The methanol extracts of 25 leguminous seeds in vitro were evaluated for inhibitory activities against lens aldose reductase of Sprague Dawley male rats. The responses varied with both leguminous seed and concentration used. At the concentration of 0.1 mg/mL, the methanol extracts from Amphicaraea edgeworthii, Canavalia lineata, Gylcine max var. solitae, Glycine max var. yagkong, Glycine max var. hooktae, Glycine max var. bangkong, Glycine max var. geumdu, Glycine max var. chungtae, Glycine max var. mejukong, Glycine soja, Phaseolus radiatus var. geodu, Vicia tetrasperma, Vigna angulasis, and Vigna sinensis inhibited enzyme activity by greatertha 60%. In following study, at the concentration of 0.01 mg/mL, the extracts of C. lineata and V. tetraspermahad relatively strong inhibitory activity against aldose reductase. Because of their potent inhibitory activities, the activity of each solvent fraction from C. lineata and V. tetrasperma was determined, and the potent activity was showed from chloroform and hexane fractions, respectively. {TEX}$IC_{50}${/TEX} values of C. lineata and V. tetrasperma were 0.004 and 0.006 mg/mL, respectively. As a naturally occurring therapeutic agent, leguminous seeds described could be useful for developing new agents of antidiabetic complications.

The composition of lipid class and fatty acid of free lipids(FL) and bound lipids(BL at low temperature and BL at high temperature) from Mungbean (Phaseolus radiatus, L) was investigated with the chromatographic procedures. The contents of neutral lipid (NL), glycol lipids(GL) and phospholipids(PL) in FL were 89.1%, 7.1%, and 3.7%, on the other hand those of BL were $49{\sim}56%,\;28{\sim}29%\;and\;15{\sim}21%$, respectively. The major components of NL fraction were triglycerides, 1,2-diglycerides and esterified sterol in the lipids of FL and BL. Esteryl steryl glycosides and monogalactosyl diglycerides were observed as major GL components of FI and BL. Of the PL in FL and BL, phosphatidyl ethanolamine, diphosphatidyl glycerides and phosphatidyl choline were the major components. The predominent fatty acids of NL, GL and PL were linoleic, palmitic and linolenic acids. There are a little difference between the compositions of BL at low and high temperature extraction.

The compositions of lipid class and fatty acid of free lipids as non-starch lipid and bound lipids(extraction either at low or high temperature) as starch-lipid extracted from starch in mung bean(phaseolus radiatus L) was investigated. The contents of neutral lipids glycolipids and phospholipids in free lipids were 98.2% 1.7% and 0.1%, whereas those found in bound lipids were 84.3-85.7% 10.5-11.0%, and 5.2-3.3% respectively The major components of neutral lipid fraction in the bound lipids were triglyceride and esterified sterol and those were composed of 0% of total neutral lipids. Monogalactosyl idiglyceride and esteryl steryl glycoside were observed as main glycolipids components in both free and bound lipids. Among the phospholipids in the bound lipids phosphatidylinositol phosphatidyl serine and phosphati-dyl ethanolamine were identified an major constituents. The free lipids contained palmitic(50.2%) stearic(20.6%) oleic(8.5%) and behenic(7.4%) acids and bound lipids had more palmi-tic and linoleic acids but less stearic acid compared to thosed in the free lipids.

Safflower Yangengs were prepared with composite dried powder of small red bean(Phaseolus radiatus L.) containing various ratios of safflower(Carthamus tinctorius L.) seed powder sifted through 20, 35, 45 and 60 mesh size and kinds of mixed water, their cooking characteristics were evaluated. Water content and water activity of cooked products were increased as the content and sieve mesh number of safflower seed powder increasing from 5%, 20 mesh to 20%, 60mesh, respectively. Color values of yangeng were increased in green tea extract mixed water. Rheological properties of yangengs were measured by compression test with texture analyzer, as results, hardness and fracturability increased that were shown in high content and high mesh number sifted safflower seed powder, but adhesiveness and springiness decreased, respectively. From the sensory evaluation test for yangeng, sensory scores were good scores in more mesh number sifted powder addition, especially overall acceptance, texture and fracturability. The 45mesh and 15% powder added yangeng was noted as having high sensory scores and preferable acceptability in sensory evaluation.

The objective of this study was to optimize the mixing ratio of mixed bean protein concentrate (MBPC) and to improve the quality of sausage analogues. Soybean (Glycine max MERR), mung bean (Phaseolus radiatus L.), red bean [Vigna angularis (Wild.)], and pea (Pisum sativum L.) were mixed and processed to produce a MBPC, which was used to make a sausage analogue. The protein, moisture, and carbohydrate content were significantly (p<0.05) different among the samples. A significant (p<0.05) improvement was observed in textural properties (hardness, gumminess, and chewiness), cooking loss, frying loss, and emulsion stability of the sausage analogue. This study suggested the possibility of attaining high-quality sausage analogues and partial sausage analogues using MBPC, which could serve as a potential ingredient in meat analogues.

The proximate compositions, quality and physicochemical characteristics of mung-bean cultivars cultivated in the north-central region of South Korea with different seeding periods were evaluated. A significant difference was noted in the proximate compositions and chromaticity of mung-beans according to cultivars and different seeding periods. Crude ash and protein content decreased with the delay in seeding period and a slight increase in carbohydrate content was observed. Redness of the other five cultivars increased with the delay in seeding period except for the cultivar Jangan, while the yellowness decreased in cultivars Geumsung and Jangan. Water binding capacity of the $1^{st}$, $2^{nd}$ and $3^{rd}$ seeding on the cultivar Eoul was 115.15, 99.76 and 96.31%, respectively, and a decrease in the binding capacity was observed with the delay in seeding periods. Water solubility index and swelling power were significantly different among cultivars. Total polyphenol content of $1^{st}$ and $2^{nd}$ seeding on the cultivar Jangan was 8.59 and 8.57 mg GAE/g, respectively, and a decrease was observed with the delay in seeding periods except for the cultivar Sohyeon. Total flavonoid content of $1^{st}$ seeding on the cultivar Jangan was 5.25 mg CE/g, which decreased with the delay in seeding periods. DPPH radical scavenging activity of $1^{st}$ seeding on the cultivars Geumsung and Kyungseon was 2.44 and 2.32 mg TE/g, respectively, which decreased with the delay in seeding periods. The BTS radical scavenging activity of $1^{st}$ seeding on the cultivar Jangan was 6.98 mg TE/g. In the present study, the variations in phenol content and radical scavenging activity were observed to be dependent on the cultivars and seeding periods.
