The contents of dietary fiber and its physical properties of vegetables were determined. The samples selected in this study were soybean sprouts (Glycine max MERILL sprouts) butterber (Petasites japonicus MIQ), taro stem(Colcasia antiquorum SCHOTT stem), bracken (Pteridium aquilinum KUHN)and dried Korean cabbage leaves(Brassica compestris L.leaves). The contents of dietary fiber were 20.96~50.62% of neutral detergent figer, 10.60-38.19% of acid detergent fiber, 1.74-10.88% of lignin, 5.79~33.29% of hemicellulose and 5.79-33.29% of cellulose. Butterber had the highest dietary fiber content. Mean waterholding capacity of samples was 5.65-12.26g.water/g.acetone dried powder and butterber and dried Korean cabbage leaves had higher water holding capacity value than the others. Densities were 140-250mg/ml of direct density and 385-417 mg/ml of bulk density.

The purposes of this study are to calculate the green and dried weight using wood discs, to figure out weight change on air drying times, and to develop the model of wood disc weight change for Larix kaempferi, Pinus koraiensis, and Pinus densiflora. The variables affecting the weight change were investigated, and the pattern of weight change over time was figured out through linear models. When comparing the stem green weight calculated using wood discs in this study with the weight table of Korea Forest Service, the weight was not significantly different for L. kaempferi and P. koraiensis. On the other hand, in comparison of stem dried weight, the weight was significantly different in all of three species. In addition, various measurement factors were examined to figure out the relationship with weight change, and air drying times and disc diameter were found as significant independent variables. Finally, two linear models were developed to estimate air drying times of three species, fit statistics were significant for practical use.

The objective was to verify biological activities of fruit and stem of prickly pear(Opuntia ficus indica L. var, saboten Makino). We have determined inhibitory activities on enzymes, such as dopamine ${\beta}$-hydroxylase(DBH), monoamme oxidase A and B(MAO-A, B), and antioxidant activity, in vitro. We purchased dried stem powder and lyophilized fruit powder of prickly pear from CheJu Island, and prepared the extracts with 80% of methanol. The fruit extract showed stronger inhibitory effects on MAO-A and -B and antioxidant activity compared. to the stem extract, on fractionation with hexane, ethyl acetate, butanol and water. Both the stem and the fruit extracts with ethyl acetate showed stronger enzyme inhibitory and antioxidant activities than other extracts. Now we are isolating active principles from both ethyl acetate extracts.

Stem firmness and flowering response of cut lily as influenced by medium composition (Control: Upland soil, Pt: Peatmoss, Pe: Perlite, Ve: Vermiculite, Rrh: Rotted rice-hull, RPt: Russian Peatmoss) were studied. For 'Casa Blanca', plant height and length of flower stalk increased when bulbs were planted in Pt:Rrh:Ve(1:1:1, v/v), and dried leaves of lower part plants decreased by RPt:Pe:Rrh(1:1:1, v/v). In case of 'Marco Polo' plant height and length of flower stalk increased with Pt:Rrh(1:1, v/v) as compared to other treatment, number of leaves and dried leaves increased when bulbs were planted in RPt:Pe:Rrh(1:1:1, v/v) as compared to control. Flowering of 'Casa Blanca' was promoted in Pt:Pe:Ve(1:1:1, v/v) and 'Marco Polo' was accelerated in Pt:Rrh:Ve(1:1:1, v/v). Flower length of 'Casa Blanca' was increased by RPt:Pe:Rrh(1 :1 :1, v/v) as compared with control and 'Marco Polo' was increased when bulbs planted to Pt:Rrh(1 :1, v/v). Flower-bud blasting of two cultivars was increased with Pt as compared with other treatment. Stem firmness of 'Casa Blanca' was increased by Pt:Pe:Ve (1:1 :1, v/v), and especially, stem firmness of upper part plants was increased by Pt:Rrh(1 :1, v/v) in 'Marco Polo' as compared to control plants. but generally, stem firmness of 'Casa Blanca' was not influenced with all cultural media as compared to control.

It was revealed that magnolol and honokiol isolated from the stem bark of Magnolia obovata, had potent antibacterial activity against Bacillus anthracis. A quantitative analytical method of magnolol and honokiol by HPLC has been established, and the amounts of the two components in the dried stem bark of M. obovata were 1, 94% and 0.44%, respectively.

Stem rot of cacti was found at major cultivating areas including Koyang, Ansung and Eumsung of Korea in 2000. Bipolaris cactivora was consistently isolated from the lesions. The disease occurred on different species of cactus including Cereus peruvianus, C. neopithahaja f. monstruo년, C. tetragonus, Chamaeceresu silestrii, Ch. silvestrii, f. variegata, Gymnocalcium mihanovichii var. friedrichii. G. denudatum var. pentacantha, Hylocereus trigonus and Isolatocereus dumortier. Major symptoms on the cactus species except H. trigohus were almost identical. A rapid rot of the upper portion of the catus stem appeared, and became blackened and somewhat dry. On H. trigonus, the symptom was initially light yellow, water-soaked lesion, turned into light brown and dried to death. According to pathogenicity test, 10 out of 16 cactus species and varieties tested produced identical symptoms as found in the field. However, the fungi did not show pathogenicity to Notocactus scopa, Echinocactus grusonii, Eriocactus leninghausii, Lobivia nealeana, Mammillaria elongata var. intertexta.

An on-line real time grading and sorting system for dried oak mushrooms was developed for on-site application. Quality grades of the mushrooms were determined according to an industrial specification. Three dimensional visual quality features were used for the grading. A progressive color computer vision system with white LED illumination was implemented to develop an algorithm to extract external quality patterns of the dried oak mushrooms. Cap (top) and gil (stem) surface images were acquired sequentially and side image was obtained using mirror. Algorithms for extracting size, roundness, pattern and color of the cap, thickness, color of the gil and amount of rolled edge of the dried mushroom were developed. Utilizing those quality factors normal and abnormal ones were classified and normal mushrooms were further classified into 30 different grades. The sorting device was developed using microprocessor controlled electro-pneumatic system with stainless buckets. Grading accuracy was around 97% and processing time was 0.4 s in average.

This study was conducted to survey some characteristics in growth of perilla by fertilization level organic matter. Corn stalk, acorn and chestnut were used as organic fertilizer in this study. In the height of perilla, chestnut fertilizer with 880kg/10a that R2 is 0.9996 showed the height level, and followed by acorn and corn stalk in order. Number of the harvested leaves was the highest in acorn among the three organic fertilizer by chestnut and corn stalk in order. However, number of the harvested leaves continuously was the highest in chestnut. Weight of a leaf was more effective at three kinds of organic fertilizer than control. There were no difference in the rate of dried leaf weight according to kinds of organic fertilizer. On the other hand, the rate of dried leaf weight by growth period was different. It was found that the rate of dried leaf in 30days or 110days. Diameter of perilla stem at 30cm above the ground according to kinds and fertilizer level of organic fertilizer was surveyed. However, the difference was not detected in this study.

The effects of the dried stem powder of Opuntia ficus-indica var. saboten (OF-s) were investigated on gastric lesion and ulcer models in rats. It showed significant inhibition in HCl·ethanolinduced gastric lesion at the doses of 200 and 600 mg/kg p.o. and in HCl·aspirin-induced gastric lesion at 600 mg/kg p.o. OF-s also showed significant inhibition in indomethacin-induced gastric lesion at the doses of 200 and 600 mg/kg, p.o. However, it did not affect both the aspirin-induced and Shay ulcers in rats. It also did not affect gastric juice secretion, acid output and pH. These data indicate that OF-s only possesses pronounced inhibitory action on gastric lesion without antiulcer activity in rats.

Albizzia julibrissin Durazz (Leguminosae) is a small domed to flat-topped, spreading tree with smooth. gray-brown bark and doubly pinnate leaves. It grows abundantly in Korea. The dried stem bark of A. julibrissin is used as a tonic in China, Japan and Korea. From the stem bark of A. ju/ibrissin, a new unsaturated hydroxy fatty acid was isolated and characterized as 4-hydroxy-dodec-2E-enedioic acid on the basis of several data including 2D-NMR. (omitted)
