This study was conducted to investigate the effect on the growth of soybean sprouts under control of various water supply, and to develop the culture methods for the production of clean soybean sprouts. The yield and characteristics of soybean sprouts was more affected by the watering interval(hours) than the quantity of supplied water (minute). However, the hypocotyl/whole length ratio of soybean sprouts was more affected by the quantity of supplied water than the yield, whole length and hypocotyl length of soybean sprouts. The hypocotyl/whole length ratio of soybean sprouts was increased about 55∼63% under the control of 2hrs-4min water supply, and about 57% under the 4hrs-4min water supply, respectively. The α-naphthylamin oxidation activity was tested on the soybean sprouts under the watering interval and quantity of water supply. The α-naphthylamin oxidation activity was decreased after 7 days of germination, and the activity of cotyledon removed soybean sprouts was lower than that o� intact soybean sprouts. The α-naphthylamin oxidation activity had the signficant quadratic regression with the yield, whole length, hypocotyl length, and hypacotyl/whole length ratio. Hardness and chewiness of the boiled soybean sprouts was more improved by 2hrs-4min and 4hrs-4min water supply than those of others water supply controls.

The objective of this study was to examine the physicochemical characteristics of the soybean sprouts according to culture period. The texture characteristics and extensibility of hypocotyl of cooked soybean sprout during culture were increased continuously. Also the acid detergent fiber(ADF) contents of soybean sprout was increased during culture periods. The cellulose contents increased from 8.52% at 3rd day to 17. 16% at 8th day on dry basis. Vitamin C and total amino acid content were the highest at the 5th day. In sensory evaluation, preference score of 6th day was the highest during culture period. The more culture period is short, the more preference score is high.

천연물로부터 새로운 항산화물질을 구명하기 위하여 국내에서 생산된 약용작물 38종을 수집하여 항산화 활성물질을 탐색한 결과 가시오갈피, 구절초, 건강, 목단, 시호, 산수유, 삼백초, 산사, 유근피, 작약, 천궁, 홍화씨, 및 황금등 13종이 항산화 활성이 높은 생약재로 선발되었다. 선발된 13종의 생약재중 홍화씨에 대한 활성물질을 추적, 분리하여 NMR로 물질구조를 동정한 결과 N-feruloylserotonin이 항산화 물질이라는 것을 처음 밝혀냈다. DPPH radical소거 활성에 의한 기존 항산화제인 α-tocopherol, BHA 및 BHT를 N-feruloylserotonin과 항산화력를 비교한 결과 N-feruloylserotonin이 6.6μg/ml로 활성이 가장 높은 것으로 밝혀졌다. On the purpose of development of antioxidative compounds from natural sources, 38 plants known to have antioxidant activity have been examined concerning DPPH radical scavenging activity. Among 13 plants exhibiting the activity, the seed of Carthamus tinctorius L, was selected as resources to search for active compounds due to rareness of study. The seed of the plant has been used as edible oil or preventive and remedial drugs for osteoporosis, arthritis. To reveal the principal component manifesting the antioxidant activity, the MeOH extracts was successively solvent-fractionated with EtOAc, n-BuOH and water. In order to isolate active component from the EtOAc fractions, application of silica gel column chromatographies and activity tests were repeated for a active component to be isolated. Its chmical structure was determined to be N-feruloylserotonin, a conjugated serotonin compound, by the interpretation of spectral data, NMR. MS and the adaptation of chemical reactions.
