작약의 이용성을 높이기 위해 작약의 종 및 품종, 생육시기, 식물체 부위별 성분의 함량 분포와 변화를 HPLC를 이 용하여 분석한 결과를 요약하면 다음과 같다. 작약의 종 및 품종간 성분의 함량 분포는 야생작약(P. japonica M., P. obovata M., P. anomala L.) 보다는 재배작약(태백작약, 의성작약)에서 전반적으로 함량이 더 높았고, 성분별 분포는 paeonifloin, methyl gallate, astragalin, kaempferol 순으로 높았으며 methyl gallate 는 의성작약에서 0.45%로 가장 높았다. 식물체 부위별 함량 분포는 methyl gallate는 꽃잎에서 1.79%로 가장 높았으며 잎에는 0.56% 함유하였고, 뿌리에는 0.01%로서 소량 분포하였다. Astragalin 은 꽃잎과 잎에서 높았고, 작약의 지표 성분인 paeoniflorin 은 뿌리에서 2.52%로 가장 높았으며 잎에도 1.09%나 함유하여 이용 가치가 매우 높다고 사료된다. 생육시기별 함량 분포는 생육초기인 4월에 가장 높았고 생육 후기로 갈수록 감소하는 경향이므로 잎과 줄기를 이용하려면 뿌리 수확직전인 8~9 월이 적기라고 생각된다.

본 연구는 3종류의 약용식물(당귀, 목통, 골담초)을 물과 에탄올로 추출하여 전자공여능과 아질산염 소거능을 조사하여 건강 식품의 제조에 필요한 기초자료를 얻고자 하였다. 3종류의 한약재중 물추출물의 수율은 목통()>골담초()>당귀()의 순이었으며 에탄을 추출물의 수율은 목통()>당귀(), 골담초()의 순으로서 목통이 가장 높은 수율을 나타내었다. 한약재 추출물의 전자공여능은 물추출물 300-1,000 ppm에서 당귀가 로 가장 높았으며, 에탄

The effects of topping method on the yield and major agronomic traits of two varieties, Sunwol and Youngjun of Alisma plantago, were investigated in the Southern region.

Considering from our results, optimum topping method is most likly be topping of four times cutting in flowering in main culm in the Sunwol variety.

생약재의 용매별 추출액에 대한 생리활성 측정 결과 총폴리페놀 함량은 모든 생약재가 50 ethanol 추출액에서 가장 우수하였으며, 생약재 별로는 감초의 50 ethanol 추출액이 2.23로 가장 높은 함량을 나타내었다. 전자공여 작용은 감초 water 추출액이 81.81로 가장 우수하였으며, 감초, 건강는 water 추출액이 두충, 건마늘, 인삼은 50 ethanol 추출액에서 다른 용매에 비해 높은 전자공여 효과를 나타내었다. Superox

The experiment was conducted to evaluate the effects of medicinal plants on ethanol-metabolism. Sprague Dawley rats divided into 6 groups (n=8), fed with 10% ethanol and diets supplemented with each 1% of four plant extracts, α-tocopherol (as positive control) and fiber (as negative control) for 4 weeks. Group supplemented with plant extract of Ulmus davidiana showed the most high value (322 nM NADH/min/mg protein) in alcohol dehydrogenase (ADH) activity among the experimented groups (144~312 nM NADH/min/mg protein) at p〈0.05. Groups fed with Lagerstroemia indica and Zelkova serrata extract-supplemented diets indicated high activity in aldehyde dehydrogenase (ALDH, 16.7 & 12.3 M NADH/min/mg protein), which were comparatively lower than 20.1 M NADH/min/mg protein of α-tocopherol fed group. All of the groups fed with plant extracts indicated very low GPT activities (13.9~17.3 IU/l) compared to those (146.1 & 128.6 IU/l) fed with α-tocopherol and fiber at p〈0.05. From these results, it is suggested that Lagerstroemia indica have a potent ethanol-metabolizing activity.

Four medicinal plants selected from preliminary screening study were evaluated in the aspects of their antioxidant activities in alcohol-intoxicated rats. Rats fed 1% α-tocopherol-supplemented diet as positive control and ones done α-tocopherol-deficient diet as negative control were compared with ones done the plant extract-supplemented diet (n=8). After the administration of the experimental diets for 4 weeks, typical increments in activities of manganese-superoxide dismutase (Mn-SOD) and glutathione peroxidase (GSH-px) indicated in alcohol-intoxicated rats, were not observed in ones fed Lagerstroemia and Ulmus extract-supplemented diet. The content of thiobarbituric acid reactive substance (TBARS), the product of lipid peroxidation, did not increased in rats fed plant extracts-supplemented diet except for Terminalia. From the results, it is concluded that Lagerstroemia and Ulmus have physiologically efficient antioxidant activities.

Medicinal plants were screened for the inhibitory effects on human immunodeficiency virus type 1 pretense. Of the extracts tested, the strong inhibitory effects were observed in the acetone extracts of the pericarp of Camellia japonica. Camelliatannin H from the pericarp of C. japonica showed a potent inhibitory activity on HIV-1 pretense. Effects of the extract and compound from leaves of Zanthoxylum piperitum on the enzyme activities were investigated in the liver of bromobenzene-treated rats. The methanol extract and protocatechuic acid isolated from Z. pipetitum reduced the activity of aniline hydroxylase that increased by bromobenzene, while did not affect the activities of aminopyrin N-demethylase and glutathione S-transferase. The extract and protocatechuic acid recovered significantly the activity of epoxide hydrolase decreased by bromobenzene.

Coleus forskohlii Briq, of the family Lamiaceae yields a valuable secondary metabolity known as forskolin which is a labdane diterpenoid.. Coleus forskohlii is the only known source of this compound. Forskolin is used in medicine for the treatment of glaucoma, congestive cardiomyopathy and asthma. Morphogenic callus was induced from young leaves on MS medium augmented with NAA and BA. These calli, when subcultured on MS with KN alone gave rise to shoots. The regenerated shoot developed good root system on MS medium fortified with NAA. The fully grown plantlets were transferred to soil for acclimatization. Coleus plant is mainly infected by a fungi Lasiodiplodia theobromae which causes root rot disease. The fungal culture filterate (ECE) of Lasiodiplodia theobromae, has been used in regeneration media to find the MIC and further to select resistant plants to the pathogen. In the present study 40% ECF in the medium showed maximum inhibition and is there fore considered as the MIC level of Coleus forshohlii. This data could prove to be useful for the future for selecting a resistant C.forskohlii plant against the root disease caused by L. theobromae.

This expriment was carried out to get basic information on composition and yield of aromatic constituents in leaves of four medicinal plants, Angelica tenuissima, Chrysanthemum zawadskii. ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris. Volatile aromatic constituents, 28 compounds in Angelica tenuissima were identified and 19 compounds were indentified in Chrysanthemum zawadskii ssp. latilobum. Volatile aromatic constituents, 23 compounds in Artemisia iwayomogi and Artemisia capillaris were identified. Major volatile aromatic consitiuents analyzed by GC/MS in four plants were α-pinene, camphene, sabinene, cis-2-hexanol, and camphor etc. Content of essential oils in Angelica tenuissima, Chrysanthemum zawadskii ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris were 0.014, 0.275, 0.785, and 0.452%, respectively. As a result, it was suggested that a medicinal plant, Artemisia iwayomogi, was worthy of using as a useful material of perfume.

The development of medicinal plants for cut plants and landscape plants were conducted through the literiture survey. The results were as follows: We selected 38 species of medicinal plants including 7 medicinal woody plants for cut plant and landscape plants from 450 medicinal plants. There were 8 species of Compositae, 4 species Ranunculaceae, 3 species Rosaceae and Umbelliferae, 2 species Polygonaceae and Campanulaceae respectively. The anthesis of Cornus officinalis, Magnolia denudata, Forsythia koreana of medicinal woody plants flowering before leaf spreading come to early than the anthesis of other medicinal plants. There were 4 species(11%) over 10cm of the flower diameter, 6 species(16%) over 5cm below 10cm, 19 species(50%) over 1cm below 5cm and 9 species(24%) 1cm below. In terms of flower color, 11 species(29%) were white, 9 species(24%) yellow, 6 pecies(16%) red, 5 species(13%) violet and 3 species(8%) were blue aided violet. In terms of the flowering by month, 12 species(32%) on July, 9 species(24%) on May, 6 species(16%) on June and August respectively, and 3 species(8%) on March. The most medicinal plants were propagated by division and seeding easily, but woody medicinal plants of 7 species of this study were propagated by cutting and grafting easily. The percentage of usage of parts of medicinal plants including woody medicinal plants was that roots were 20 species(53%), flowers 6 species(16%), fruits and all part of medicinal plants were 4 species(11%), and seeds and stem including leaves 2 species(5%) respectively.
