To evaluate the effect of Ulmus devidiana powder, muffins with Ulmus devidiana powder were made after supplementation with Ulmus devidiana powder(0, 5, 10 and 15%(all w/w)). Proximate composition of Ulmus devidiana powder was 7.49% moisture, 2.33% crude protein, 0.84% crude lipid, 66.74% carbohydrate, 14.09% crude fiber and 8.5% crude ash. The sample with 15% of Ulmus devidiana powder showed significantly lower volume compared to other groups. The symmetry of the sample with 5% of Ulmus devidiana powder was significantly lower than that of control group. No significant uniformity changes were observed. The height and baking loss rate of muffins with 15% Ulmus devidiana powder showed lower than that of other groups. But the weight of muffins with 15% Ulmus devidiana powder showed heavier than that of other groups. In color, L value and b value of muffins were decreased as the increase of the Ulmus devidiana powder. a value of muffins with Ulmus devidiana powder were higher than that of the control group. Hardness, gumminess and chewiness of groups with Ulmus devidiana powder were increased significantly as the increase of the amount of Ulmus devidiana powder. No changes of springness and cohesiveness were observed. Color, hardness, root odor and bitter taste intensity increased significantly with the increased addition of Ulmus devidiana powder. Acceptance of appearance, taste and overall acceptability of groups with 10% of Ulmus devidiana powder were significantly higher than that of the control group. As a result, 10% of Ulmus devidiana powder will be ideal to make muffins.

This study was designed to investigate the effective ratio of bread with Ulmus devidiana. The bread with various contents(0, 10, 20, 30%) of Ulmus devidiana were measured by volume, color difference, texture and sensory evaluation. The results were as follows: The dough yield tended to increase by adding Ulmus devidiana extract but those were not significant difference. The loaf volume index increased by adding Ulmus devidiana extract. The texture(hardness, cohesiveness, springiness, gumminess, chewiness) of bread increased by the addition Ulmus devidiana extract. Color L, a and b value were not significant difference. In sensory evaluation, bread with 10% Ulmus devidiana extract was evaluated as the best in taste, texture, flavor and overall acceptability.

To measure antioxidative activities, the various extracts from Ulmus devidiana were examined in oil emulsion. Water, ethanol, methanol and butanol were used as extract solutions. The activity oxygen species ($H_2O_2,-OH,\;KO_2$) bound the extracts for antioxidative activities were excellent. The extracts bound $Fe^{2+}$ ion and $Cu^{2+}$ ion showed effective antioxidative activities and strong chelating effects. The concentration of $Fe^{2+}$ ion and total ion in ethanol and methanol extracts from Ulmus devidiana root parts (Chinese) were higher than those of the other products. The highest superoxide dismutase-like activities showed butanol extracts from Ulmus devidiana root parts (Chinese) and water extracts from Ulmus devidiana bark parts (Korean). Electron donating abilities and nitric scavenging abilities of ethanol, methanol and butanol extracts were higher than those of water extracts. The nitrite scavenging abilities also reached the maximum at pH 1.2 and the minium at pH 6.0.

Objectives : This studies were carried out to evaluate the effects on anti-oxidation activities in different parts as trunk bark and root bark of Ulmus devidiana Planchon. var. japonica Nakai and Hemipteleae davidii (Hance) Planchon. Methods : For evaluation of antioxidative effects, scavenging activity on superoxide anion radical and DPPH radical were measured. Also, inhibitory activity on LDL oxidation and linoleic acid peroxidation were measured in each samples. In the in vivo test, inhibitory activity on TBARS production, GSH contents in rat liver were measured. SOD, Catalase, GSH-px and ALDH activity were analysed in ethanol extracts of Ulmi Radicis Cortex. Result : 1. Scavenging activity on superoxide anion radical was higher in water extract than in ethanol extract even in low concentration of 50ppm as over 90%. 2. There was no difference between water extract and ethanol extract in the scavenging activity on DPPH radical but, Ulmi Raclicis Cortex and Ulmi Trunci Cortex showed high effect even in low concentration of 10ppm. 3. GSH reduction was prevented and antioxidative activity such as Mn-SOD, GSH-px in the rat liver recovered in the treatment of ethanol extracts of Ulmi Radicis Cortex. Conclusion : Ulmi Radicis Cortex recorded as Ulmi Trunci Cortex in official regulation book. But, it was known that Ulmi Radicis Cortex was more effective than Ulmi Trunci Cortex in most physical activities.
