The purpose of this study was to investigate the physicochemical and sensory characteristics of A. scaber noodle added with A. scaber extract solution or powder. The weight of cooked noodle and noodle added with A. scaber extract solution was higher than those of the non-added noodle (control) and dried A. scaber powder added noodle. As the amount of A. scaber extract solution or powder was increased, the water absorption rate of noodle was decreased. As the amount of A. scaber solution or powder was increased, the 'L' values of noodles were decreased. Since the 'a' values of all noodles were negative and the 'b' values of all noodles were positive, the color of all noodles were determined to be yellow green. The pH of noodles were 5 to 6 in control noodles and noodles with A. scaber powder. The pH of noodle added A. scaber extract solution was lower than those of others. As amount of A. scaber extract solution or powder was increased, the elasticity of all noodles was decreased. The chewiness of noodles was the highest in noodle added A. scaber extract powder. The quality of noodle added A. scaber extract solution was the excellent among the all other noodles. This result showed that, the quality characteristics and palatability of noodle added A. scaber extract solution or powder was higher than those of control noodle.

The purpose of this study was to investigate the sensory and physicochemical attributes of Cham-chwi dduk with various amounts of Cham-chwi(Aster scaber) and salt. Cham-chwi dduk was made by steaming glutinous rice flour with Cham-chwi powder for 15 min. Cham-chwi powder was added 1, 3, 5% of glutinous rice flour weight and salt was added 0.5, 1.0 1.5%. According to the sensory evaluation, bitterness and Cham-chwi flavor increased as the amount of Cham-chwi increased and saltiness increased as the amount of salt increased(p<0.05). In the textural profiles, chewiness, adhesiveness, hardness and gumminess were highest when 3% Cham-chwi was added. The moisture content of Cham-chwi dduk was increased as the amount of Cham-chwi was increased and the amount of salt was decreased. The more amount of added Cham-chwi increase, the more green color was strong and yellow color was weak. These results were used to determine the optimum conditions of adding levels of Cham-chwi and salt. Conditions were standardized with minimum range of firmness when expected value of Cham-chwi flavor was more than six and expected value of bitterness was less five. The optimum conditions of Cham-chwi dduk was established as the 3.1% Cham-chwi and 0.6% salt.

The purpose of this study was to evaluate the functionality of ethanol extract of Aster scaber by analyzing anti-oxidant components and anti-oxidant activities, which was grown in wild and culture field. The yields of Aster scaber ethanol extracts were high after blanching treatment. The polyphenol content of dried Aster scaber grown in wild was 35.59 mg/g, which was higher than that of Aster scaber grown in culture field. The electron donating ability in all Aster scaber extracts were increased with increase in extract concentration, and the electron donating ability was the highest in extracts of the dried Aster scaber after blanching. The SOD-like activity of Aster scaber was the highest in its extract grown in wild field. In addition, the SOD-like activities of extracts of the dired Aster scaber after blanching were highest among the extracts of cultivated Aster scaber. The nitrite scavenging ability of extracts was increased at pH 1.2, and those was the highest in wild fresh Aster scaber. The inhibition effects on xanthine oxidase and tyrosinase were increased with increase in extract concentration, and the inhibition effects of extracts of Aster scaber in wild field were higher than those grown in culture field. Therefore, the consumption of Aster scaber would provide beneficiary effects due to its antioxidant activities and prevention of aging. The development of various processed food using Aster scaber will promote the consumption and its values.

The present study was conducted to investigate effect of powdered herb of Aster scaber Thunb. (chamchwi) on antioxidant system in ethanol-administrated rats. Four week-old Sprague Dawley male rats which had initial body weights of 97.10$\pm$4.50 g were randomly divided into three groups: control (ethanol treated, vitamin E-deficient group); 5% chamchwi (ethanol-treated, 5% chamchwi powder-supplemented group): 10% chamchwi (ethanol-treated, 10% chamchwi powder-suplemented group). Three groups of rats were suplemented with three experimental diets for 4 weeks and orally administrated 10% ethanol (v/v) daily via drinking water in the last experimental week. Contents of TBARS (thiobarbituric acid reactive substance). glutathione in liver and kidney and serum albumin were determined. The activities of superoxide dismutase (SOD), catalase and glutathione peroxidase (GSH-px) in liver and kidney were also analyzed. Relative weight of liver and spleen to body in chamchwi groups was lower than that in control group (p<0.05). The most remarkable result was that liver TBARS contents in chamchwi groups (5% chamchwi group, 46 $\mu\textrm{g}$ in MDA value; 10% chamchwi group, 35 $\mu\textrm{g}$) were significantly lower (p<0.05) than that in control group (66 $\mu\textrm{g}$). The supplement of chamchwi powder lowered the activity of manganese- superoxide dismutase (Mn-SOD), catalase in liver and GSH-px in kidney. The levels of glutathione in liver and kidney and serum albumin were not significantly different in all experimental groups (p<0.05). These results indicate that powdered herb of Aster scaber decreases lipid peroxidation and acitvity of Mn-SOD increased by alcohol-induced oxidative stress in liver of rats.
