The peony patterns represent one of decorative designs with their fortunate and auspicious implications. The pattern emerged first from T'ang Dynasty, flourished during the periods of Sung and $Y\ddot{u}an$ in China, and then was introduced to Korea and Japan. For the purpose of systematizing the development of the pattern, this thesis is about the process of formation and various changes in peony patterns. It examines in general the literatures and the craft works, such as textiles, lacquer wares, chinas and porcelains, and metals. The characteristics of peony patterns are dealt respectively in this study about T'ang, Sung, $Y\ddot{u}an$, Ming and Ch'ing Dynasties of China, Shila, Korea, Chosun, of Korea, and Nara, Haian, Kamakura, Muromachi, MomoYama, Aedo of Japan.

This study was carried out to select proper intercrops in peony cultivation because peo­ny is damaged easily by disease and cannot make proper income with it's single crop system, so it needs rational intercropping system to raise it's productivity and income. The results of this study are as follows. The kinds of soil nematodes were Meloidogyne sp, Pratyienchus sp, Aphelenchoides sp, Ditylenchus sp, Xiphinema sp, and damaging dominant nematode was Meloidogyne sp. The density of Meloidogyne sp wa suppressed remarkably in the combination of peony+sesame, and peony + job's tears. This study shows that sesame and job's tear were most resistant crops to the IvIeloi­dogyne sp. The quanity of herbaceous peony was the best in the combination of peony+red pepper. The results of income analysis per lOa for three years shows next conclusion. Peony+red pepper combination and peony+ sesame combination were most effective when it's compared with single cropping of peony (1,490 thousand won). But red pepper was damaged easily by soil nematode, therefore, sesame was the most stable and high yield crop as a intercrop in the cultivation of herbaceous peony.

This experiment was carried out to investigate the effects of various fertilizers on the growth and yield of tree peony Moutan cortex RADICIS from 1990 to 1994. The paeonol content, a main medical ingredient of tree peony, was 0.5% in the control, and the contents of the chemical fertilizer(N-P-K) and the two-kind compound fertilizer treatments were $0.26{\sim}0.41%$, and those were lower than $0.40{\sim}0.45$ of the compost, the fowl dropping manure and the organic fertilizer treatments. The weights off dry root(radix) rind were increased by 42% in the fowl dropping manure treatment and by 49% in the compost treatment compared with 151kg/10a in the control. All things considered, compost, fowl dropping manure and organic fertilizer were more effective than chemical fertilizers for the culture of tree peony.

Effect of pretreatment processing (peeling time, drying temperature, sample type) on the quality of hot air drying peony roots was investigated. Peony roots were peeled for 0, 10, 20, 30, 60, 90 and 120 minute in the peeling machine after water washing. Sample types were whole or cut (thickness of 3mm). Temperatures of hot air drying were 30, 40, 50 and $60^{\circ}C$ The level of water contents in dried sample was $14{\sim}15%$. Drying time was muth reduced as the peeling time, cutting sample types and higher temperature. Contents of paeoniflorin were maintained highest amount (3.48%) in the non-peeling cut sample dried at $30^{\circ}C$ and lowest amount (2.29%) in the 120min-peeling whole one dried at $60^{\circ}C$. Skin color of dried peony roots was heavily discolored in the sample of non-peeling whole type dried at $60^{\circ}C$ and the color was dark brown $({\Delta}E\;was\;46.1)$. When considering shortening of drying time, preservation of active compounds and maintenance of color, the best pretreatment method of drying in peony roots was non-peeling, cut type processing.

This study was conducted to evaluate physiological activity of flower extract of peony (Paeonia lactiflora Pall.) by hydrolysis and to use it as a valuable cosmetic ingredients. Four cultivar of peony flowers were extracted, and the highest active ingredient contents was selected, and that cultivar was used for hydrolyzing. The results showed that high concentration of hydrochloric acid (HCl) hydrolyzed, and biological hydrolysis using enzymes had no activity. The deglycosylation of peonidin 3,5-diglucoside occurred by hydrolysis. The hydrolysate contains 63.3 ppm of peonidin, a red-colored anthocyanin compound. The antioxidant activity of hydrolysate was compared with extract. The results showed the strong antioxidant activity in hydrolysate (96%) than extract (82%). In addition, hydrolysate of peony flower showed higher inhibitory activity of NO release than extract. UVA assay using fibroblast cell (CCD-986Sk) showed that hydrolysate increased cell viability than extract under UVA exposure. Based on these results, we anticipate that hydrolysate of peony flower can be used a valuable cosmetic ingredient.

This study was conducted to find to change of component by different species, plant parts and growth stage of Paeonia lactiflora Pallas Among the species of peony, the contents of compounds was higher in cultivated peony (P. lactiflora P.) as compared with wild peony (P. japonica M., P. obobata M., P. anomala L.). Amount of methyl gallate was highest in 0.45% at Euisung jakyak. Amount of compounds in peony was the highest in 1.0% at paeoniflorin, followed by methyl gallate, astragalin and kaempferol in order. Contents of compounds with different growth stage were observed highest in April, and showed decreased trend in the later growth stage. Methyl gallate was present in 1.79% at petal, 0.56% at leaf and 0.01% at root, astragalin present at 0.27% at petal, 0.20% at leaf and 0.03% at root, and paeoniflorin present at 0.43% at petal, 1.09% at leaf and 2.52% at root.

Genetic polymorphism and molecular authentication were investigated with the commercial medicinal herb, Peony (Paeonia spp.), using random amplified polymorphic DNA (RAPD) markers. To identify the polymorphism of the RAPD patterns among plant origins, 20 different random primers were applied to the genomic DNA extracted from Paeonia spp. plants such as Paeonia (P.) lactiflora, P. officinale and P. japonica. Ten primers out of 20 primers could be used to discriminate the plant species in the same genus and 72 out of 81 scored DNA fragments (88.9%) generated with these primers were polymorphic. Especially, four primers, such as OPA1, OPA3, OP9, and OPA13, were useful to discriminate the plant origins among the species of Peony. In the results of cluster analysis using RAPD data obtained from the 10 primers, Peony (Paeonia spp.) plants used in this study were grouped into the two distinctive clusters, genetically. Herb medicine, especially P. lactiflora, were easily identified, when species-specific primers were applied to the investigation for discriminating herb medicine currently traded in domestic herb market, Kyungdongmart. Consequently, RAPD analysis was useful method to discriminate plant origins and the commercial medicinal herbs, Paeonia spp..

The experiments were conducted to determine the influence of seed size and mucilaginous substance on seed germination of herbaceous peony collected from farmers' fields in Korea. No significant difference was recognized between the size of seed and the rale of germination. The maximum percentage(68%) of seed germination was obtained from the seeds with thin brown colour treated at $20^{\circ}C$. The amount of mucilaginous substances exuded from peony seeds was the highest in the seeds with black brown colour. Germination rate of peony seeds was negatively correlated with the amount of mucilaginous substance exuded from the seeds. High frequency(93%) of seed germination was obtained from the seeds which treated in the mixture(1:1) of sands and activated charcoal.

The ethanol extract of peony root (Paeonia Lactiflora Pall, Paeoniaceae) and its major active components including gallic acid and methyl gallate were evaluated for their protective effects against free radical generation and lipid peroxidation. And protective effects against hydrogen peroxide-induced oxidative DNA damage in a mammalian cell line were performed. The ethanol extract of peony root (PRE), gallic acid and methyl gallate were shown to possess the significant free radical scavenging effect against 1,1-diphenyl-2-picryl hydrazine (DPPH) radical generation and were revealed the inhibitory effect of lipid peroxidation as expressed by malondialdehyde (MDA) formation. They were also found to strongly inhibit hydrogen peroxide-induced DNA damage from NIH/3T3 fibroblasts, assessed by single cell gel electrophoresis. Furthermore, oral administration of 50% PRE (50% ethanol extract), gallic acid and methyl gallate potently inhibited micronucleated reticulocyte (MNRET) formation of mouse peripheral blood induced by KBrO3 treatment in vivo. Therefore, PRE containing gallic acid and methyl gallate may be a useful natural antioxidant by scavenging free radicals, inhibition of lipid peroxidation and protecting oxidative DNA damage.

The purpose of this study is to analyze the aesthetic characteristics of traditional Korean patterns appearing on fashion collections from 1990 to 2005. Traditional Korean patterns have been used as an important element to express a Korean image since the 1990s. Frequently used patterns included several kinds of geometric patterns, plant patterns(flower, peony, Four Gracious Plants), and Chinese character patterns. Specifically, since the 2000s, animal patterns such as tiger, Chinese phoenix, and giraffe which were not often used, plant patterns such as arabesque, peony, and flower, and a variety of Chinese character patterns appeared. For the expression techniques, while embroidery and printing was often used in the 1990s, they became varied into printing, beading, embroidery, gold and silver leaf, and hand painting after 2000 as a result of designers' active attempts. The aesthetic characteristics of fashion design with its focus on traditional patterns were analyzed. First, Chinese character patterns and phoenix pattern which were mainly used for a court suit, and show the excellence and unique originality of Korean culture. Second, traditional Korean patterns directly and indirectly imply symbolistic significance of lucky sign and illustrate the use of various lucky sign patterns. Third, traditional Korean patterns such as arabesque or peony were expressed by colorful embroidery to add decorative beauty. Finally, traditional Korean patterns reflect a naturalistic worldview and are completed finished as the design.
