneficial traits of edible plants as breeding materials have not been studied yet and development of new crop from plant resources requires the information about current situation in occurrence of resources plants genetically related to current crop species. Our results do not cover all plant species in Korea but this classification and identification about edible resources will provide primary information about plant resources. The collected seeds of resource plants showed wide spectrum in germination rate among plant species. The germination rate would probably be affected by collecting times, collected stage, and stored period. The proper methods about improving germination rate have to be elucidated to propagate the resource plants.

To analyze the pesticide residues in commercial bee pollen products in South Korea, 61 samples were collected and screened for 339 pesticides. Results revealed that approximately 34% (>LOQ) of samples were contaminated with at least one pesticide. The pesticide residue detection rates of domestic and imported samples were 31% and 44%, respectively. Furthermore, the pesticide residue detection rate of online distribution (60%) was higher than that of offline distribution (27%). Fifteen pesticides were discovered in bee pollen, and pendimethalin, chlorfenvinphos, chlorpyrifos, and fluazinam were detected in 7, 6, 3, and 2 order of frequency, respectively. Even though its concentration was low, chlorfenvinphos which is banned in food crops in the United States, European Union, and Korea, was detected in bee pollen samples commonly. Therefore, continuous investigation of pesticide residues in bee pollen products and their acceptance criteria is required for safety.

국민소득 증가에 따른 식생활문화의 향상으로 식용유 소비추세는 날로 증대되는 경향이다. 수요충족을 위한 도입량 증가추세가 생산량보다 훨씬 큰 반면 국민건강을 위해서도 양질식용유의 공급증대는 필수적이다. 이같은 문제를 진단하고 전망해본 <유료작물의 생산$\cdot$가공기술과 전망>에 관한 심포지엄이 지난해 11월 16일 작물시험장 강당에서 개최되었다. 그 주요내용을 간추려 소개한다.

This paper aims to provide the basic data about the uses of agricultural products related to food, cloth and shelter in the late Joseon Dynasty by analysing$\ulcorner$Kyuhap-Chongseo$\lrcorner$(1809). The results of this study are as follows: 1. The agricultural products related to cloth, food and shelter were of 95 species total(horticultural crops 37.9%, industrial crops 22.1%, food crops 13.7%, floricultural crops 13.7%. and animal products 12.6%). 2. The agricultural products(24species) related to clothing were used for weaving, dyeing, laundering and starching textiles. 80 species of agricultural products were used as ingredients in about 140 dishes. As for shelter, the agricultural products(30species) were used for making stationaries. managing vessels and illumination, and building structures.
