  • This study investigated the color change, enhancement of dye uptake, washing fastness, and light fastness of cotton and silk when dyed with Juniperus chinensis and Terminalia chebula (combination dyeing) using various methods. The dyeing methods were 1) dyeing Juniperus chinensis extract and Terminalia chebula Retzius extract sequentially (J-T), 2) dyeing Terminalia chebula Retzius extract and Juniperus chinensis extract sequentially (T-J), 3) dyeing Juniperus chinensis extract and Terminalia chebula Retzius extract simultaneously (J+T), and 4) dyeing Juniperus chinensis extract 4 times repeatedly and followed by a dyeing Terminalia chebula Retzius extract in sequence. In terms of increased dyeing uptake, combination dyeing (dyeing 2 times like method 1, 2, 3) had the same impact as the repeated dyeing (method 4). The color of J, T combination dyeing showed wide range of mixed YR series, Y series resulting from Terminalia chebula Retzius, and R series resulting from Juniperus chinensis. In cotton, J-T dyeing method showed superior enhancement of dye uptake, and T-J method in silk. In both of the cases, Y series color from Terminalia chebula Retzius extract was mainly shown (Y series color was superior to R series color after dyeing). Therefore, it is recommended for cotton to implement T-J method and for silk to implement J-T method in order to enhance both dyeing uptake and emphasize the color of R series. The K/S value of combination dyed fabrics was decreased by increasing washing time; however, the K/S value of combination dyed fabrics was increased by increasing UV irradiation time. But after repeated washing and longer UV irradiation, ${\Delta}E$ value of combination dyed fabric became smaller compared to fabric dyed with Juniperus chinensis only. Thus, it was found that after J, T combination dyeing, fabric became less prone to fading by washing and UV than after Juniperus chinensis single dyeing was done.

  • 한국산 붓꽃속 16종과 1종의 외군을 대상으로 유연관계 및 분류학적 실체를 파악하기 위하여 분자계통학적 연구를 수행하였다. 연구결과, 한국산 붓꽃속은 5개의 Clade로 나타났으며, Clade I에는 Series Laevigatae, Tripetalae, Laevigatae, Sibiricae, Clade II에는 Series Ruthenicae, Easatae, Clade III에는 Series Chinensis, Clade IV에는 Series Chinensis, Clade V에는 Series Crossiris, Pumilae, Pardanthopsis로 나타났다. 대청부채, 만주붓꽃, 연미붓꽃은 하나의 단계통을 형성하여 가장 기저부에 위치하였고, 금붓꽃과 노랑붓꽃은 독립적인 분계조를 형성하지 못하여 두 종의 관계가 명확하지 않았다. 연미붓꽃은 Crossiris속의 Crossiris절로 분류체계를 설정하였다. Chinensis계열은 금붓꽃계열(노랑무늬붓꽃, 금붓꽃, 노랑붓꽃)과 각시붓꽃계열(넓은잎각시붓꽃, 각시붓꽃)로 뚜렷히 구분되었다. 붓꽃속은 크게 4아속(Limniris, Crossiris, Iris, Pardanthopsis)으로 나눠지며, Pardanthopsis아속, Iris아속 그리고 Crossiris아속에서 Limniris아속으로 분화되는 경향성을 나타내었다.

  • 붓꽃속(Genus Iris)의 금붓꽃계열(Series Chinensis)은 극동아시아에 국한되어 분포하고 있으며 한국에는 총 6분류군이 자생하고 있다. 이는 크게 두 개의 주요 그룹 (각시붓꽃 complex와 금붓꽃 complex)으로 나뉜다. 본 연구에서는 팔공산에서 발견된 잡종추정개체들의 실체와 붓꽃속 금붓꽃계열 분류군간의 계통학적 유연관계를 규명하기 위해 핵 rDNA ITS와 엽록체 matK 유전자의 염기서열을 확보하여 분석하였다. 총 55개체로부터 얻은 106 개 ITS amplicon의 염기서열 및 군외군의 염기서열을 분석한 결과, 금붓꽃계열의 노랑무늬붓꽃, 노랑붓꽃, 금붓꽃 및 잡종추정군은 군외군과 구분되어 유집되었으나, 군내군 사이에서는 높은 다형성 염기서열이 관측되었다. ITS 계통수에서 잡종추정군의 일부는 노랑무늬붓꽃과 하나의 분계조를 나타내었고, 나머지 잡종추정군의 경우는 금붓꽃+노랑붓꽃과 분계조를 형성하였다. 한편 cpDNA의 경우 matK를 제외한 나머지 마커는 금붓꽃과 노랑붓꽃의 차이를 보여주지 못하였다. matK의 NJ 계통수에서 잡종추정군이 금붓꽃과 높은 Bootstrap 값으로 하나의 분계조를 형성하였으며, 염기서열이 일치하였다. 이 결과를 바탕으로 팔공산에서 발견된 잡종추정군의 모계는 금붓꽃이고 부계는 노랑무늬붓꽃이라는 가능성을 제시하였다.

  • The purpose of this study was to examine improvements in dye uptake, expression of various colors, and color fastness when washed or exposed to light. We examined these improvements by doing the combination dyeing of Juniperus chinensis heartwood and Alnus japonica heartwood extracts. In this study, two combination dyeing methods were used. One-bath dyeing involves combining Juniperus chinensis heartwood extract and Alnus japonica heartwood extract. Two-bath dyeing involves dyeing by sequence, which means that we dyed the Juniperus chinensis heartwood extract first and then dyed Alnus japonica heartwood extract sequentially (or in the opposite order). In terms of improving dye uptake, two-bath dyeing was more effective than one-bath dyeing. For cotton, dyeing Juniperus chinensis heartwood extract first and then dyeing Alnus japonica heartwood extract sequentially showed higher dye uptake in the two-bath method, while for silk, there wasn't much difference in the dyeing order. Through combination dyeing, red-violet color from Juniperus chinensis heartwood and brown color from Alnus japonica heartwood made various Y, YR, R series of color as a result. Moreover, combination dyeing improved fabric's fastness when washed or exposed to light. In the case of cotton, fabric dyed using two-bath dyeing, with Juniperus chinensis heartwood extract being the first dye, showed improvement in fastness to washing and light. And in the case of silk, fastness to washing and light improved regardless of dyeing order in two-bath dyeing.

  • The purpose of this study was to investigate the characteristics of the pigment and the dyeability of juniperus chinensis needles, berry, bark and heartwood extracts using distilled water, methanol, normal butanol and ethyl acetate as a solvent. Ultraviolet-visible absorption spectrum bands of the extracts were measured at around 280nm to 320nm in all the solvent extracts. The maximum absorption wavelength was able to determine tannin. All the solvent extracts except for distilled water extracts were able to confirm the presence of chlorophyll. Infrared absorption spectra (FT-IR) of all parts of the extracts showed broad absorption bands of OH due to phenolic-OH, benzene CH peak of phenol chemical structure, ether-based stretching vibration peak and the peak of flavonoid compounds that appeared in all the solvent extracts. The yield of juniper needles and heartwood in distilled water and methanol extraction were effective. Extraction of berry yields in distilled water was also effective. The yield of ethanol extraction from the bark showed better efficiency. As a result of using distilled water for the dye solution, the color of the fabrics dyed with all extracts of the needles and Y series berries generally showed light Y progression with a strong red tinge. By using a mixture of 20% ethanol and 80% distilled water for the dye solution, the color of the fabrics dyed with needles and berry extracts showed Y series dominantly. The color of the fabrics dyed with Bark and heartwood extracts were dominantly R series.

  • The purpose of this study is to investigate dyeing properties and functionality of cotton and silk fabrics dyed with hot-water extract from Juniperus chinensis heartwood. Water-soluble dye of Juniperus chinensis heartwood extracted with distilled water was expressed YR color series. Dye uptake of cotton continued to increase according to the increase of the dye concentration. Its variation trends were shown to be similar to the isothermal absorption curve of the Freundlich. Dye uptake of silk was better than cotton, increased depending on increasing concentration of the dye, dyeing time and temperature. Its variation trends were shown to be similar to the isothermal absorption curve of the Langmuir. As the pH increased, the dye uptake of fabrics reduced and showed increased on red tinge. Colors of the dyed fabrics were various, depending on dye concentration and the mordant type and mordant concentration. Washing fastness, light fastness and perspiration fastness were not good. However, rubbing and dry cleaning fastness showed relatively good grade. Dyed fabrics of ultraviolet-cut ability and deodorant ability were improved. And dyed fabrics showed antimicrobial abilities of 99.9% against Staphylococcus aureus.

  • 한국산 붓꽃속(Iris L.; Iridaceae) 15종과 비교군인 등심붓꽃속(Sisyrinchium auguistifolium Mill.)과 범부채속(Belamcanda chinensis (L). DC.)을 포함한 17분류군을 대상으로 RAPD분석이 수행되었다. 10개의 oligoprimer를 이용한 효소중합반응에서 80개의 유효한 polymorphic band가 확인되었다. 유전적 상사도 지수에 의하여 bootstrap을 포함한 neighbour-joining 방법을 통하여 계통수를 평가하였다. 한국산 붓꽃속은 3아속(Limniris, Crossiris, Pardanthopsis) 또는 2속과 1아속으로 분류되어지고, 붓꽃아속(Limniris)은 6개의 분계조를 형성하고 있어 Waddick(1992)이 설정한 2절, 6계열의 분류체계가 더 타당하다고 생각된다. Chinensis계열은 금붓꽃계열과 각시붓꽃계열로 구분되어진다. Tripetalae계열에 속하는 부채붓꽃은 Sibiricae계열(시베리아붓꽃, 붓꽃)과 매우 가까운 유연관계를 형성하고 있으며, Ensatae계열에 속하는 타래붓꽃은 Ruthenicae계열에 속하는 솔붓꽃, 난장이붓꽃과 가까운 유연관계를 나타내고 있다. RAPD 분석자료를 기초로 한 한국산 붓꽃속의 계통학적 연구는 형태학적, ITS 염기서열 결과와 비슷한 결과를 제시하였고, 많은 학자들에 의해 논란이 된 분류군들의 문제를 해결하는데 유용한 접근방법이라 생각되며, 전체 붓꽃속 수준에서의 계통분석에 유용한 도구로 이용될 수 있는 것으로 사료된다.

  • The genetic diversity among the genus Viola was evaluated using the random amplified polymorphic DNA (RAPD) method. A total of 142 distinct amplification fragments by 18 random primers were scored to perform the cluster analysis with UPGMA. Viola species from the subsection Patellares were clustered into group I to IV. The groups from I to IV were consistent with its morphological taxonomy, series Pinnatae, Chinensis, Variegatae, and Patellares in the subsection Patellares, respectively. Even though V. albida and V. albida var. takahasii were classified in Chinensis, they were assigned into group I. The cluster analysis separated other subsections from Patellares in the section Nomimium. Interestingly, V. verecunda and V. grypoceras in subsections Biobatae and Trigonocarpae, respectively, were clustered into group C with a high similarity coefficient. Therefore, RAPD analysis can be used for providing an alternative classification system to identify genotypes and morphological characters of Viola species.
