The physicochemical and sensory characteristics of Yakju fermented with different ratios of Taraxacum platycarpum (dandelion) root powder (0, 5, 10, and 15%) were investigated. The pH of Yakju decreased and the total acidity and sugar content increased according to the addition of dandelion root powder. Dandelion root powder (15%) showed significantly higher reducing sugar content on the 3rd day of fermentation compared with other groups, including the control. Also, further exposure of fermentation time showed a declining pattern of reducing sugar content. Including control, the alcohol content increased in all Yakju samples fermented with dandelion root powder as fermentation progressed. The Yakju fermented with 5% dandelion root powder showed the highest sensory scores for color, aroma, taste, swallowing, and overall acceptability as $6.38{\pm}1.27$, $5.58{\pm}1.02$, $5.79{\pm}0.98$, $6.08{\pm}1.21$, and $5.96{\pm}0.91$, respectively. In the present study for the production of Yakju, 5% dandelion root powder was the most appropriate amount to be added for the production of Yakju. The result obtained here may provide fundamental data for the traditional Yakju industry, which is interested in using a variety of natural resources.

The in vivo and in vitro effects of oriental herb extracts of Cassia obtusifolia, Taraxacum platycarpum and Ulmusmacrocarpa on anti-atopic allergic reaction were evaluated in this study. A mixture of these extracts exhibited more potent anti-allergic activities in human mast cells than those from individual extracts. The herbal mixture significantly inhibited the release of compound 48/80-induced $\beta$-hexosaminidase release in the human mast cell line, HMC-1. The mixture also suppressed the production of PMA and A23187-induced inflammatory cytokines in HMC-1 cells. To further investigate the in vivo effects of the herbal mixture, a Dermatophagoides farinae (DF)-induced atopic dermatitis mouse model was utilized. Oral administration of the herbal mixture significantly decreased the ear thickness and swelling in DF treated NC/Nga mice in a dose dependent manner. Furthermore, serum levels of IgE and interleukin-4 (IL-4) were significantly decreased, whereas interferon-gamma (IFN-$\gamma$) levels were increased in the mixture administrated groups when compared to the control. Taken together, our data indicate the possibility of using a mixture of the oriental herb extract to relieve symptoms of atopic dermatitis.

The polysaccharide fraction from Taraxii Herba showed potent immunopotentiating activities with antitumor activities. The fraction having small amount of protein inhibited the growth of solid tumor and increased peritoneal exudate cells and immunoorgan weights in normal mice, and also increased hypersensitivities in tumor bearing mice.

Collected germplasms of five representative dandelion species (Taraxacum ohwianum, T. platycarpum, T. platypecidum, T. officinale, and T. coreanum) were 104 lines from different habitates in Korea and China. Their genetic diversity was analyzed by genomic fingerprinting method using amplified fragment length polymorphism (AFLP). AFLP results of 6 primer combinations were revealed 1,176 total DNA fragments and 523 polymorphic bands with a 44.4% ratio of polymorphism. On the basis of similarity coefficient analysis by unweight pair group method with arithmetic averages (UPGMA), 104 dandelion germplasm lines were ranged from 0.64 to 0.99 and clustered distinct five group depending on the species. Furthermore, a principal coordinate analysis (PCA) by the application of multi-variate analysis indicated significantly greater differences among species than geographical origins.

Antimicrobial activity of dandelion(Taraxacum platycarpum D.) was investigated. Methanol extract of dried dandelion was fractionated to hexane, chloroform, ethylacetate, butanol and aqueous fraction. Ethylacetate fraction among these fractions showed the highest inhibitory effect on the microorganisms such as B. subtilis, L. monocytogenes, S. aureus, E. coli and V. parahaemolyticus at $500\mu\textrm{g}/disc$. Ethylacetate fraction was further fractionated into 13 fractions by silica gel column and thin layer chromatography(TLC). The results showed that ethylacetate fractions No. 4, 5 and 6 had high antimicrobial activity. These were mixed again, re separated and five fractions were obtained. Among them, No. 2 fraction had the highest inhibitory effect on the microorganisms, which was then separated into six fractions. In the 3rd fractionation, No. 3 fraction was identified as benzoic acid by HPLC, $^{1}H-NMR$ and GC MS.

Certain parts of 95 species of edible and medical plants were extracted with water and 75% of ethyl alcohol. After addition of those extracts to palm oil, lard and soybean oil at different level, their antioxidative activities were compared by Rancimat test. Six species among them seemed to have rather strong antioxidative activity and high extracting yields(i.e. Taraxacum platycarpum, Plantago asiatica, Rhus javanica L., Lycopus lucidus, Astragalus membranaceus, Taraxacum platycarpumH). Among them, the Rhus javanica L. ethanol extract retarded greatly the induction period of palm oil and lard. When 600 ppm of Rhus javanica L. extract were added to palm oil and lard, AI(antioxidant index was expressed as induction period of oil containing various plant extracts/induction period of control oil) of each was 1.35 and 3.03 respectively. This result indicated that the Rhus javanica L. extract was more effective on lard than the other oils.

Extracts of 13 medicinal plants were tested to investigate the improvable effects on microflora growth in the intestines of human. Water extracts of Artemisia capillaris, Taraxacum platycarpum and Ethanol extracts of Allium tuberosum, Artemisia capillaris, Artemisia vulgaris, Plantago asiatica, Schizandra chinensis, Sedum sarmentosum, Taraxacum platycarpum, Zingiber officinale inhibited the growth of C. perfringens. Water and ethanol extracts of Sedum sarmentosum, Schizandra chinensis inhibited the growth of E. coli. While 13 medicinal plants were not remarkably inhibited the growth of B. longum. Therefore, ethanol extracts of Schizandra chinensis, Sedum sarmentosum can be utilized as functional food materials to improve in the intestines.

Extract of Taraxacum platycarpum (AF-343) has been reported to have several biological properties such as skin hydration and anti-inflammatory effects. Although clinical evidences of skin hydration and antiinflammatory effect were proven in clinical trial, precise mechanism of skin hydration was not fully understood yet. In this study, we have focused skin hydration mechanism related filaggrin, collagen, and matrix metalloproteinase (MMP) in vitro and animal study. Herein, skin hydration mechanism of AF-343 is due to recovery of filaggrin in mice model and increased production of collagen with suppression of matrix MMP in vitro fibroblast cell line.

Taraxacum platycarpum (TP) has been used for years without restriction on usual dose for its non-toxic nature and nonexistence of the side effects. To develop antimicrobial hydrogel, poly (vinylalcohol) (PVA) hydrogels containing the aqueous extracted TP as an antimicrobial agent were prepared by using gamma-rays irradiation. The antimicrobial activities of the TP hydrogels were tested against Staphylococcus aureus and Staphylococcus epidermidis by disc diffusion method. The inhibition zones (IZ) of the TP extracts and TP hydrogels against S. aureus were 16 mm and 20 mm and against S. epidermidis was 10 mm and 13 mm, respectively. In conclusion, the TP hydrogel that has an excellent antimicrobial activity was proved to be a valuable material for functional skin care.
