To develop a natural antioxidant from three Chrysanthemum species, flower and shoot extracts of Chrysanthemum frutescens, Chrysanthemum morifolium and Chrysanthemum zawadskii ssp. naktongense were obtained and their phenolic compound contents, scavenging effects on DPPH and ABTS radicals, ferrous ion chelating effects and inhibition activity on lipid peroxidation of linoleic acid were studied. Shoots of C. morifolium showed the highest levels in all above mentioned analyses. Especially, shoot extract of C. morifolium had high scavenging activities on ABTS radicals, similar to ascorbic acid or BHT. Ferrous ion chelating effect was the lowest in a C. morifolium shoot extract, but the highest in a C. morifolium flower extract. Inhibition activity on lipid peroxidation of linoleic acid was the highest with C. frutescens and C. morifolium shoots, but activity was lower than BHT. From present study, a shoot extract of C. morifolium is demonstrated as a valuable source for the development of a natural antioxidant. However, due to its low levels of ferrous ion chelating effects and inhibition activity on lipid peroxidation, a combination of other antioxidants with C. morifolium extract is recommended for the development of a new antioxidant.

$SO_2$ gas injuries for 19 varieties of 10 species of plants were investigated within a environmentally controlled growth chamber. Visible injuries were observed when exposing the plants either 0, 0.2, 0.4, 0.7 or 1.5ppm of $SO_2$ gas for 5 days from 9 : 00 to 17 : 00 everyday. The results obtained were as follows: 1. Light brown spots were shown on Raphanus sativus(Chunchu, Taeback, Jinjudaepyung), Brassica campestris(Manchun, Josaengmiho, Seoul, Jeonseung), and Capsicum annum(Searona, Hongsanho, Hongilpum); brown spots on Sesamum indicum(Pungnyun, Kwangsan); reddish brown shades on Cleosia cristata; and black brown spots on Perilla frutescens, Calendula officinalis, Chrysanthemum morifolium, and Salvia splendens, respectively. 2. The spotty injuries induced by $SO_2$ gas injuries for 19 varieties of 10 species of plants were investigated within a environmentally controlled growth chamber.

Present studies were conducted to investigate the effects of water and 80% ethanol solvent on antioxidant activities of flower extracts of Chrysanthemum frutescens, Coreopsis lanceolata, Matricaria recutica, and Hieracium pilosella. Extraction yields of water extracts ranged 27.15~40.25% and 80% ethanol extracts 24.92~42.84%, respectively. In all species polyphenol and flavonoid contents were higher with 80% ethanol extraction, especially in C. lanceolata. Same results were obtained with scavenging effects on DPPH and ABTS radicals and ferrous ion chelating effects. Scavenging activity of flower extracts on DPPH radicals was highest in H pilosella - higher than that of synthetic antioxidant DHT. Higher scavenging activity on ABTS radicals was observed with M. recutica. Generally Compositae flower extracts exhibited higher scavenging activity on ABTS radicals than DPPH. Scavenging activity on ABTS radicals of M. recutica and P pilosella were superior to those of ascorbic acid and BHT. Ferrous ion chelating effects were much higher with H. pilosella flower extracts by 80% ethanol. Chelating effects of 4 species were much lower than those of EDTA. In conclusion, to develop natural antioxidant from above 4 Compositae species, 80% ethanol is recommended for efficient solvent to obtain maximum antioxidant isolation and activity.

Recently, consumer demand for functional cosmetics containing natural ingredients has been greatly expanded. To develop the natural cosmetic materials, we selected 3 plants, Chrysanthemum zawadskii Herbich (CZ), Perilla frutescens (L.) Britton var. acuta Kudo (PF), and Rosa multiflora Thunberg (RM) which showed high total flavonoid contents (TFC), total polyphenol contents (TPC), and strong DPPH radical scavenging effect. We determined astragalin, chlorogenic acid, and rosmarinic acid as a marker compound for quantitative analysis of the content of each material and standardization of the quality standards and manufacturing standards through LC/MS analysis. HPLC-DAD was used to simultaneously analyze these marker components of three natural product complexes (Mix) and to validate the analytical method through experiments such as linearity, accuracy and precision. The detection wavelengths were set at 210, 265, and 330 nm. The detected 3 compounds from extract of CZ, PF, RM showed significant linearity ($R^2${\geq_-}$0.9947). The limit of detection (LOD) of chlorogenic acid, astragalin and rosmarinic acid were $8.29{\mu}g/ml$, $2.28{\mu}g/ml$, and $27.00{\mu}g/ml$, respectively. The limit of quantification (LOQ) of chlorogenic acid, astragalin and rosmarinic acid were $25.11{\mu}g/ml$, $6.92{\mu}g/ml$, and $81.83{\mu}g/ml$, respectively. The contents of the three indicators of Mix were 19.82-24.71 mg/g of chlorogenic acid, 43.80-46.02 mg/g of astragalin, and 46.33-48.57 mg/g of rosmarinic acid.

Obesity is a major risk factor for various metabolic diseases such as cardiovascular disease, hypertension, and type 2 diabetes mellitus. In this study, we prepared ethanol extracts from Agastache rugosa (ARE), Chrysanthemum zawadskii (CZE), Mentha arvensis (MAE), Perilla frutescens (PFE), Leonurus sibiricus (LSE), Gardenia jasminoides (GJE), and Lycopus coreanus (LCE). The anti-oxidant and anti-adipogenic effects were evaluated. The $IC_{50}$ values for ascorbic acid and LCE against 2,2-diphenyl-1-picrylhydrazyl radicals were $246.2{\mu}g/mL$ and $166.2{\mu}g/mL$, respectively, followed by ARE ($186.6{\mu}g/mL$), CZE ($198.6{\mu}g/mL$), MAE ($337.1{\mu}g/mL$), PFE ($415.3{\mu}g/mL$), LSE ($548.2{\mu}g/mL$), and GJE ($626.3{\mu}g/mL$). In non-toxic concentration ranges, CZE had a strong inhibitory effect against 3T3-L1 adipogenes (84.5%) than those of the other extracts. Furthermore, the anti-adipogenic effect of CZE is largely limited in the early stage of adipogenesis, and we revealed that the inhibitory role of CZE in adipogenesis is required for the activation of Wnt signaling. Our results provide scientific evidence that the anti-adipogenic effect of CZE can be applied as an ingredient for the development of functional foods and nutri-cosmetics for obesity prevention.

This study investigated the plant growth promoting activity of geraniol on Chinese cabbage (Brasscia campestris ssp. Pekinensis Rupr.), Pak Choi (Brassica rapa L.), Crown daisy (Chrysanthemum coronarium L.), Iceberg lettuce (Lactuca sativa L.) and Leaf perilla (Perilla frutescens Britt.). Geraniol at 0.5 to $10mg\;L^{-1}$ promoted radical growth of Chinese cabbage Pak Choi, Crown daisy, Iceberg lettuce and leaf perilla by >30%. In the pot experiments, geraniol treatment at $20mg\;L^{-1}$ by drenching increased up to 190% of the aerial part growth promotion. By comparison, foliar application showed 124% promoting activity only at $100mg\;L^{-1}$.

Many studies have been widely carried out to find out new compound having anti-cancer activity from animals and plants. Some plants have been reported to have anti-lancer effects. However, the anti-cancer effect of edible plants were seldomly evaluated. Therefore we investigated the anticancer effects of edible plants (10 samples) easily available around us by measuring number of survival cancer cells after treatment with direct cell counting and MTT analysis, and by examining the morphological change under the electromicroscope. Of the 10 samples tested, Equisetum arvense L., Lactuca dentata Mokino. var. faviflora Makino. showed moderate anti-cancer effects even at the concentration of 10 $\mul/ml$ against MCF-7 adenocarcinoma cell line. Of them, Capsicum annuum L. had most potent anti-cancer activity against MCF-7 adenocarcinoma cell line showing proliferation inhibited, morphological change and apoptosis at the concentration of 2 $\mul/ml$.
