In order to investigate the quality characteristics of candies prepared with Compositae species flower extracts, the samples of Chrysanthemum indicum Linne (CI), C. boreale Makino (CB), and C. zawadskii var. latilobum (Maxim.) Kitam (CZ) were extracted with hot water and concentrated, and then added with various concentrations of 5$\sim$20% for candy preparation. L-value of candy color was decreased, but a- and b-value were increased with increasing amount of added extracts. pH was decreased, but total acidity was increased with increasing amount of added extracts. Moisture content of CI, CB, and CZ candies were 2.61$\sim$4.11, 2.46$\sim$4.57, and 2.27$\sim$4.43%, respectively. Hardness of candies were decreased with increasing amount of added extracts. CZ candy of 20% added extract showed the highest total polyphenol, flavonoid content, electron donating ability and anol, flavonaid content at 2.71 mg/g, 0.86 mg/g, 76.24%, and 3.17 mg AA eq/g, respectively. In sensory evaluation, the CI and CZ candies of 10% added extract obtained higher sensory scores.

Objectives : The objective of present study was to investigate the vasorelaxant effects of 20 Korean native plants on isolated rat thoracic aorta precontracted with phenylephrine (PE). Methods : Dried 20 plant materials were extracted 3 times with water, ethanol, or methanol for 3h in the reflux apparatus at 70 ± 5℃. Male SD rats were anesthetized by ether inhalation, and their aorta rings were isolated and placed in 10 ㎖ Krebs Henseleit (KH) buffer. While using an isolated organ-chamber technique, the aorta rings were maintained by bubbling with a gas mixture of 95% O₂-5% CO₂ at 37℃. Changes in isometric tension of aorta rings were recorded via isometric transducers connected to a Powerlab Data Acquisition System. Results : Among the 20 native plants, Chrysanthemum indicum L. flower, Nelumbo nucifera Gaertn. rhizome, Schisandra chinensis (Turcz.) Baill. fruit, Anthriscus sylvestris (L.) Hoffm. root, Corydalis turtschaninovii Besser tuber, Corydalis decumbens (Thunb.) Pers. tuber, and Dolichos lablab L. seed showed significant vasorelaxant effect on the contraction of aorta rings induced by PE. In contrast, Mertensia maritima subsp. asiatica Takeda whole plant, Ajuga decumbens Thunb. whole plant, Trigonotis peduncularis (Trevis.) Benth. ex Baker & S.Moore whole plant, Dioscorea quinquelobate Thunb. rhizome, Allium microdictyon Prokh aerial part, Momordica charantia L. fruit, Carthamus tinctorius L. flower, and Clematis terniflora DC. root constricted more the aorta rings precontracted by PE Conclusion : These results suggest that the possibility as useful herbal resources for the development of functional foods or medicines for hypertension treatment.

This study was carried out to investigate the effects of uniconazole treatment on the growth and flowering of potted Chrysanthemum indicum L. for high quality pot plant production. Uniconazole was drenched at 0.05, 0.01, or 0.15 mg a.i./pot at 14 days after planting (DAP) of rooted cuttings. Simultaneously the short-day treatment (SDT) and pinching were adapted. The same amount of uniconazole (0.05 mg a.i./pot) was spilt drenched at once, twice, and three times, respectively, at 1 week interval. Uniconazole markedly reduced plant height, branch length, and stem diameter. Plant height was reduced linearly with increasing uniconazole concentration at 0.05, 0.01, or 0.15 mg a.i./pot up-to 41.6%, 52.5%, and 58.5%, respectively. In 0.05 mg a.i./pot, the number of branches greatly increased and plant height of 22.6 cm was adequate for pot plant. However, higher concentrations (0.10, 0.15 mg a.i.) were not suitable for production of high quality pot plant (17.0, 14.8 cm, respectively). Pinching and SDT decreased the number of days to visible bud, while uniconazole treatments delayed days to visible bud by 5-9 days compared with pinching and SDT. Number of visible buds was highest at 0.05 mg a.i./pot uniconazole treatment. However, flower diameter was decreased by uniconazole treatment, resulting in compact form. Number of stomata was increased by uniconazole treatment. The length of vascular tissues of uniconazole-treated plants ($11.2{\mu}m$) was smaller than that of non-treated plants ($15.0{\mu}m$, and the size of xylem vessel was also decreased. Uniconazole treatment at 0.05 mg a.i./pot at 14 DAP with pinching and SDT were recommended for pot plant production of C. indicum L.

Seven native and four introduced herbs namely $Thymus$ $quinquecostatus$, $Chrysanthemum$ $zawadskii$ var. $latilobum$, $Rosmarinus$ $officinalis$, etc. were selected for analysis of the DPPH radical scavenging and anti-microbial activity of their extracts. These perennial herbs are classified as $Labiatae$ and $Compositae$ except for $Saururus$ $chinensis$ and can be propagated through seedling and cuttage. These edible herbs are used as medicinal as well as ornamental plants. Their extract has electron donating ability which ranges from 69.7 to 78.7% for native herbs and 67.4 to 75.4% for introduced herbs. Native herbs have higher (3.54%) average DPPH radical scavenging than introduced herbs. In native herbs, maximum DPPH radical scavenging activity was observed in $Agastache$ $rugosa$ (78.7%) followed by $Saururus$ $chinensis$ while $Chamaemelum$ $nobile$ showed highest activity among the introduced herbs. Many herbs viz. $Saururus$ $chinensis$, $Chrysanthemum$ $zawadskii$ var. $latilobum$ and $Solidago$ $virga-aurea$ var. $gigantean$ showed excellent anti-microbial activity against gram positive $Enterococcus$ $faecalis$, maximum (80.0%) by $Saururus$ $chinensis$. Other herbs viz. $Solidago$ $virga-aurea$ var. $gigantea$, $Chrysanthemum$ $zawadskii$ var. $latilobum$, $Salvia$Salvia $plebeia$, $Chrysanthemum$ $indicum$, $Rosmarinus$ $officinalis$, $Chamaemelum$ $nobile$ and $Lavandula$ $stoechas$ showed anti-microbial activity against gram negative $Citrobacter$ $freundii$. Especially, the inhibition of colony growth of $Citrobacter$ $freundii$ was highest in the extract of $Chrysanthemum$ $zawadskii$ var. $latilobum$, and $Chamaemelum$ $nobile$.

The antioxidant activities of ethanolic extracts obtained from medicinal plants (Scutellaria baicalensis Georgi, Acanthopanax sessiliflorum Seeman, Pueraria lobata Ohwi, Portulaca oleracea Linne, Crataegus pinnatifida Bunge var. typica Schneider, Euonymus alatus Apterus, Hovenia dulcis Thunberg, Prunus yedoensis Matsumura, Albizzia julibrissin Durazz., Chrysanthemum indicum Linne) were evaluated for total phenolic content, total flavonoid content, DPPH radicals, nitrites, $Superoxide^-$ radicals, $ABTS^+$ radical scavenging activity, and reducing power. Antioxidant capacities were the highest in Prunus yedoensis Matsumura for DPPH radical scavenging activity ($IC_{50}$ $5.39{\mu}g/mL$), reducing power (2.72, $A_{700}$), and nitrite scavenging activity ($IC_{50}$ $167.94{\mu}g/mL$). Hovenia dulcis Thunberg and Acanthopanax sessiliflorum Seeman were effective for their nitrite scavenging activities (over 90% at 1 mg/mL). The $Superoxide^-$ radical scavenging activity of Prunus yedoensis Matsumura ($IC_{50}$ $43.39{\mu}g/mL$) was stronger than tannic acid ($IC_{50}$ $46.51{\mu}g/mL$). Five samples (Prunus yedoensis Matsumura, Acanthopanax sessiliflorum Seeman, Hovenia dulcis Thunberg, Crataegus pinnatifida Bunge var. typica Schneider, Scutellaria baicalensis Georgi) were effective for their $ABTS^+$ radical scavenging activity (more than 90% at 0.5 mg/mL). These results suggest that the ethanolic extracts of Prunus yedoensis Matsumura could be used as a functional ingredient in food products.

Volatile compounds of dropwort (Oenanthe javanica DC), crown daisy (Chrysanthemum coronarium L. var. spatiosum), and sesame (Sesamum indicum L.) were isolated by steam distillation under reduced pressure (DRP) and liquid-liquid continuous extraction (LLE). Aroma extracts of the plants were identified by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) and their antioxidant activities were evaluated in two different assays. The aroma extracts isolated from dropwort, crown daisy, and sesame inhibited the oxidation of hexanal by 25%, 95%, and 99%, respectively, for one month at the $500{\mu}g/mL$ level. They inhibited malonaldehyde formation from cod liver oil by 48%, 54%, and 29%, respectively, at the $500{\mu}g/mL$ level. Their antioxidant activities were comparable to those of the natural antioxidant, ${\alpha}-tocopherol$.

In this study, we investigated whether cynaroside, cynarin and linarin derived from Chrysanthemum indicum L. affect the secretion, production and gene expression of MUC5AC mucin in airway epithelial cells. Confluent NCI-H292 cells were pretreated with cynaroside, cynarin or linarin for 30 min and then stimulated with PMA (phorbol 12-myristate 13-acetate) for 24 h. The MUC5AC mucin gene expression, mucin protein production and secretion were measured by RT-PCR and ELISA, respectively. Effect of linarin on EGF (epidermal growth factor) - or TNF-${\alpha}$ (tumor necrosis factor-${\alpha}$)-induced MUC5AC mucin gene expression and mucin protein production was also examined. The results were as follows: (1) Cynaroside and cynarin did not significantly affect PMA-induced MUC5AC mucin secretion from NCI-H292 cells. However, linarin decreased MUC5AC mucin secretion; (2) Cynaroside did not affect PMA-induced MUC5AC mucin production and gene expresion from NCI-H292 cells. However, cynarin and linarin inhibited the production and gene expression of MUC5AC mucin; (3) Linarin also inhibited the production and gene expression of MUC5AC mucin induced by EGF- or TNF-${\alpha}$ from NCI-H292 cells. These results suggest that linarin can regulate the gene expression, production and secretion of mucin, by directly acting on airway epithelial cells.

Objective : In this study, herbal medicine(GJE, Gardenia jasminoides Ellis; HCT, Houttuynia cordata Thunb.; CIL, Chrysanthemum indicum Linne; PMS,Paeonia moutan Sims, P. subfruticosa Makino; APL, Agrimonia pilosa Ledebour) were screened for their inhibitory activities against Tyrosinase and PMA plus A23187-induced $TNF-{\alpha}$, IL-6, IL-8 productions in HMC-1 cells to reveal their skin -whitening and anti-allergic effect. Method : To investigate Tyrosinase inhibition we treated Mushroom Tyrosinase(Fluka, 93898) $10{\mu}{\ell}$ and 7.5mM Tyrosine (Sigma, T3754) $20{\mu}{\ell}$ with 80% ethanol medicine extracts. Then we observed 96well micro plate extinction at 490nm. In the next experiment, to investigate Anti-allergic effect we blended cultured Human Mast Cells(HMC-1) with medicine extracts. We treated the blended solution with Phorbol 12-myristate 13-acetate(PMA) and A23187, then observed $TNF-{\alpha}$, IL-6, IL-8 by ELISA (enzyme-linked immunosorbent assay) at 450nm. Results : In inhibiting Tyrosinase the results are as follows. 1. We observed 22% inhibition of Mushroom Tyrosinase at $500{\mu}g/m{\ell}$ concentration of GJE extracts. 2. We also could observe that the decreased Mushroom Tyrosinase activities in HCT, CIL extracts. In inhibiing $TNF-{\alpha}$, IL-6, IL-8 productions in HMC-1 cells the results are as follows. 1. Of the extracts examined, HCT, PMS, APL extracts showed over 50% inhibitions of Cytokines at $200{\mu}g/m{\ell}$ concentration. 2. In particular, APL extracts showed the best inhibitory effect on Cytokine productions in a dose-dependent manner. Conclusion : These results suggest that GJE extracts contributes to the anti melanin activities and represent a potential source of whitening agent. Thus these herbal medicines suggest novel drugs on anti-allergic effects.
