  • To investigate bioactive materials for development of natural conservative agent on organic cultural heritage, methanol extracts from 17 medicinal plants were screened for antifungal and insecticidal activity against 6 wood rot fungi and adult of Lasioderma serricorne. Antifungal activity of extracts was tested by using paper disc soaking method against wood-rot fungi. Among these extracts, the most significant antimicrobial activity was observed from the extract of Coptis japonica at 5 mg/disc against all wood rot fungi tested. The insecticidal activity of extracts was examined by topical application against L. serricorne adults. The extracts from Asarum sieboldii gave 83.3 % mortality at $25{\mu}g/adult$ for 24hr. From these result, the methanol extract from C. japonica and A. sieboldii described could be useful for conservation of organic cultural heritage against biological deterioration by wood rot fungi and L. serricorne.

  • This experiment was carried out to investigate the effects of shading treatments and harvesting methods on the growth of Eleutherococcus senticosus, which was known as the medicine of anticancer, anti-stress, hepatic detoxification activity, immunoactivity, and tonic. Light transmission ratio and air temperature were decreased as $40{\sim}64%$,$1.9{\sim}2^{\circ}C$, respectively, in 30% to 70% shading net treatment compared to non-shading. Fifty percentage shading net treatment was effective for the growth and yield of Eleutherococcus senticosus. During summer Eleutherococcus senticosus was growing under shading net treatment compared to non-shading. Tunnel type was more effective for growth than vertical type in shading method. 30cm length included 2 to 3 nodes cutting from soil surface was the most effective for branching stem length, plant height and yield as harvesting methods.

  • The genus Hemerocallis (family Xanthorthoeaceae) is a herbaceous species, some of which are very important in herbal medicines. We evaluated the rps16-trnK region of the chloroplast DNA of a representative sample of eight taxa in Korea to estimate phylogenetic relationships within the taxa of this genus. Due to differences in the number of inserted nucleotides, the aligned data for Hemerocallis ranged from 729 (H. aurantiaca) to 742 nucleotides (H. fulva var. kwanso), with a mean of 736. Although several small indels and 20 inserts were present, sequence variation within the Hemerocallis genus was mostly due to nucleotide substitutions. All rps16-trnK trees generated in Korea exhibited a well-solved topology, with high bootstrap support, irrespective of the methods (parsimony) and the setting used. The node of H. minor and H. littorea was strongly supported, with a high bootstrap value in three trees, and these two taxa were sistered with H. thunbergii. The number of chromosomes was not congruent with that found in a previous study with RAPD, but the number was in agreement with the results of this study.

  • The succulent herbaceous perennial Sedum sarmentosum commonly grows in the southern part of the Korean Peninsula. It is a species native to China, most likely introduced into Korea due to its edible and medicinal uses. If plants were introduced from a single source, we would expect no or low levels of genetic variation in Korean populations. Alternatively, if plants were introduced from multiple sources, we would expect, in contrast, high levels of genetic diversity. To test which is more likely, we surveyed the degree of allozyme variation in ten populations of this species from southern Korea. We found that S. sarmentosum was monomorphic at all fifteen allozyme loci. However, two congeners (S. polytrichoides and S. kamtschaticum) and two related species (Hylotelephium ussuriense and H. verticillatum) maintain moderate to high levels of genetic diversity ($H_e=0.144$, 0.203, 0.201, and 0.204, respectively). We suggest that southern Korean populations of S. sarmentosum likely descended from a single introduction of a few plants and then became naturalized exclusively via vegetative spreading (as plants in Korea, but also as occurs in other parts of its native and naturalized range, are sterile).

  • 현삼과(Scrophulariaceae)의 둥근산꼬리풀(Veronica rotunda Nakai)은 흰색의 꽃이 총상화서로 피며, 관상용으로 쓰인다. 또한, 접선골도라 하여, 전초를 약용하고 활혈, 지혈, 청폐열, 화간위에 효능이 있는 자생식물이다. 본 연구는 둥근산꼬리풀의 포트 재배방법 확립을 위하여 2018년 5월 15일에 파종하여 생산된 유묘를 7월 16일에 정식하여 10월 15일까지 약 14주 동안 수행하였다. 식재용기 실험은 비닐포트[3치($7{\times}7cm$), 4치($9{\times}8.5cm$)]와 플라스틱 화분[8호($7{\times}7cm$), 10호($9{\times}9cm$), 12호($10.5{\times}10.5cm$)]를 이용하였고, 토양 종류[중화 피트모스:펄라이트(3:1, 4:1), 마사토:중화 피트모스(2:1, 3:1)], 묘의 소질[파종 립수(1, 2, 4, 6립), 파종 용기(162, 200, 288구 트레이)] 등의 연구를 진행하였다. 대조구는 플라스틱 화분 10호에 원예상토를 충진하고 200구 트레이에 4립씩 파종하여 생산된 1셀을 정식하였다. 연구의 결과, 식재용기에 따른 둥근산꼬리풀의 생육은 플라스틱 12호 화분에서 가장 양호하였으며, 토양의 양이 많을수록 전반적인 생육이 증가하였다. 토양 종류별로는 원예상토에서 재배한 처리구에서 양호한 생육을 보였다. 중화 피트모스와 펄라이트 3:1 혼용토의 경우, 원예상토와 전반적인 생육에 큰 차이가 없어 이용가치가 있을 것으로 판단된다. 한편, 피트모스의 비율이 높은 4:1 혼용토에서는 비교적 생육이 억제되었으며, 잎이 황화되었다. 마사토와 중화 피트모스의 혼용토는 원예상토에 비해 왜화되는 결과를 보였으며, 측지수, 마디수, 엽수에는 큰 영향을 주지 않았다. 그러나 개화율을 감소시키는 결과를 보였다. 셀당 파종한 종자의 양을 달리하여 생산된 유묘를 정식하여 재배한 결과, 전반적인 생육은 1립 파종구에서 양호하였다. 한편, 파종량이 많을수록 초장, 절간장이 감소하며, 포트당 마디수, 측지수 및 개화율이 증가하여, 본 연구의 목표인 관상적 이용에 적합한 것으로 판단된다. 파종용기별 생산된 유묘이식 결과, 초기생육이 왕성할수록 후기생육도 우수하였다. 162구 생산묘 정식구는 다른 처리구보다 전반적으로 생육이 왕성하였으며, 다음으로 200구 순이었다. 파종용기에 따른 묘의 크기는 정식 후의 개화율에 유의적인 차이가 없었다. 따라서, 둥근산꼬리풀의 재배는 플라스틱 화분 12호에 원예상토를 충진하여 162구 트레이에 셀당 6립 파종하여 생산된 유묘를 정식하는 것이 분화용 재배에 효과적인 것으로 생각된다. 한편, 재배에 이용되는 토양의 종류에 따른 비율 및 개화촉진 등의 추가적인 연구가 필요하다.

  • Panax ginseng (Ginseng or Korean ginseng) is one of the most important medicinal herbs in the world. We made a high-quality whole genome sequence of P. ginseng using 'Chunpoong' cultivar, which is the first cultivar registered in Korea Seed and Variety Service (KSVS) with relatively similar genotypes and superior phenotypes, representing approximately 3 Gbp and 60,000 genes. Genome sequence analyses of P. ginseng and related speciesrevealed the origin of Korean ginseng and the ecological adaptation of 18 Panax species around the world. Korean ginseng and American ginseng (P. quinquefolius) are tetraploid species having 24 chromosome pairs, while the other 16 species are diploid species with 12 chromosome pairs. Panax and Aralia are the closest genera belonging to the Araliaceae family that diverged approximately 8 million years ago (MYA). All Panax species evolved as shade plants adapting to cool climates and low light conditions under the canopy of deep forests from Southeast Asia such as Vietnam to Northeast Asia such as Russia approximately 6 MYA. However, through recurrent ice ages and global warming, most diploid Panax species disappeared due to the freezing winter, while tetraploid P. ginseng may have appeared by allotetraploidization, which contributed to the adaptation to cold temperaturesin Northeast Asian countries including the Korea peninsula approximately 2 MYA. American ginseng evolved by the adaptation of P. ginseng in Northeast America after the intercontinental migration 1 MYA. Meanwhile, most of diploid Panax species survived in high-altitude mountains over 1,600 meters in Southeast Asia because they could not endure the hot temperature and freezing cold. The genome sequence provides good basisto unveil the origin and evolution of ginseng and also supports practical gene chips which is useful for breeding and the ginseng industry.

  • Background: Allergic diseases like such as atopic dermatitis, asthma, and rhinitis have recently increased both domestically and globally. The present study was undertaken to select candidates with anti-allergic activity from plant resources. Methods and Results: Fifty-six plant extracts at $20{\mu}g/m{\ell}$ were screened against ${\beta}$-hexosaminidase production and interleukin (IL)-4 release in degranulated rat basophilic leukemia (RBL)-2H3 cells. The anti-allergy activity of three plant extracts selected from the preliminary screening experiment, Polygonatum sibiricum F. Delaroche (root), Pyrus pytifolia var. culta (Makino) Nakai (leaf), and Rehmannia glutinosa (Gaertn.) Libosch. ex Steud (root) were measured at concentrations of $2-250{\mu}g/m{\ell}$ in three cell lines as RBL-2H3, HaCaT and Jurkcat T cells. The assay showed the root extract of R. glutinosa to have an inhibitory activity of 4.2% - 28.6% on ${\beta}$-hexosaminidase production from IgE-sensitized RBL-2H3 cells. Each extract of P. sibiricum and R. glutinosa reduced IL-4 release in IgE-sensitized RBL-2H3 cells, respectively. The leaf extract of P. pyrifolia var. culta showed a significantly potent suppressive effect of 10.2% - 74.7% on the mRNA expression of tumor necrosis factor (TNF)-${\alpha}$ in HaCaT cells sensitized with TNF-a and INF-g, and showed inhibitory effect of -8.6% - 90.9% on the mRNA expression of IL-2 in Jurkat T cells sensitized with PMA and A23187. Conclusions: The results showed that the root of R. glutinosa and leaf of P. pyrifolia var. culta could be useful candidates as antiallergy materials.

  • To determine optimal fermentation period of vegetables mixed with black sugar without innoculation of microorganisms, changes in chemical components, quality characteristics of the fermented broth and physiological functionality during the fermentation period were investigated, pH and $^{\circ}BX$ of the fermented broths were decreased gradually during the fermentation period. Except for radish, L and a color values of fermented broths were increased but b values were decreased during fermentation period. Viscosity of fermented broths of vegetables were decreased after 3 months of fermentation. ${\alpha}-Amylase$ activity in fermentation broth of brocolli, eggplant, cabbage, chicory, aralia, radish were increased to 460, 430, 180, 420, 560, 260 after six months fermentation period. In radish and tomato fermentation broth, invertase activity were increased to 200 and 460 units and cellulase activity were increased to 280 and 140 after six months fermentation period. The content of total phenolic compounds and electron donating ability were the highest after 2 to 4 months fermentation period and decreased thereafter. No significant level of tyrosinase inhibitory activity and SOD-like activity were observed. In the sensory evaluation test of aralia fermentation broth of droop, sweet and sour flavor and bitter, astringent taste were decreased during the fermentation period and droop tastes were highest in 3 months. In radish fermentation broth, radish flavor and pungent taste were decreased and sweet taste was increased during fermentation period. Acceptability in overall was the greatest after three months. Based on the results stated above, optimal fermentation period was appropriated 3 or 4 months.

  • Seeds of Acanthopanx plants need about 2 years to germinate after sowing even if full matured fruits were harvested. I leave a room for doubt that this phenomenon could be brought by the immatured embryo in seed. If it is true, stratification method for the seed propagation of Acanthopanax plants would be used more effectively to promote the growth of embryo in relatively short time. Before stratification, seeds were devided into two parts. One of them was treated for 24hrs in the concentration of $GA_3$ 100 ppm. After stratification of non-treated and treated seeds, seeds for microtechnique were taken on interval of one month for three months, and fixed in Farmer's solution. The seed sizes of Acanthopanax plants were in biggest order A. sessiliflorus, A. seoulense, A. chiisanensis, A. koreanum and A. sieboldianum. The dehiscence phenomenon of seed coat didn't show in most of the seeds that stratified, but A. koreanum only dehisced in seeds treated in $GA_3$ 100ppm. The embryos of the stratified seeds that treated in $GA_3$ showed nomal growth, complete cotyledons and procambium in hypocotyl in any species, but the non-treated seeds could not expect the germination after sowing due to poor growing of the embryo in all species. In view of the results so far achieved, it has taken long times from sowing to germinate because the seed of Acanthopanax plants has immatured embryo.
