This paper surveys the mordanting and dyeing properties of Rubia akane Nakai appropriate extraction, dyeing and mordanting conditions of Rubia akane Nakai were determined, and the effect of mordanting method on dye uptake and color fastness of the dyed fabric was investigated. The optimum temperature to extract Rubia akane Nakai was during 1 hour in 8$0^{\circ}C$. The effective dyeing temperature and time of silk were 8$0^{\circ}C$, 1hour. The silk fabrics dyed with purpurin appeared red color, with alizarine appeared yellow-brown and with Rubia akane Nakai appeared yellow orange. K/S value of the dyeing fabrics was increased by pre-mordanting treatment. Mordant as Sn and Fe was better than anything else in K/S value. Mordanting treatment method affected color change of the dyed silk. In the case of Rubia akane Ntkai light fastness was increased by Fe and Al mordant treatment, Perspiration fastness of Rubia akane Nakai appeared more than 3 grades geneally. Fastness of abrasion and dry-cleaning appeared mon than 4～5 grades and these fastness improvement were generally effective for post-mordanting treatment.

약리실험 결과 강심작용, 지혈촉진작용, 항균작용, 항암작용 등이 밝혀진바 있는 천초근을 이용하여 항균성 및 천연 식품보존제로서의 이용가능성을 검색하여 보았다. 먼저 천초근의 뿌리성분을 petroleum ether, chloroform, ethylaetate, methanol 및 증류수를 이용하여 항균성분을 추출하여 9종의 식중독균(Staphylococcus aureus, Bacillus cereus, Salmonella Enteritidis, Shigella flexner, Escherichia coil, Salmonella Typhi, Shigella dysenteriae, Pseudomonas aeruginosa, Shigella sonnei)에 추출물의 농도를 250ppm, 500 ppm, 1,000ppm으로 달리하여 disc method로 실험한 결과 Salmonella Typhimurium애서 아주 약한 clear zone이 형성되긴 하였으나 거의 모든 균에서 항균작용이 있는 것으로 나타났다. 가장 큰 clear zone이 형성된 균은 Pseudomonas aeruginosa였고 추출물의 농도가 높아질수록 비례하여 항균효과가 크게 드러났다. 또 methanol 추출물에서 항균활성이 가장 잘 나타났으며 그 다음으로는 ethylacetate, chloroform, petroleum ether, 증류수 순이었다. 항균활성이 가장 잘 나타난 천초근의 methanol 추출물과 또 다른 겨우살이 추출물을 사용한 상승효과 여부를 알아보기 위한 실험결과 그람 양성균인 Bacillus cereus와 그람 음성균인 Pseudomonas aeruginosa에 대해 상승적인 항균효과를 나타내었다. 천초근의 methanol 추출물이 Bacillus cereus와 Pseudomonas aeruginosa균의 성장에 미치는 효과를 검정해 본 바 천초근 추출물의 농도가 진해짐에 따라 균의 증식을 억제하는 것으로 나타났고 Pseudomonas aeruginosa에서 더 두드러지게 증식이 억제되었다. 또 72시간 동안 그 성장 억제 효과가 지속됨을 알 수 있었다.

The tissue culture of Rubia cordifolia var. pratensis and R. akane were performed to enhance the biosynthesis of anthraquinone pigments under various conditions. The production of alizarin and purpurin in the callus was separately analysed and was quantitatively compared. The pigment biosynthesis was more active in the callus from R. cordifolia var. pratensis than from R. akane. The addition of ${\alpha}-ketoglutaric$ acid, a biosynthetic precursor of anthraquinones, enhanced the production of alizarin and purpurin remarkably.

The fashion industry saw the emergence of environment-friendly and natural fabric materials recently. The naturalism trend has established sectors in the textile and fashion industry also. Ramie and hemp have long been favored fabric materials in Korea especially for summer. The hand-related mechanical/physical properties of the fabric specimens were analyzed using a fabric objective measurement system, KES(Kawabata Evaluation System). Subjective evaluation was also implemented based on a series of selected adjectives. Studies on natural dyeing methods are important since the establishment of scientific approach is needed in terms of environment and human safety along with the reproduction of traditional natural dyeing methods. In this study, linen, ramie, hemp, and cotton/polyester/linen union fabric specimens were used for the natural dyeing using Rubia akane Nakai with the mordant of gallnut. ${\Delta}E$ values of dyed fabric specimens, mordanted and dyed once using Rubia akane Nakai, increased significantly compared to those of repeatedly dyed fabric specimens without mordanting.

A Korean folk medicine, "SinKyungCho" has been used to cure common cold and rheumatis. While this crude drug has similar morphological feature to that of Rubia species, the botanical origin has never been studied pharmacognostically. Therefore, in order to clarify the botanical origin of "SinKyungCho", the morphological and anatomical characteristics of Rubia species growing in Korea, i.e. R. akane, R. chinensis var. glabrescens, R. cordifolia var. pratensis, R. cordifolia var. sylvatica were studied. Especially, differing from the other three species, R. cordifolia var. pratensis has 2-4 cork cell layers under the endodermal cell layer. R. cordifolia var. sylvatica showed the largest number of parenchyma cell layers in cortex by 8-17. While the average ratio of stele to root transverse section is over 45% for R. akane and R. cordifolia var. pratensis, the ratio is under 45% for R. chinensis var. glabrescens and R. cordifolia var. sylvatica. According to these morphological criteria, the folk medicine "SinKyungCho" from Korean traditional market was proved to be the underground part of R. akane.

The crude drug 'CheonKun' is derived from the underground portions of Rubia species. However, the aerial parts of the plants are also sold under the 'GgogDuSeoNiIp' in Korea. To clarify the botanical origin of 'GgogDuSeoNiIp' the morphological and anatomical characteristics of the leaves of Rubia species growing in Korea, i.e. Rubia akane, R. chinensis var. glabrescens, R. cordifolia var. pratensis were compared. As a result, it was determined that 'GgogDuSeoNiIp' was the leaf of Rubia akane and R. cordifolia var. pratensis.

To search for inhibitory activities for lens aldose reductase, twenty two medicinal plants were tested by the method of bovine lens aldose reductase inhibition test. In this test Rubia akane(68%), Artemisia selengensis(61%), Lespedeza cuneata (58%), Ligustrum lucidum(58%), Viola patrinii(58%) extracts were shown to have aldose reductase inhibitory activity. From the radix of Rubia akane, $2-methyl-1,\;3,\;6-trihydroxy-9,\;10-anthraquinone-3-O-(6'-O-acetyl)-{\alpha}-rhamnosyl-(1{\rightarrow}2)-{\beta}-D-glucoside$ was isolated and the $IC_{50}$ of this compound in the aldose reductase inhibition test was about $1.2{\times}10^{-6}M$.

The purpose of this study was to develop high-quality naturally dyed leisurewear with images of traditional Korean clothing that keeps a psychologically comfortable and physically pleasant environment at home and in vacation spots. The root bark of elm trees, the atopic skin, is also known to be effective for the relief of rhinitis and atopic diseases as well as stress and insomnia. However, there is insufficient color in the bark for the dyeing of fashion products, so to compensate for the lack of color, for dyeing purposes it was combined with a composite extract called Rubia akane Nakai resulting in a relatively bright red color. Except for the light fastness, all the fastnesses were rated 4 to 5, showing excellent results. Through complex dyeing using elm bark and pods extract the author produced four high-quality vests, one-piece, a gown, and jeogori-pantsuits of silk materials with Korean images that are suitable wear for relaxing comfortably at home and during breaks and which provide a comfortable and physically pleasant experience. The vest was made with the formal style of Bae-ja and Dang-eu, the dress is made of Cheok-lik, and the gown is made of Wonsam. It will be meaningful at a time when the importance of rest is increasing due to the healing clothes worn by busy modern people.
