  • This study investigated the effects of image on the preference and intake frequency of 19 vegetables. A total of 359 usable surveys were collected using a convenient sampling method. The subjects included females (51.8%), university students (50.7%), home residents (66.9%) and subject's spending 20,000~40,000 won on meals/week (41.5%) and eat out 2~3 times/week (29.5%). The intake frequency of vegetables was 2~3 times per month. The healthy image of all vegetables was good overall and the average preference was 3.78 (out of 5 on the Likert). Tomatoes had the healthiest image, onions the highest preference, and Korean cabbage the highest intake frequency. For males, the vegetable with the healthiest image was sesame leaf, while the healthiest foods for females were broccoli and tomatoes. Elementary students had a healthier image of cucumber, bean sprouts, radish, sesame leaf, lettuce, radish leaf, and cabbage than university students and adults. Home residents had a healthier image of cabbage and burdock than other types of residents. Subject that st over 20,000 won per week on meals had a higher image of most vegetables. In terms of preference, males liked Korean cabbage, green pumpkin, balloon flower roots, radish leaf, and lotus root, but female liked tomatoes. In addition, elementary students, home residents, and subjects who eat out less often tended to prefer vegetables. In terms of intake, there was a high frequency of intake for all vegetables in adults. Home residents specifically had a higher intake of cucumber, carrot, bean sprouts, spinach, green pumpkin, balloon flower roots, lettuce, radish leaf, broccoli, burdock, lotus root, and tomato. Overall, the healthy image of vegetables had a positive influence on their preference and intake frequency. Therefore, to encourage the intake of vegetables, direct or indirect variables should be examined.

  • Soil properties and heavy metal (HM) concentrations in the field soils where balloon flowers (Platycodon grandiflorum, BF) were cultivated, were investigated together with HM (Cd, Cu, Pb, and Zn) accumulation by the BF roots. Basically, in most soils examined (51-97% among 65 samples), the chemical properties including soil pH, organic matter, available-P, and exchangeable cation contents appeared to be lower than the optimal ranges for balloon flower cultivation. There were no samples exceeding the standard limits for HM in soils. Instead, the total HM concentration levels in soils appeared to be maintained at around background levels for general soil in Korea. This implied that elevated HM accumulation in the soils caused by any possible input sources was unlikely. Even though the BF cultivated soils were not contaminated by HM, it was appeared that substantial amount of Cd was accumulated in BF roots with 1.5% and 35% roots samples exceeding the standard limits legislated for BF root ($0.81mg\;kg^{-1}DW$) and herbal plants ($0.3mg\;kg^{-1}DW$), respectively. This implied that the soil HM standard limits based on the total concentration does not reflect well the metal accumulation by plants and also it is likely that the Cd standard limits for BF and herbal plants is too restrict.

  • This study was conducted to identify transition characteristics of mercury in several selected medicinal plants and to find the appropriate management for production of safety food. Cultivated soils and medicinal plants were collected at 29 sites for Angelica gigas (Korean angelica root), 68 sites for Platycodon grandiflorum (Balloon flower), 35 sites for codonopsis lanceolata (Deoduck), 36 sites for Dioscorea batatas (Chinese yam), 32 sites for Rehmannia glutinosa (Foxglove), 16 sites for Cnidium officinale makino (cnidium), and 26 sites for Astragalus membranaceus (milk vetch root) during the harvest season of 2013. Mercury in the soils and medicinal roots were analyzed with a Direct Mercury Analyzer. Average content of mercury in soils cultivated medicinal plants was $0.023mg\;kg^{-1}$ (range: from 0.003 to $0.074mg\;kg^{-1}$) and average content of mercury in medicinal plants was $0.003mg\;kg^{-1}$ (range: from 0.001 to $0.011mg\;kg^{-1}$), indicating that mercury in the surveyed soils and medicinal plants were not exceeded the Korean regulation.

  • Platycodon grandiflorum (balloon flower) root (Platycodi radix, PR) is used as a health supplement owing to its beneficial bioactive properties. In the present study, the anti-inflammatory, antioxidant, and whitening effects of deglycosylated platycosides (saponins) from PR biotransformed by pectinase from Aspergillus aculeatus were investigated. The bioactivities of the platycosides improved when the number of sugar moieties attached to the aglycone platycosides was decreased. The deglycosylated saponins exhibited higher lipoxygenase inhibitory activities (anti-inflammatory activities) than the precursor platycosides and the anti-inflammatory compound baicalein. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity of the pectinasetreated PR extract was higher than that of the non-treated PR extract. The trolox-equivalent antioxidant capacity (TEAC) assay showed improved values as the saponins were hydrolyzed. The tyrosinase inhibitory activities (whitening effects) of deglycosylated platycosides were higher than those of the precursor platycosides. Furthermore, 3-O-β-ᴅ-glucopyranosyl platycosides showed higher anti-inflammatory, antioxidant, and whitening activities than their precursor glycosylated platycosides. Therefore, 3-O-β-ᴅ-glucopyranosyl platycosides may improve the beneficial effects of nutritional supplements and cosmetic products.

  • This study was designed to investigate effects of lobster shrimp chitosan on serum and liver lipid levels in rats fed high fat and cholesterol diets. Male Sprague-Dawley rats of 4-weeks old, weighing 70$\pm$5g, were fed experimental diets for 3 weeks: basal diet+5% cellulose(group 1), high lipid diet+5% cellulose(group 2, control group), high lipid diet+5% balloon flower root(group 3), high lipid diet+5% cellulose(group 4, high lipid diet+5% lobster shrimp chitosan(group 5). Concentrations of total cholesterol, HDL-cholesterol, LDL-cholesterol, free cholesterol, cholesteryl ester, triglyceride, phospholipid in serum and liver were determined. The results obtained were as followes: Serum total cholesterol concentration were significantly reduced in all supplemented group compared with control. HDL-cholesterol concentrations were higher in groups 1, 4, and 5 and the ratios of HDL-cholesterol to total cholesterol concentration were higher in groups 1, 4, while the atherogenic-indices were lower in groups 1, and 4 than control. Concentrations of LDL, LDL-cholesterol and free cholesterol, cholesteryl ester were significantly lower in all supplemented groups than the control group. Concentrations of phospholipid and triglyceride were lower in groups 3, 4, 5, while activities of GPT and GOT were significantly lower in groups 4, 5 than the other group. Concentrations of calcium, magnesium and phosphorous were high in all treatment groups compared to the control group. Liver contents of total cholesterol, free cholesterol and cholesteryl ester were lower in the groups 1, 3, 4, and 5 than in the control group, especially lower in groups 1, and 5. Liver triglyceride and phospholipid concentrations were significantly lower in the groups 1, and 5 than in the other groups. The results from the data suggested that the experimental diet containing 5% lobster shrimp chitosan was effective to reduce the serum and liver lipids.

  • 식물 내생균 Bacillus sp. CY22는 식물병원균 Rhizoctonia solani, Fusarium oxysporum 및 Phythium ultimum에 대해 강한 항균력을 나타내었다. 일반적으로 많은 Bacillus속 균주들은 iturin, fengycin, mycosubtulin과 같은 항균 물질을 분비한다. 본 연구에서는 식물내생균 Bacillus sp. CY22의 배양액으로부터 항균물질을 분리, 정제하였으며 MALDI-TOF mass로 분자량을 확인하였다. MALDI-TOF mass spectrum분석 결과 분리된 항균물질은 Bacillus 속 균주가 생성하는 항균물질로서 잘 알려져 있는 iturin의 분자량과 거의 일치하였으며, m/z 1043.4, 1057.4, 1071.4에서 molecular ion peak를 나타내었다. 이들은 각각 m/z 14차이를 가진 iturin의 isoform으로 추정되며 이 것은 iturin을 구성하고 있는 지방산의 탄소수 차이로 생각되며 m/z 1065.4, 1079.4 peak는 sodium adduct로서 추정된다. 또한 항균물질 iturin을 생성하는데 관여하는 transacylase 유전자를 크로닝하여 ita22 유전자로 명명하고, 그 특성으로 ita22 유전자는 400 개의 아미노산을 인지하는 1,200 bp의 open reading frame (ORF)을 가지며, 아미노산의 상동성을 조사한 결과 Bacillus subtilis 168의 FenF (BAB69697)와 가장 유사하였다.
