  • This study was conducted to investigate the uses of Aster scaber. The survey methodology employed was a questionnaire, which was used to interview 272 (37.8%) males and 448(62.2%) females from the Seoul and Kyunggido areas. The main results are as follows: 40-50 years old like and eat Aster scaber more frequently than 10-30 years old. The most popular reason provided for the preferance of Aster scaber was good health benefits. People indicating a dislike for Aster scaber had generally fewer previous experiences of eating this plant. Respondents who regularly ate healthy foods preferred prepared Aster scaber to others foods(p < .001). The main purchasing place was traditional markets and supermarkets. The main cooking method was boiling with addition of seasoning. Aster scaber was purported as having the following characteristics "low calories and thus great as diet food'(4.03), 'ability to prevent adult disease'(3.95), 'high in vitamins and minerals'(3.89), and 'high fiber content which prevented constipation'(3.85). However, it was not associated with 'astringent taste'(3.51) and was regarded as 'fat accumulation restrainer and remover of heavy metal'(3.53). Recognition and eating experience was low for Aster scaber kimchi and rice bread, bread, sauce and Aster scaber added health drinks. However opinion of its taste was regarded highly.

The extraction yield was higher in the Aster scaber cultivated field than those of the Aster scaber in the wild field, and high from the dried Aster scaber. The total polyphenol and flavonoid contents of Aster scaber hot-water extracts from the wild field were higher than those in the cultivated field. The total polyphenol contents were high in the extract of blanched and dried Aster scaber, and the flavonoid content was high in the non-treated Aster scaber. The electron donating ability (EDA) values of Aster scaber hot-water extracts were increased along with the increase of extract concentration, while the EDA of the blanched and dried Aster scaber extracts was higher than the other extracts. Furthermore, the SOD-like activity was increased by the extract concentration, and was high in the extract of the non-treated Aster scaber. The nitrite scavenging ability in pH 1.2 was high in the non-treated, blanched, dried, and natural dried Aster scaber. The xanthine oxidase inhibitory activities were increased through the increase of extract concentrations, and higher in the hot-water extract from Aster scaber in the wild field (WRA) than those in the other extracts. The inhibition of tyrosinase and reduction of power were increased by the increased extract concentration, and high in the extracts of blanched and dried Aster scaber. The reduced power was higher in the Aster scaber hot-water extracts of cultivated field, and was higher in the extracts of blanched and dried Aster scaber than those in the extracts dried through the use of other drying methods. Aster scaber has a high content of polyphenol and flavonoid, and antioxidant activities, which were developed as functional materials.

  • Growth responses of some intestinal bacteria such as bifidobacteria and Clostridium perfringens to the extracts of certain foodstuffs were investigated in vitro. Among edible mountain herbs, the extracts of several chui-na-muls (Aster tataricus, Ligularia fischeri and Aster scaber) had an inhibitory activity against C. perfringens on the agar plate and the water extract of Aster scaber worked selectively on it among intestinal bacteria. The water extract showed growth-promoting effect toward bifidobacteria such as B. adolescentis, B. animalis, B. bifidum, B. infantis and B. thermophilum in the broth culture. When the faecal inoculum was incubated in the culture with the extract, the population of C. perfringens decreased, whereas that of bifidobacteria increased by $10^3$ scale.$\beta$-glucuronidase activity in the culture with the water extract of Aster scaber digested with pepsin and pancreatin was lower than that in the control culture.

  • 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 purpose of this study was to evaluate the antioxidative potential of Korean wild leafy vegetables in vivo as well as in vitro. Antioxidative activities of Aster scaber and Ligularia fischeri were evaluated against a reference of Spinacia oleracea Forty rats were fed either control diet or respective vegetable diets for four weeks. The level of thiobarbituric acid reactive substances (TBARS) and the activities of catalase and superoxide dismutase (SOD) in liver were compared. The plasma concentrations of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and triglyceride (TG) were also compared. Korean wild leafy vegetables were assayed for $\beta$-carotene, vitamin C and vitamin E and total phenolic compound including flavonoid and thiobarbituric acid (TBA) value using the linoleic acid model system. SOD activity in rats fed Aster scaber was significantly higher(as much as 289%) than those fed Spinacia oleracea. Compared to control animals, the Aster scaber fed animals had significantly lower TC and lower atherogenic index. Compared to Spinacia oleracea, Aster scaber and Ligularia fischeri had vitamin C concentration of 150% and 400%, flavonoid concentrations of 470% and 310%, and phenolic compound concentrations of 326% and 203%, respectively, but tended to have lower $\beta$-carotene and significantly lower vitamin E concentrations. TBA values were only 18% of the control value in Aster scarier and Ligularia fischeri and 41% of the control value in Spinacia oleracea. These results suggest that Aster scaber could have potent antioxidative activity in vivo as well as in vitro and potential vague as a functional food to improve the plasma lipid profiles. Furthermore, phenolic and flavonoid compounds may be a major contributing factor to the antioxidative potential of Korean wild leafy vegetables.

  • To determine the optimum extraction conditions that give the highest yield of isoquercitrin and caffeic acid from Aster scaber, the effects of four extraction variables (solvent concentrations, extraction time, number of repeated extraction, and solvent volumes) on isoquercitrin and caffeic acid yield was examined via HPLC-UV. Our results showed that the highest extract and isoquercitrin yield were observed when A. scaber was extracted with 450 mL distilled water for 8 hr repeatedly for three times. In case of caffeic acid, the content was higher in the two repeated extracts. Also, content analysis of isoquercitrin in Aster species was performed in which A. fastigiatus, A. ageratoides, and A. scaber exhibited the highest isoquercitrin content at 6.39, 5.68, and 2.79 mg/g extract, respectively. In case of caffeic acid, the highest content of A. scaber and A. glehni was 0.64 and 0.56 mg/g extract, respectively. This study reports an optimized method for extraction of isoquercitrin and caffeic acid from A. scaber and evaluates potential sources of the compounds.

  • This study was performed to investigate the effects of dried powder and juice of Aster scaber on lipid metabolism and antioxidative capacity in rats. Twenty one male Sprague-Dawley rats weighing 170.9$\pm$15.1g were blocked into 3 groups according to body weight and raised for 4 weeks with diets containing 5%(w/w) dried powder and juice from the same amount of Aster scaber. Food intake, body weight gain, food efficiency ratio and organ weights were not different among all the experimental groups. On lipid metabolism, both dried powder and juice supplementation decreased plasma total lipid, triglyceride(TG), total cholesterol and liver cholesterol levels by increasing fecal lipid excretions. Plasma thiobarbituric acid reactive substance(TBARS) concentrations were significantly decreased in dried powder and juice groups, whereas liver TBARS concentrations were not affected by experimental diets. Red blood cell(RBC) superoxide dismutase(SOD) activities were significantly increased by dried powder and juice supplementation, while activities of other antioxidative enzymes in RBC and liver were decreased or showed no changes. In conclusion, both Aster scaber dried powder and juice had the effects on lowering lipid levels by increasing fecal lipid excretions, and inhibiting of plasma lipid peroxidation in animals and the effects of juice were higher than that of dried powder.
