In order to develop a potent antidandruffy agent from medicinal plants, various extracts of medicinal plants and herbs were prepared and investigated its antifungal activity against Malassezia furfur. Among 85 kinds of the secondary screened medicinal plants and herbs, water extract of Chrysanthemum zawadskii had the highest antifungal activity against dandruffy-producing Malassezia furfur. The antifungal compound was also maximally extracted when the powder of Chrysanthemum zawadskii was treated with water at $50^{\circ}C$ for 6 hours. The antifungal compound from Chrysanthemum zawadskii was partially purified by silica gel column chromatography and the partial purified compound was soluble at $70^{\circ}C$ for 20 min and pH $3.0{\sim}9.0$.

This study investigated the physicochemical and sensory characteristics of yanggaeng prepared with various amounts of Chrysanthemum zawadskii powder (as ratios of 0.5%, 1%, 1.5%, 2% to the total materials). The result displayed that the $^{\circ}Brix$ value, pH of yanggaeng decreased significantly with the addition of Chrysanthemum zawadskii powder. Increasing the amount of Chrysanthemum zawadskii powder in the yanggeng tended to increased acidity. In chromaticity determination, the values of lightness (L) showed a decrease. However, the value of redness (a) increased by increasing levels of Chrysanthemum zawadskii powder. Texture measurement scores in terms of hardness, springiness, and adhesiveness for yanggaeng showed that sample groups were lower than those of the control group. Cohesiveness and chewiness were higher in the additive group than in the control group. DPPH radical scavenging activity and nitrites cavenging activity were significantly increased Chrysanthemum zawadskii (p<0.001). The DPPH content was highest in the 62.40% Chrysanthemum zawadskii yanggaeng. As Chrysanthemum zawadskii powder increased, antioxidative activity also increased. Sensory evaluation scores in terms of color, odor, taste, texture, and overall preference of groups with 0.5% of Chrysanthemum zawadskii powder did not show any significant differences when compared to the control group. Based on the above results, this study suggests that the addition of 0.5% Chrysanthemum zawadskii powder may be the best substitution ratio for yanggaeng.

Chrysanthemum zawadskii var. latilobum (Compositae), which is called Gu-Jul-Cho, has been used as traditional medicine in pneumonia, bronchitis, common cold, pharyngitis, bladder-related disorders, women's diseases, and hypertension, etc. In this study we have investigated various biological activities of methanol extracts and their main component, linarin isolated from this herb. The antipyretic effect of them was tested by Brewers yeast method and the antiinflammatory activities, with arachidonic acid, o-tet-radecanoylphorbol 13-acetate and carrageenan. Their antipyretic and antiinflammatory activities were more potent than acetaminophene and aspirin. They also showed stronger hepatoprotective activities than ones of silymarin in mice.

This study was made on the taxa Chrysanthemum zawadskii complex that grow in South Korea on the basis of chromosomes, epidermis, pollens and gross morphology. I have found four types of chromosome numbers, 36, 45, 54, and 72 as a polyploidal series. Even though the gross morphology was quite similar almost the same gross morphology, chromosome number was different among the taxa. The taxa of 36 chromosomes present broad and fine lobed leaves which grow separately, broad leafed taxon in the mainland of Korea and the other's in Ullungdo Island which is isolated form the mainland in the East Sea. The taxa of 54 chromosomes are also present in the broad and in the fine lobed leaves. The fine lobed leave taxon grows in central to northern Korea and in the high altitude of mountains. Broad leafed taxon grows in central to southern Korea and comparatively lower altitude of the mountains. The taxon of 72 chromosomes is grown in the high altitude of Mt. Hallasan which is isolated from the mainland of Korea. According to this study of Chrysanthemum zawadskii complex, I have arranged the scientific names, as Chrysanthemum zawadskii subsp. latilobum, subsp. acutilobum, subsp. naktongenese, subsp. lucidum, subsp. coreanum and hybrid between subsp. acutilobum X subsp. latilobum.

This expriment was carried out to get basic information on composition and yield of aromatic constituents in leaves of four medicinal plants, Angelica tenuissima, Chrysanthemum zawadskii. ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris. Volatile aromatic constituents, 28 compounds in Angelica tenuissima were identified and 19 compounds were indentified in Chrysanthemum zawadskii ssp. latilobum. Volatile aromatic constituents, 23 compounds in Artemisia iwayomogi and Artemisia capillaris were identified. Major volatile aromatic consitiuents analyzed by GC/MS in four plants were $\alpha$-pinene, camphene, sabinene, cis-2-hexanol, and camphor etc. Content of essential oils in Angelica tenuissima, Chrysanthemum zawadskii ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris were 0.014, 0.275, 0.785, and 0.452%, respectively. As a result, it was suggested that a medicinal plant, Artemisia iwayomogi, was worthy of using as a useful material of perfume.

This study was conducted to determine the effect of growth regulators, genotype, and cutting position on the rooting and root growth from cutting of Chrysanthemum zawadskii H.. Rooting rate of Keungugeolcho in the treatement of IBA 500 and 1000 ppm was the better than those of other treatments of IAA, NAA and Rooton. Rooting rate differed depending on the genotype. Hangryobonggugeolcho was better than Keungucheolcho in rooting rate. The treatment of rooton remarkably induced many roots from the cuttings of eight accessions of Chrysanthemum zawadskii H.. Also, rooting rate and number of root differed depending on cutting position. When cuttings including shoot tip were cultured on tray containing bed soil, rooting rate and number of root induced from cuttings with shoot tip was higher than when cuttings without shoot tip and with lateral axillary bud were cultured.

The composition of essential oils from Chrysanthemum zawadskii var. latilobum and C. indicum were analyzed and compared. The results of gas chromatography-mass spectrometry revealed there were distinctly different compositional patterns between C. zawadskii var. latilobum and C. indicum essential oils. The combinatorial effect of the oil of C. zawadskii var. latilobum and C. indicum, with various antibiotics was assessed against antibiotic-susceptible and -resistant strains of Staphylococcus aureus and Streptococcus pneumoniae. The essential oil fraction significantly inhibited most of the tested antibiotic-susceptible and -resistant strains of S. pneumoniae, with minimum inhibiting concentrations (MICs) ranging from 0.5 to 4.0 mg/ml. The fractional inhibiting concentration indices (FICIs) of the oils when combined with antibiotics against S. aureus and S. pneumoniae ranged from 0.26 to 0.75, and showed synergistic or additive effects.

The volatile aroma constituents of Chrysanthemum zawadskii var. latilobum K. were separated by hydro distillation extraction (HDE) method using a Clevenger-type apparatus, and analyzed by gas chromatography-mass spectrometry (GC/MS). The yield of C. zawadskii var. latilobum K. flower essential oil (FEO) was 0.12% (w/w) and the color was light green. Fifty-five volatile chemical components, which make up 88.38% of the total aroma composition, were tentatively characterized. C. zawadskii var. latilobum K. FEOs contained 27 hydrocarbons, 12 alcohols, 7 ketones, 4 esters, 1 aldehyde, 1 amine, and 3 miscellaneous components. The major functional groups were terpene alcohol and ketone. Borneol (12.96), (${\pm}$)-7-epi-amiteol (12.60), and camphor (10.54%) were the predominant volatiles. These compounds can be used in food and pharmaceutical industries due to their active bio-functional properties.
