  • Some biological activities such as an electron donating capacity, the contents of total polyphenol compounds and flavonoids, fibrinolytic activity and $\alpha$-glucosidase inhibitory activity have been detected in hot water extracts of Ligularia fischeri and Angelica gigas Nakai. To increase the usefulness of the functional ingredients for prevention and improvement of some metabolic disorders, ethanol-treated hot water extracts of Angelica gigas Nakai were prepared. A hot water extract of Ligularia fischeri has 92% of electron donating capacity, 39.4 mg/g of total polyphenol compounds, 24.8 mg/g of flavonoids and 29.8% of $\alpha$-glucosidase inhibitory activity, but no fibrinolytic activity. A hot water extract of Angelica gigas Nakai has 94.7% of electron donating capacity, 5.8 mg/g of total polyphenol compounds, 2.6 mg/g of flavonoids, 0.48 plasmin units of fibrinolytic activity and no $\alpha$-glucosidase inhibitory activity. However, with partial purification using cold ethanol treatment, the $\alpha$-glucosidase inhibitory activity of Angelica gigas Nakai was increased to 70.5%. Thus, we expected a more useful effect with the use of the addition of a cold ethanol-treated Angelica gigas Nakai extract. The L, b values of cold buckwheat noodles using a mixture of 0$\sim$3% of Ligularia fischeri powder and 0.5% of an ethanol-treated hot water extract of Angelica gigas Nakai were decreased with the addition of an increasing amount of Ligularia fischeri powder. Among the mechanical qualities, only adhesiveness was significantly higher in 3% Ligularia fischeri noodles. From sensory evaluation data, it was determined that these two functional ingredients did not ruin the color, texture, and overall acceptance of the cold buckwheat noodles. A higher amount of the extracts improved the quality of the product with little added cost.

  • This study aims to confirm the possibility of using the invasive alien plants in Jeju as a functional biomaterial. To achieve this purpose, 70% ethanol extract and solvent fractions were prepared for five invasive alien plants (Hypochaeris radicata, Rumex acetosella, Humulus japonicus Siebold & Zucc., Solanum viarum, Lactuca scariolar) and their antioxidant, antibacterial anti-inflammatory and anti-obesity effects were investigated. The DPPH radical scavenging activity of ethanol extract from invasive alien plants was shown in the order of Rumex acetosella > Hypochaeris radicata > Humulus japonicus. Antimicrobial activity of ethanol extract against food poisoning bacteria (4 species) and oral cavity-induced microorganisms (6 species) was measured. As a result, the extract of Humulus japonicus showed high antibacterial effects against food poisoning bacteria (E. coli, V. parahaemolyticus) and oral microbes (L. casei, S. epidermidis, E. faecalis). In LPS-induced RAW 264.7 cells, the anti-inflammatory effect of ethanol extract from invasive alien plants was investigated. As a result, the NO production inhibition activity was highest in the Rumex acetosella and the Humulus japonicus Siebold & Zucc. ethanol extract, and the NO production inhibition activity was concentration-dependent. In addition, the Rumex acetosella and the Humulus japonicus Siebold & Zucc. ethanol extract showed a concentration-dependent inhibitory effect on cytokine (IL-6) production. These extracts also showed inhibitory activity of COX-2, an inflammatory protein. This suggests that NO production inhibition activity by the extract of invasive alien plants is the result of inhibition of iNOS and COX-2 expression. Currently, organic solvent fractions of crude extract are manufactured and the investigation of active ingredients is continuing along with evaluation of biological activity such as anti-inflammatory. These results are expected to be a major data for the study on the separation and utilization of active ingredients with antioxidant, antibacterial and anti-inflammatory effects using foreign plant crude extract and solvent fractions, and are highly likely to be applied to the development of functional food and cosmetics materials.

  • Cholesterol is a vital component of the human body. It stabilizes cell membranes and is the precursor of bile acids, vitamin D and steroid hormones. However, cholesterol accumulation in the bloodstream (hypercholesterolemia) can cause atherosclerotic plaques within artery walls, leading to heart attacks and strokes. The efficiency of cholesterol absorption in the small intestine is of great interest because human and animal studies have linked cholesterol absorption with plasma concentration of total and low density lipoprotein cholesterol. Cholesterol absorption is highly regulated and influenced by particular compounds in the food supply. Therefore, it is desirable to learn more about natural food components that inhibit cholesterol absorption so that food ingredients and dietary supplements can be developed for consumers who wish to manage their plasma cholesterol levels by non-pharmacological means. Food components thus far identified as inhibitors of cholesterol absorption include phytosterols, soluble fibers, phospholipids, and stearic acid.

  • Recently, the number of customers who want natural cosmetics without petroleum originated cosmetic ingredients is increasing over the world, however, there are few natural cosmetics that claim functionality in the products. Because there are few functional cosmetic ingredients from nature and though so, it is very difficult to stabilize the final products manufactured by using those functional cosmetic ingredients in the long period. This study is on stabilization of oleanolic acid, insoluble anti-wrinkle cosmetic ingredients from nature, with hydrogenated lecithin in the solubilization product, aiming for developing a formulation of solubilization products which can be certified as organic cosmetics. In case of other synthetic solubilizers, they showed unstability at $45^{\circ}C$ within 2 ~ 3 days, however, for natural origin hydrogenated lecithin a stable product was made without particle size change during 4 weeks. The stability of oleanolic acid in the solubilization product was measured for 24 weeks at $25^{\circ}C$ and $40^{\circ}C$, both samples showed over 90 wt% value of the initial one, which can prove that oleanolic acid was stabilized in the product without any degradation. Also through clinical tests, the effect of moisturizing, anti-wrinkle, safety were confirmed.

  • The main objective of this study was to investigate possible application of citron (Citrus junos Sieb. ex TANAKA) seeds, which are massively produced as by-products during citron tea process, into functional food materials. First of all, citron seeds were germinated and produced citron shoots were examined for their functional properties. When contents of flavonoids in citron seeds and their germinated shoots were compared, naringenin, neohesperitin, and hesperitin were remarkably increased in shoots after germination while naringin and didymin were decreased. Concentrations of limonin and nomilin were decreased by germination otherwise their unidentified derivatives were newly formed. A methanol extract of citron shoot had lower $IC_{50}$ values [0.13 and 0.07 mg/mL for 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and ABTS, respectively] than citron seed extract in radical scavenging activities. Addition of 500 mg/mL of citron shoot extract suppressed fat accumulation in 3T3-L1 adipocytes by 36.9%. Oral administration of olive oil along with citron shoot extract (33 mg/kg body weight) to Sprague Dawley rats effectively inhibited absorption of lipid into a body by decreasing blood triglyceride levels from 105.1 to 74.9 mg/dL 2 hr after olive oil administration. According to these results, citron shoot extract as a rich source of flavonoids can be utilized for functional food ingredients with effective antioxidant and anti-adipogenic properties.
