  • In order to develop new materials for the functional food, the components of safflower(Carthamus tinctorius L.) sprout was studied. Chemical composition, minerals, amino acids, and fatty acids of the leaf and the stem parts of 2 weeks grown safflower sprout were analyzed. The chemical composition of safflower spout was 12.7% (w/w) moisture, 28.5% crude protein, 10.1% crude fat, and 5.3% crude ash. Mineral contents of the leaf part were P 49%, K 22%, Mg 15%, Ca 10% whereas these of the stem part were K 51%, P 27%, S 10%, Ca 7%, Mg 4%. Other mineral contents were less than 2% in both parts. Especially, Pt was 0.18 ppb and 0.17 ppb in the leaf and the stem parts, respectively. The composition of the amino acid were approximately as follow, the major amino acid in the leaf and the stem were aspartic acid and glutamic acid, the contents of these were 10.7mg/g, 10mg/g in the leaf, 11.3 mg/g, 8.4 mg/g in the stem, respectively. The major fatty acids in the leaf and the stem parts were linoleic acid and $\alpha$-linolenic acid. The linoleic acid (C18:2) in the leaf and the stem parts were 67% (w/w) and 47% whereas the $\alpha$-linolenic acid. The linoleic acid (C18:2) in those parts were 14% (w/w) and 11%, respectively. On the basis of chemical analysis, the safflower sprout showed to have relatively high contents of crude protein and crude fat, minerals including small amount of Pt, polyunsaturated fatty acid as linoleic acid and $\alpha$ -linolenic acid. These results suggested that safflower sprout was found to be a useful material of natural health food for the functional food development.

  • This study was conducted to obtain basic information on mainstem, branch and leaf characteristics related to canopy for development of high yielding cultivar using 70 Korean soybean cultivars developed from 1913 to 2000. Variations of canopy width, branch length, and canopy width/length ratio were higher compared to other characteristics among 12 mainstem and branch characters. Variations of petiole angle, leaflet width/length ratio and compound leaf dry weight were higher than other characteristics among eight leaf characters related to plant canopy. Three classifications of soybean cultivars were used based on usage: I)soy sauce and tofu, II)bean sprout, and III)cooking with rice. Canopy width/length ratio was higher in group III, cooking with rice than group I, soy sauce and tofu, and group II, bean sprout, and there was no difference between the two, group I and group II. The total branch length/main stem height ratio was higher in group II, bean sprout and group III, cooking with rice than group I, soy sauce and tofu. Mainstem and branch characteristics related to plant canopy were classified into four groups by ratio of canopy width/length and total branch length/main stem length, respectively. Soybean cultivars with narrow canopy and high dependence of mainstem were Danweonkong, Keumkangkong, Shelby, and Shinpaldalkong. Soybean cultivars with broad canopy and high dependence of mainstem were Kanglim, Keumkangdaelip, and Jinyulkong, and a cultivar with broad canopy and high dependence of branch were Geomjeongkong 2. Leaflet length/width ratio was lowest in cooking with rice and there was no difference between soy sauce and tofu and bean sprout. Compound leaf area was largest in cooking with rice and smallest in bean sprout. Leaf petiole length was short in bean sprout and there was no difference between soy sauce and tofu and bean sprout. Leaf petiole angle was highest in cooking with rice and lowest in bean sprout. Leaf type was classified into four groups based on leaflet width/length ratio and compound leaf area, respectivly. Buseok and Taekwangkong had an oval leaflet and largest area of compound leaf. Eunhakong and Sohokong had extreme narrow leaflet and smallest area of compound leaf. Leaf petiole type was classified into three and four groups based on leaf petiole length and angle, respectively. A soybean cultivar with the shortest petiole length and smallest petiole angle was Eunhakong and cultivars with short petiole length and large petiole angle were Alchankong, Muhankong, and Pureunkong. A soybean cultivar with long petiole length and small petiole angle was Sinpaldalkong 2. Among a total of 70 Korean soybean cultivars, Eunhakong had an extreme narrow type in leaf, smallest compound leaf area, shortest petiole length, and smallest petiole angle of compound leaf.

  • This study was performed to investigate the possible effects of some plants protecting intact rat liver damaged by $CCl_4$. The extract of mugwort (Artemsiae capillaris), soybean sprout and pine leaf (Pinus strobus) inhibited markedly the in vitro activities of rat liver fatty acid synthase, whereas those of shiitake (Lentinus ododes), Houttuynia cortata, Acanthopanacis cortex and buckwheat leaves had less effects. Treatment with the water extract of pine leaf and soybean sprout caused a marked decrease in the $CCl_4$-induced toxicity in rat liver, judged from their effects on the levels of glutamic oxaloacetic transaminase (GOT) and glutamate pyruvic transaminase(GPT) in the serum. The extract of mugwort and soybean sprout reduced markedly the content of liver microsomal peroxides induced by $CCl_4$ treatment and serum TBA values, respectively. The extract of soybean sprout decreased efficiently the content of liver triglyceride elevated by $CCl_4$ treatment. Nevertheless, the extracts did not exert the supression of hepaticmegaly induced by $CCl_4$. The results suggest that soybean sprout and pine leaf may be potential sources improved the biochemical parameters like as peroxidation value or serum GOT and GPT, although these extracts had minimal effects in the increase of liver size induced by carbon tetrachloride.

  • This paper presents a nature-inspired wideband sprout-leaf shaped antenna with end-fire radiation pattern. A sprout-leaf shape angled-radiator was designed for wide beamwidth radiation patterns for motion detection sensors. An extended and truncated ground plane was used as a reflector for end-fire radiation patterns. To feed the balanced radiator, a broadband microstrip (MS) to coplanar stripline (CPS) balun was utilized with excellent amplitude and phase balance. The proposed antenna demonstrates wide frequency bandwidth from 8.5 to 14.5 GHz with wide beamwidth and the radiation efficiency of 90%. The measured gain is from 4 to 5 dBi and front-to-back ratio was 10 to 20 dB. It has been shown that the proposed antenna can be used for imaging sensors, phased array systems, and radars that require a wide bandwidth and a directional radiation pattern.

  • Purpose: This study was carried out to predict the growth period and fresh weight of sprouts grown in a cultivator designed to grow sprouts under optimal conditions. Methods: The temperature, light intensity, and amount of irrigation were controlled, and images of seed sprouts were acquired to predict the days of growth and weight from pixel counts of leaf area. Broccoli, clover, and radish sprouts were selected, and each sprout was cultivated in a 90-mm-diameter Petri dish under the same cultivating conditions. An image of each sprout was taken every 24 hours from the 4th day, and the whole cultivating period was 6 days, including 3 days in the dark. Images were processed by histogram inspection, binary images, image erosion, image dilation, and the overlay image process. The RGB range and ratio of leaves were adjusted to calculate the pixel counts for leaf area. Results: The correlation coefficients between the pixel count of leaf area and the growth period of sprouts were 0.91, 0.98, and 0.97 for broccoli, clover, and radish, respectively. Further, the correlation coefficients between the pixel count of leaf area and fresh weight were 0.90 for broccoli, 0.87 for clover, and 0.95 for radish. Conclusions: On the basis of these results, we suggest that the simple image acquisition system and processing algorithm can feasibly estimate the growth period and fresh weight of seed sprouts.

  • In this study, we investigated the potential of 70% ethanol extracts from wild edible plants (Pueraria lobata sprout, Rosa multiflora sprout, Artemisia princeps leaf, Diospyros kaki leaf, Morus alba leaf, Robinia pseudoacacia flower, Inula britannica var. japonica flower), as natural antioxidants. The antioxidant contents and activities of extracts were examined using various methods. The measurements of total polyphenol content revealed that Rosa multiflora sprout extract had the highest value and total flavonoid content showed that Diospyros kaki leaf extract had the highest value. Antioxidant activities were the highest in Rosa multiflora sprout for DPPH (IC50 232.52 ㎍/mL), ABTS+ (IC50 470.10 ㎍/mL), superoxide- (IC50 431.88 ㎍/mL), nitrite (IC50 363.38 ㎍/mL) scavenging activity, and reducing power (2.47 O.D.). These results suggest that the ethanolic extract of Rosa multiflora sprout is a potential source of natural antioxidants.

  • The purpose of this study was to determine the content of polyphenols and flavonoids, vitamin C, and antioxidant activity for the extract from the Deodeok sprout. To accomplish this, the Deodeok sprout whole (CLS-W), above ground part (leaf, stem, CLS-L), and root (CLS-R) were individually extracted using 70% ethanol. The highest levels of total polyphenols and total flavonoids were observed in the Deodeok sprout extract CLS-L2. Similarly, antioxidant activities resulting in radical scavenging activities increased significantly in the extract of CLS-L2. In conclusion, these results indicate that Deodeok sprouts can be used as a viable, new natural antioxidant source.

  • Lateral roots of soybean sprouts should deeply affect their quality and marketability. The study was done to compare the effects of ocher, chitosan, corn kennel, tea (Thea sinensis L.) and hard rubber tree (Eucommia ulmoides Oliver) leaf extracts on lateral root formation, growth and morphological characters of the sprouts. Seeds of three cultivars, Pungsannamulkong, Sowonkong and Junjery, were imbibed for 5 hours into their 10% solutions and cultured for 6 days. The cultured sprouts were classified into 4 categories to calculate their composition rates on the base of hypocotyl lengths;>7 cm (A), 4 to 7 cm (B), < 4 cm (C) and not germinated (D), and their morphological characters, fresh and dry weights were measured. Composition rate of A was the lowest in Junjery of the three cultivars, while that of C showed reverse result compared to A. This results was the most distinct in hard rubber tree leaf extracts (HRTLE) of the five treatments. In HRTLE treatment, lateral root formation rate were formed in almost of Sowonkong although reduced in order of Pungsannamulkong and Junjery. However, there was no significant difference between the other treatments. Lateral roots per sprout were the lowest in HRTLE treatment of the 5 treatments. In all treatments except the chitosan treatment, the roots were most formed in Sowonkong but least in Junjery. Sprout length adding hypocotyl and root was the shortest in Junjery compared to the other two cultivars. and was the longest in tea leaf extract treatment but the shortest in HRTLE treatment. The result in total fresh weight of sprouts was similar to that of the sprout length.
