애기똥풀(Chelidonium majus L. subsp. asiaticum H.Hara)의 지상부는 백굴채라고 불리며 항암, 항균 등의 효능을 가지고 있어 예로부터 약용으로 이용되었다. 그러나 천연 약용소재로 개발가치가 높음에도 불구하고 실생묘의 대량 확보를 위한 종자번식 관련 연구가 전무한 실정이다. 본 연구에서는 애기똥풀의 발아 및 휴면 특성을 분석함으로써 추후 종자번식을 위한 기초자료를 제공하기 위해 수행되었다. 실험재료로 사용된 애기똥풀 종자는 2019년 6월 경상북도 봉화군에서 채종하였으며 정선 후 건조상태로 실온(25℃)에 보관하였다. 종자의 1000립중은 0.57±0.01g이며, 배종비는 0.21±0.12로 조사되어 형태적으로 미성숙한 배를 가지고 있다. 종자의 활력은 테트라졸륨 검정을 통해 79%로 확인되었다. 종자의 기본 함수율은 7.64±0.25%였으며, 침지 2일 차에 최대함수율(32.6±0.34%)에 도달하였다. 초기 발아검정은 25/15℃ (light/dark, 16/8h)챔버에서 명조건과 암조건으로 구분하여 30일간 진행하였으며, 암조건은 알루미늄 호일로 광을 완전히 차단하고 최종 발아율만 조사하였다. 발아율을 조사한 결과, 명조건은 0.75±0.80%, 암조건은 5.50±1.55%로 조사되어 형태적인 휴면과 생리적인 휴면을 모두 갖는 것으로 판단하였다. 애기똥풀의 생태적인 환경을 고려하여 12주의 Summer temperature(S12, 25/15℃, 16/8h)로 층적하고 연속하여 Autumn temperature(A, 15/10℃, 16/8h)를 4주(A4)와 8주(A8)로 달리하여 종자의 휴면타파를 유도하였다. 층적 후 발아율은 모두 증가되었으며, S12-A4(54%)는 S12-A8(24.5%)에 비해서 휴면타파에 효과적이었다. 휴면타파 효과의 증진을 위해 층적처리한 종자를 500ppm의 GA₃와 GA₄₊₇에 각 24시간동안 4℃에서 침지시킨 뒤 동일한 조건에 파종하였다. GA₃가 처리된 S12-A4는 발아율이 82.0%, S12-A8는 30.8%로 유의적으로 증가하였으나 GA₄₊₇ 처리는 S12-A4(48.5%)와 S12-A8(21.3%)에서 발아율 향상 효과가 없었다. 결론적으로 애기똥풀의 휴면타파를 위해서 12주의 Summer temperature와 4주의 Autumn temperature 변온층적과 추가 GA₃ 처리가 휴면타파를 위한 효과적인 처리방법으로 판단된다.

The Purpose or this study was to determine the optimal dyeing condition or Chelidonium majus extracts onto silk fabrics. Among the various dyeing properties, the colorfastness of fabrics dyed with Chelidonium majus extracts was investigated in different conditions such as dyeing temperature, dyeing time, dyeing pH etc. We also tried to dye fabrics using the Chelidonium majus extracts which were lyophilized. Although mordant was not used, dyed fabrics showed relatively good dyeability and the main pigment of Chelidonium majus showed yellow vividly in the appropriate dyeing conditions. At a dyeing temperature above 40$^{\circ}C$, the $\Delta$E value increased but the yellowish tint decreased. The pH value of unadjusted Chelidonium majus extracts was 6.4, at which a deep yellow was obtained. The dye equilibrium was reached 40 minutes after dyeing. The colorfastness to washing and light was poor at 1-2 and 2-3, respectively, but the dry-cleaning fastness was good at 4-5.

The purpose of this study is to examine the influence of the pigment characteristic and changes in dying conditions on the dying properties by extracting Chelidonium majus var. asiaticum using distilled water and ethanol as solvents. Changes in dying conditions include variations in dye concentrations, dyeing temperatures and time on dye uptake, and K/S Value was compared according to these changes. Additionally, color changes were observed through mordant. Ultraviolet-visible spectrum was used to investigate the pigment characteristic, and as a result, tannin was identified in distilled-water-extract, whereas berberine and chlorophyll were identified in ethanol-extract. In FT-IR analysis, tannin in distilled-water-extract was verified as hydrolyzable tannin. For ethanol extract, chlorophyll was verified through absorption band of C-H, which is aliphatic spectrum around $2920cm^{-1}$ and $2850cm^{-1}$. From GC/MS analysis, oil components as well as terpine compounds were detected in ethanol-extract, and this, in turn, brings expectation regarding functionality. When dying in silk, dye uptake increased as concentration of the extract increased, and the optimum dyeing temperature and time were $40^{\circ}C$ and 60 minutes respectively. Dyed fabrics' colors were all basically Y-series colors, and adjustment in brightness and revelation of khaki color were also available depending on the type of the mordant. Color fastness, except for washing fastness, was good in silk dyed with distilled-water-extract. Thus, it can be concluded that by selecting the right extracting method and by doing proper dyeing and mordant according to the needs, these dyed fabrics can be used as eco-friendly, functional clothing material.

The main colorant of Chelidonium majus extracts is a berberine which shows relatively good dyeability onto silk fabrics in the appropriate dyeing conditions without mordant, But cotton fabrics are difficult to dye with berberine because of the low substantivity the cationic to cellulosic fibers. we treated cotton fabrics using three types of polycarboxylic acid, DL-malic acid, citric acid, 1,2,3,4-butanetetracarboxylic acid(BTCA) to increase dyeability of Chelidonium majus extracts onto cotton fabrics. As a result the cotton fabrics treated with polycarboxylic acid could be dyed with Chelidonium majus extracts and also showed yellow vividly. The dye uptake were increased with increasing the number of carboxy groups. And so dye uptake resulted the largest in the BTCA solutions which have four carboxylic groups in the molecular unit. The optimal dyeing temperature a of Chelidonium majus extracts onto polycarboxylic acid treated cotton fabrics were $60^{\circ}C$. The dye equilibrium was reached 20 minutes after dyeing. Neutral pH of dye solutions showed in higher K/S value than acidic or alkaline conditions. But the colorfastness to washing and light according to polycarboxylic acid treat was not enhance.

The aim of this study was to evaluate the cytotoxicity of cadmium chloride ($CdCl_2$), toxicant, and the protective effect of Chelidonium majus (CM) extract on $CdCl_2$-induced cytotoxicity in cultured NIH3T3 fibroblasts. Cell viability, the effect of butylated hydroxytoluene (BHT) against $CdCl_2$, and the antioxidative effects including DPPH-free radical scavenging activity, superoxide anion-radical scavenging activity (SSA), and lactate dehydrogenase (LDH) activity were assessed. $CdCl_2$ caused a significant dose-dependent decrease in cell viability, and $XTT_{50}$ value was determined at 38.7uM of $CdCl_2$. It was determined as highly-toxic by Borenfreund and Puerner' toxic criteria. BHT of antioxidant significantly increased cell viability severely damaged by $CdCl_2$-induced cytotoxicity in these cultures. In the protective effect of CM extract on $CdCl_2$-induced cytotoxicity, CM extract significantly increased cell viability, DPPH-free radical scavenging activity, SSA and inhibitory activity of LDH. From these results, it is suggested that oxidative stress is involved in the cytotoxicity of $CdCl_2$, and CM extract showed protective efficacy on $CdCl_2$-induced cytotoxicity via antioxidative effects. Conclusively, natural resources like CM extract may be a putative antioxidative agent for the detoxification or diminution of toxicity correlated with oxidative stress.

This study focused on the usefulness of plant extracts for a city organic farm. Insecticidal activity of 8 plant species, plants crude extracts by ethanol and water, against third instar larvae (susceptible strain) of Plutella xylostella was evaluated in this study. Ethanol(25%) extracts of plant materials had better insecticidal activity than water extracts at the room temperature. Insecticidal activity were investigated by leaf disc spray method. Five plant extracts (Capsicum annuum, Chelidoniun majus, Leonurus sibiricus, Coptis japonica, Mentha piperascens) showed over 50% insecticidal activity to P. xylostella at the concentration of $1500mg{\cdot}L^{-1}$. Extract of C. annuum showed the highest insecticidal activity (83.3%) against P. xylostella. Phytotoxicity was not observed on Raphanus sativus and Brassica campestris with spray application. Seed germination and growth of two plants were not affected. Extract of C. japonica revealed 73.3% control efficacy against P. xylostella of R. sativus and showed 70% control efficacy against those of B. campestris, respectively, in plastic house. Insecticidal activity against various insects was observed in C. japonica extract as 87.4% for R. sativus and 74.3% for B. campestris in the field. These results suggested that extracts of C. annuum, C. japonica showed the highest insecticidal activity, and could be used as city farm insecticides for organic farming.
