In order to investigate whether antioxidant biomaterials inhibits IL-4 and/or IL-13 expression in vitro and in vivo, we carried out antioxidant assays by enzyme or cell-based assays with Helianthus annuus extract. Antioxidant assays include DPPH, FRAP, hydroxyl radical assays. Helianthus annuus extract exhibited SOD scavenging activity, and had different patterns by each solvent extracted reaction. DW extract inhibited oxidative stress by $H_2O_2$ that induced apoptosis. We measured $CD4^+$ cell and IL-/13 cytokine expression in a classical mouse animal model. The result show that Helianthus annuus extract showed strung inhibition of immune response in the lung. These result suggest that Helianthus annuus extract can reduce inflammation induced by n mouse asthma model.

Helianthus annuus L. has been reported with various pharmacological activities such as antibacterial, antidiabetic, and antioxidant effects. According to recent studies, H. annuus L. is known to contain components such as phenolic compounds, flavonoids, alkaloids, sesquiterpenoids, and lignans. The seeds of H. annuus L. have been reported to contain chlorogenic acid and di-O-caffeoylquinic acid as major components. However, studies on the main components and content of leaves of H. annuus L. are still incomplete. Therefore, in this study, the contents of four major components of H. annuus L. were evaluated by simultaneous quantitative analysis with high performance liquid chromatography (HPLC)-diode array detector (DAD). The isolated four compounds Caffeoylquinic acid(CQA), 3,4-dicaffeoylquinic acid(3,4-DCQA), 3,5-dicaffeoylquinic acid(3,5-DCQA) and 4,5-dicaffeoylquinic acid(4,5-DCQA) were shown in a large linearity with a correlation coefficient (R²) of 0.99. In addition, as a result of intra-inter day analysis of four major compounds by the analysis method of this study, the accuracy of 88.46% or more and less than 112.85% and excellent precision of less than 3% were shown, the content analysis showed CQA (0.383±0.018 mg/g), 3,4-DCQA (0.282±0.017 mg/g), 3,5-DCQA (1.109±0.068 mg/g), and 4,5-DCQA (0.673±0.020 mg/g).

This study was performed to evaluate the remediation efficiency by Helianthus annuus, Brassica juncea and Brassica campestris on the soil contaminated with nickel, zinc and lead, respectively. The growth rates fell down under 60% in the condition of over 700 mg/kg of zinc for Brassica campestris, 300 mg/kg of lead for Helianthus annuus, and 150 mg/kg of nickel for Brassica juncea on the basis of heavy metal concentration in the soil, because of its toxicity. Also, the hyperaccumulators showed the maximum heavy metal contents in their biomass after 90 days of cultivation. The accumulated heavy metal content per kilogram of hyperaccumulator was 0.65 mg of nickel in Brassica juncea, 0.14 mg of zinc in Brassica campestris, and 0.06 mg of lead in Helianthus annuus, respectively. Additionally, 73.2% of nickel accumulated in Brassica juncea and 95.1% of zinc accumulated in Brassica campestris were concentrated in the upper site of crop like stem and leaves. However, in the case of Helianthus annuus, 83.7% of lead was accumulated in the root.

The stem rot of sunflower (Helianthus annuus) occurred sporadically in the experimental field of Gyeongsangnam-do Agricultural Research and Extension Services, on September, 2009. The infected plants were wilted and water-soaked brown spots were formed on the stem, than infected stems were mostly died. White mycelial mats were spread over lesions, and then sclerotia were formed on stem and near soil line. The sclerotia were globoid in shape, 1~3 mm in size and white to brown in color. The optimum temperature for mycelial growth and sclerotia formation on PDA was $30^{\circ}C$ and the hyphal width was $4{\sim}8\;{\mu}m$. The typical clamp connections were observed in the hyphae of the pathogenic fungus. On the basis of mycological characteristics and pathogenicity to host plants, this fungus was identified as Sclerotium rolfsii. This is the first report on the stem rot of sunflower by S. rolfsii in Korea.

According to the customary, naming is done after the subject is in existence. But the name's Hae-ba-ra-gi(해바라기), 향일규(向日葵), 향일화(向日花))' has been used as an alias of Hibiscus manihot L.(닥풀) long before Helianthus annuus L.(sunflower) was brought in to Korea. And now the usage of the name has been conversed since them. Since the incorrect record of '葵藿' and '葵花'as '해바라기' in ${\ulcorner}$조선어사전(朝鮮語辭典)${\lrcorner}$(1920), the mistake has been carried on this must be corrected from now on. Incorrect record of hollyhock(蜀葵花) '해바라기' in ${\ulcorner}$몽유(蒙喩))${\lrcorner}$(1810) took a role in this incorrect trend.

Oxidant stress is a well-known pivotal parameter for the degenerative immune diseases including asthma, atopic dermatitis, and rhinitis. In order to screen for anti-asthma agents effectively, we first established the infrastructure of high throughput screening(HTS) for anti-oxidant agents from agricultural products and/or oriental medicine library extracted with water, methanol, dimethyl sulfoxide, ethyl acetate and juice, Using the screening system, we found that Chaenomelis langenariae, Rhus javanica L., Camellia sinensis, Helianthus annuus and Angelica utilis Makino had strong anti-oxidant activity. Moreover, Helianthus annuus, Rehmannia glutinosa Libo and Angelica utilis Makino have protection activities by treatment of an oxidant hydrogen peroxide. Together, these results suggest that screened agents could be potential agents against asthma, although the in vivo studies should be clearly tested.

To explore the preservation parameters of a prototype anti-inflammatory drink containing a Helianthus annuus seed extract, we first examined sweetness, pH and color changes, and temperature effects during preservation. Over 25 days, pH rose slightly from 3.50 to 3.65. Small color changes in L, a, and b values occurred on prolonged storage. Temperature most affected storage properties, which differed considerably at $10^{\circ}C$ and $40^{\circ}C$. Microbiological safety tests showed that the prototype drink was safe; neither general bacterial contamination nor Escherichia coli growth occurred. We concluded that the prototype drink was biologically and microbiologically safe on preservation.

This research was investigated to prepare basic data in a study on the copper tolerance of herbaceous plants through the growth rate and the elimination rate dependent on Cu concentration of 6 species; Commelina communis, Medicago sativa, Echinochloa frumentancea, Zea mays, Helianthus annuus and Abutilon avicennae, We examined the germination rate, root and shoot growth of seedling and fresh biomass of 6 species (Commelina communis, Medicago sativa, Echinochloa frumentancea, Zea mays, Helianthus annuus and Abutilon avicennae) painted to Cu contaminated soil (50, 100, 200, 300-CuCl₂/㎏) and control for 14 days. The germination rate of H. annuus, E. frumentancea and C. communis were not affected by Cu concentration. However, root and shoot growth of H. annuus was about 7% of control and the biomass was 35% of control at 300 ㎎-CuCl₂/㎏. E. frumentancea and C. communis that showed good growth rate at higher Cu contaminated soil (>200 -CuCl₂/㎏), were the most tolerant plant to Cu concentration. Especially, E. frumentancea eliminated over 30% of Cu in soil and the amount of Cu uptake increased with increasing Cu concentration; 1,020㎎ Cu per 1 ㎏ of soil at 300 ㎎-CuCl₂/㎏. From these results, we concluded that E. frumentancea would be used for phytoremediation.

A full-length cDNA encoding ribulose-1,5-bisphosphate carboxylase small subunit (rbcS) has been isolated and its nucleotide sequence determined from root in ginseng plant (Panax ginseng). The rbcS cDNA of ginseng is 790 nucleotides long and has an open reading frame of 549 bp with deduced amino acid of 183 residues (pI 8.37), 20.5 kDa. The deduced amino acid sequence of rbcS matched to the previously reported rbcS protein genes and showed a high similarity with the $78\%$ identity with rbcS of Helianthus annuus (CAA68490). In the phylogenetic analysis based on the amino acid residues, the ginseng rbcS was clustered with H. annuus (CAA68490), C. morifolium (AA025119) and L. sativa (Q40250).
