In the edible parts of chinese cabbage, the NO-3 accumulation was higher in the outer leaves than in the inner leaves and it was higher in the leaf midrib than in the leaf blade. In Radish, it was higher in the aerial part of the root than in the underground part of root. NO-3 accumulation in edible parts of chinese cabbage of organic farming fertilized with compost 8t/10a was about 4 times higher than those of conventional farming with recommended mineral nitrogen; and was similar to those of conventional farming fertilized with twice the mineral nitrogen rate. But, NO-3 accumulation in radish of organic farming with 8t/10a compost was lower than those of conventional farming with recommended mineral nitrogen. It showed NO-3 content in the edible parts of vegetables should be considered one of several parpmeters to judge a real safety vegetable to be certified by government.

기능성식품 소재를 개발하기 위한 연구의 일환으로 야생 산채류인 우산나물의 지상부와 뿌리 추출물에 대한 플라보노이드와 폴리페놀 화합물 함량 그리고 생리활성 효과를 측정하였다. 플라보노이드는 지상부 에탄올 추출물이 31.72 mg/g으로 가장 많았으며, 폴리페놀은 뿌리의 에탄올 추출물에서 68.11 mg/g으로 가장 높았다. Xanthine oxidase에 대한 저해 효과를 측정한 결과 1.0 mg/mL의 농도에서 지상부 물 추출물과 뿌리의 에탄올 추출물 모두 98% 이상의 저해율을 보였으며, tyrosinase 저해는 뿌리 에탄올 추출물에서만 9.33%의 저해효과를 나타내었다. 우산나물 뿌리의 에탄올 추출물은 pH 1.2의 조건에서 70.89%의 아질산염 소거능을 보였으며, SOD 유사활성능도 13.06%의 활성을 나타내었다. 또한 전자공여능에서도 뿌리 에탄올 추출물이 98.58%로 천연항산화제인 ascorbic acid보다 높은 활성을 보였다. 이상의 결과 우산나물 뿌리의 에탄올 추출물의 폴리페놀 함량이 가장 높았고, tyrosinase 저해, 아질산염 소거, SOD 유사활성 및 전자공여능이 가장 우수하였다. 우산나물 뿌리의 물 추출물은 에탄올 추출물보다는 활성이 낮았으나 우산나물 지상부 추출물보다 높게 분석되었으며, xanthine oxidase 저해율이 가장 높았다. 본 실험결과 우산나물은 우수한 항산화 활성을 지닌 기능성식품 소재임을 확인할 수 있었으며, 식용으로 사용하고 있는 어린순 이외에 뿌리에도 다량의 폴리페놀을 함유하며, 우수한 생리활성 효과를 나타내므로 이를 항산화 활성을 지닌 기능성 건강식품 등의 재료로 활용할 수 있을 것으로 생각된다.

A chemical examination of the aerial parts of Euphorbia pekinensis $R_{UPRECHT}$. (Euphorbiaceae) has led to the isolation of seven hydrolyzable tannins and ten fl avonoid glycosides. The former ones have been identified as gallic acid, methylgallate, 3-O-galloyl shikimic acid, 1,3,4,6-tetra-O-galloyl-${\beta}-_D$-glucose, 1,2,3,4,6-penta-O-galloyl-${\beta}-_D$-glucose, corilagin, geraniin and the latter ones as isoquercitrin, quercitrin, astragalin, afzelin, prunin, rutin, kaempferol-3-O-rutinoside, quercetin-3-O-(2"-O-galloyl)-${\beta}-_D$-glucoside and quercetin-3-O-(2"-O-galloyl)-${\alpha}-_L$-rhamnoside on the basis of chemical and spectroscopic evidence.

The chromatographic separation of the MeOH extract of the aerial parts from Aster hispidus (Compositae) led to the isolation of eight compounds. Their structures were established by spectroscopic methods to be ${\beta}-amyrin$ (1), oleanolic acid (2), (2R)-1, 2-O-(9Z, 12Z, $15Z-dioctadecatrienoyl)-3-O-{\beta}-D-galactopyranosyl\;glycerol$ (3), trans-phytol (4), 9, 12, 15-octadecatrienoic acid (5), kaempferol (6), 3,5-dicaffeoyl quinic acid (7), 3,4-dicaffeoyl quinic acid (8) and kaempferol-3-O-rutinoside (9). Compounds 1, $3{\sim}6$ and 9 showed non-specific moderate cytotoxicity against five human tumor cell lines $(5.44{\sim}23.51\;{\mu}g/ml)$. The other compounds were of marginal activity against tested five human cancer cell lines $(9.05{\sim}>30.0\;{\mu}g/ml)$.

In a bioassay-guided search for acetylcholinesterase inhibitors from Korean natural resources, four isoquinoline alkaloids, corynoxidine (1), protopine (2), palmatine (3), and berberine (4) have been isolated from the methanolic extract of the aerial parts of Corydalis speciosa. Structures of these compounds were elucidated on the basis of spectroscopic techniques. These compounds inhibited acetylcholinesterase activity in a dose-dependent manner, and the $IC_50$ values of compounds 1-4 were 89.0, 16.1, 5.8, and 3.3 $\mu$ M, respectively.

Bacopa monnieri is being used in the traditional system of medicine for a variety of ailments. In the present study, the ethanolic extract of Bacopa monnieri aerial parts has been studied for its wound healing activity using various models in rats. Significant increase in wound contraction and skin breaking strength were observed in the excision and incision wound models respectively. There was also significant increase in hydroxyproline content, DNA content, superoxide dismutase activity, catalase activity, glutathione level and decrease in the level of thiobarbituric acid reactive substances in the $12^{th}$ day post wounding tissue of experimental rats in the ethanol extract treated groups with respect to the control group. The effect of the extract was found to be comparable with the standard drug nitrofurazone. From the results it may be concluded that the plant Bacopa monnieri is endowed with significant wound healing activity, thereby justifying its use in the traditional medicine. Saponins may be responsible for the observed wound healing activity.
