Background: This study was conducted to investigate the effects of fertilization with the application of mixed organic matter after cultivating green manure crops on the growth and saponin content of Codonopsis lanceolata Trautv.
Methods and Results: Five type of cultivation of green manure crops were done: hairy vetch as a single seedling crop (HV), hairy vetch and rye as a mixture of seedling (HV/R), additional fertilization with mixed organic matter after cultivation of a seedling mixture (HV/R/MO), chemical fertilizer (CF), and a non-treated control (NT). The total nitrogen content was the highest in the HV/R/ MO treatment, followed by the HV, CF, HV/R and NT treatments, respectively. Nitrogen fixation was higher in the single seedling treatment with hairy vetch (HV) than in the treatment with a mixture of hairy vetch and rye seedling (HV/R). Moreover, the growth of C. lanceolata was greatly increased by the application of additional fertilizer after treatment with the mixture of hairy vetch and rye seedlings. The HV/R/MO treatment produced the highest total lancemaside content among the treatments, followed by HV, HV/ R, CF, and NT, respectively.
Conclusions: It was verified that C. lanceolata experienced superior growth with the application of mixed organic matter as additional fertilizer after the cultivation of green manure crops, and the content of its major saponins, lancemasides were also increased by this treatment.

Background: Various Schisandra chinensis (SC) varieties grow in diverse regions in Korea. However, there is no valid scientific evidence of these varieties. This study aimed to select the excellent resources in terms of the growth characteristics, antioxidant activities, and analysis of the active compounds of the SC collection.
Method and Results: In total, 154 resources of SC were collected from various regions of Korea. The growth characteristics were measured by the number of fruit bunches, fruit number, and weight of 100 fruits. The antioxidant activities were investigated by analyzing the total flavonoid and total polyphenol contents and the radical scavenging activity of DPPH and ABTS. Schizandrin A, schizandrin c, gomisin a, and gomisin N were analyzed by HPLC. Each resource showed different growth characteristics. Among the antioxidative effects, the highest 20 resources showed high antioxidant activities in selected 29 resources. Analysis of the SC lignan index showed that all resources contained more than 1.16% of active compounds.
Conclusions: All of the selected 29 SC resources were shown to have excellent growth characteristics, antioxidant activities, and bioactive compound richness. Especially, SC-004, SC-007, and SC-154 showed the best growth characteristics, and SC-22, SC-40, and SC-45 showed the best antioxidant activities and bioactive compound richness.

Background: Cnidium officinale Makino and Ligusticum chuanxiong Hort. are important medicinal crops in Korea. However, there is insufficient information on the identification of thrips, which attack these plants. Until now, one species of thrips has been recorded as a main pest.
Methods and Results: To identify the thrips emerging in C. officinale Makino and L. chuanxiong Hort., these plants were independently cultivated in two local areas. Thirty individuals of each plant species were selected randomly and surveyed for the presence of thrips. After confirming the existence of thrips, 100 thrips individuals were collected from each crop using the beating method. To identify thrips species, we performed PCR-restriction fragment length polymorphism (RFLP)-based analysis using ITS2 primer sets. Six thrips species were identified: western flower thrips (Frankliniella occidentalis), flower thrips (F. intonsa), onion thrips (Thrips tabaci), chrysanthemum thrips (T. nigropilosus), chilli thrips (Scirtothrips dorsalis), and grass thrips (Anaphothrips obscurus). The proportion of these species differed between the host plant species.
Conclusions: Six thrips species were major pests of two medicinal crops. Integrated pest management is required to control these thrips species, and will enhance the yield and quality of C. officinale and L. chuanxiong.

Background: Camellia sinensis L.(CS) is a perennial evergreen species of plant whose leaves are used to produce tea. In this plant species, the parts used are the leaves, sub-branch parts are thrown out.
Methods and Results: Ethanol extract of sub-branch parts was used for isolation of major compounds by column chromatography. Structures were identified as caffeine (1), (-)-epicatechin (2) and (-)-epicatechin gallate (3) by interpretation of spectroscopic analysis, including 1H- and 13C-NMR. High-performance liquid chromatography (HPLC) method was used to compare the quantitative level of marker compounds in various extraction solvents of sub-branch parts of CS. The content of caffeine, (-)-epicatechin, and (-)- epicatechin gallate in 30% ethanol extract showed higher value with 3.28 ± 0.57 ㎎/g, 5.53 ± 0.88 ㎎/g, and 1.29 ± 0.24 ㎎/g, respectively.
Conclusions: These results indicated that not only leaves parts but also sub-branch, could be a good source for the functional material and pharmaceutical industry.

Background: This study was conducted to investigate the changes in the photosynthetic parameters, chlorophyll content, chlorophyll fluorescence, and growth characteristics of Aruncus dioicus var. kamtschaticus seedlings under different shading treatments. Methods and Results: The shading treatment was regulated with the shading level (non-shaded, 35%, 55%, and 75% shading). Photosynthetic activities, such as net photosynthetic rate, stomatal conductance, stomatal transpiration rate, and performance index on absorption basis (PIABS)were the highest under 35% shading (4.36 μ㏖ CO2·m−2·s−1, 54.2 m㏖ H2O·m2·s−1, 0.66 m㏖ H2O·m−2·s−1, and 1.3, respectively), and the lowest under 75% shading. This implies that the decrease in net photosynthetic rate may be due to an inability to regulate water and CO2 exchanged through the stomata. Thechlorophylla, b, and a + b contents were increased with elevating shading level and the chlorophyll a/b ratio showed non-significant differences. It was found that the dry weight (leaf, shoot, and whole) was the highest (1.14 g, 0.49 g, and 2.31 g, respectively) under 35% shading and the t/R ratio was the highest under 75% shading.
Conclusions: It is concluded that 75% shading exhibited a strong reduction of photosynthetic activity, and 35% shading showed the best conditions for the early growth and cultivation of A. dioicus var. kamtschaticus.

Background: Taraxacum platycarpum has been used in traditional medicine in Korea to treat intoxication and edema and as a diuretic. According to previous reports, it has anti-cancer, anti-gastritis, and anti-inflammation effects. However, the improvement effect of T. platycarpum on rheumatoid arthritis has not been investigated. The anti-oxidative and anti-inflammation effects of the aerial parts of T. platycarpum are different from those of its subterranean parts. Thus, we evaluated the effect of the water extracts of Taraxaci radix (WTR) on type II collagen-induced rheumatoid arthritis (CIA) in animal models.
Methods and Results: Rheumatoid arthritis was induced by type II collagen. WTR (100㎎/㎏ and 500㎎/㎏) was administered to the animal models. Methotrexate was used as the positive control. The levels of interleukin-6, TNF-alpha, and type II collagen IgG in the animals were measured by using enzyme-linked immunosorbent assay. Treatment with 500㎎/㎏ WTR decreased the serum levels of interleukin-6, TNF-alpha, and collagen IgG in the CIA models. Moreover, treatment with WTR diminished the arthritisinduced swelling of the hind legs and monocyte infiltration in the bloodvessels of the animal models.
Conclusions: These results indicate that WTR has the potential to improve rheumatoid arthritis by reducing the levels of inflammatory cytokines such as interleukin-6 and TNF-alpha. However, further experiments are required to elucidate the influence of WTR on signal transduction in vitro and in vivo.
