  • We developed a giant colony test system with rapidly growing mycobacteria by stab-culture with a loopful inoculum of cells into Middlebrook 7H10 agar medium containing soluble extracts of the fruits of Gardenia jasminoides(7H10-crocin agar medium) and assessed the significance of the giant colony test with 28 strains of 10 clusters of rapidly growing mycobacteria classified by the simple biological 5-test characters. Of the 10 clusters of mycobacteria tested, some of strains which belonged to cluster No. 1a, 5a and 11a did grow as gravis types, whereas most of other clusters gave mitis or intermedius types in their colonial sizes at 12 days culture. By this test, pathogenic strains of M. fortuitum-chelonei complex which belonged to cluster No. 5a, b, 7a and 8a, b could be divided into gravis, intermedius and mitis colony types and the gravis ones were characterized by bluish-white "mushroom-shaped" colonies with central complexes in the texture, whereas the intermedius gave grayish-white "flower-shaped" colonies with radiated folds, but without any central complexes. The mitis colonies were characterized by grayish-white smooth or smooth mucoid colonies and were common among the clusters in their shapes. The colony of M. chelonei was bluish-white mitis type and was characterized by its hilly rhizoid colony. The gravis colony of cluster No. 1a identified as M. phlei was characterized by yellow "round straw- mat-shaped" or "chrysanthemum-shaped" colony with whole complexes in the texture, and the gravis colonies of the cluster No. 11a gave grayish-white "flower-shaped" colonies with central stamens, radiating trough and fine cup-shaped strands in the texture. The four colony types of pathogenic species of M. fortuitum-chelonei complex on 7H10-crocin agar medium were distinctive from those of other clusters of rapidly growing mycobacteria and these results indicated that the giant colony test, in conjunction with the simple 5-test characters, would be of value in the differentiation of M. fortuitum complex from other clusters of rapidly growing mycobacteria.

  • This study was carried out to investigate the life cycle of Cephonodes hylas (Linne), that is damaging to Gardenia jasminoides Ellis in the seedbed at Namhae during 1984 and 1985. Results are summarized as follows. The eggs were laid in mass on the leaf surface of the host plants. The oviposition period lasts for 26 days after late-May. The average number of eggs and average hatching rate were 20.36 and 97.61% , respectively. It takes 14-16 days until hatching. The egg shape was oval which its size was 1.01 mm in diameter and 1.48 mm in length. The body length of each larval instar from the 1st to the 5th were $3.52\pm$1.01, $6.46\pm$0.45, $13.19\pm$4.27, $24.08\pm$2.22 and $43.71\pm$5.62 mm, respectively. The average weight of each larval instar were $13.34\pm$2.41, $29.83\pm$6.88, $76.64\pm$31.31, $292.09\pm$107.70 and 2,$144.84\pm$760.70 mm, respectively. The larval period was observed from July to October, and total duration of larval stage was 116 days in which duration of each larval instar from the 1st to the 5th were 12, 36, 32, 16 and 20 days, respectively. During larval stage, a larvae feed on 17~18 seedlings. The 5th instar larvae built its place in soil for overwinter and became pupa. The body length of pupa was 33.6 mm and average weight was 2,032 mg Adult was emerged from overwintened pupa from mid through late-May in the followings year.

  • The color yellow was considered from ancient time to the Chosun Dynasty as the central color. Thus, this color became the royal color for the costumes in the palace. It is generally known to usthat the color yellow was controled in use both for the general public and in the royal palaces. However, in the later part of Chosun Dynasty, the color yellow was used not only for the king's costumes but also used for women's tops and for the linings of clothing. Especially, in some of the costumes that belonged to the later period of the Chosun Dynasty, we can still see lots of bright yellow tops. Also there are many green dyed official robes and various costumes for women. It is a true fact that people could not derive the color green from the plants as they did with yellow. The only way they could make the color green was to mix indigo and yellow together. By repeating the difficult process of making various dyes constantly during many centuries, the Korean people developed the marvelous technique of making natural color. Those plants used to make the color yellow are ; Gardenia, Phellodendron amurense, Turmeric, Coptis, Safflower, Arthraxon hispidus, Styphnolobium japonicum. While synthetic dye causes pollution, natural coloring by plants is as safe and useful as the color itself is lovely. Yet it is tragic to know that this traditional culture of making beautiful natural colors was cut off. There is no way to know today the traditionally correct method to derive colors from the plants. Therefore, it is our aim and challenge to find out the original way to dye and develop it and preserve it as our non-polluted folk art. In regard to natural dyeing, we must say that is very difficult to prepare and preserve natural dyes. In the first place, people had to get the right plants at an appropriate time. Then they could not keep those plants too long. Finally, much depended upon the mordant as well as various conditions and dyeing procedures. All those things influenced greatly the quality of color, some times producing a very pretty color and other times a very dull one. It is very appropriate that the natural dye art should be recognized and appreciated anew by Korea since it provides satisfaction to historical and folk artistic demands as well as to those of fashion conscious modern society for high quality consumption items. We propose two stages of development. The first stage is to explore native dye plants and encourage their cultivation. The second stage is to extract from the plants desirable dye which will enhance national culture.

  • This study explored the efficient dyeing method of aged chestnut wood using the natural dyes extracted from Gardenia jasminoides for, grandiflora, Carthamus tinctorius L., Rhus javanica L., Lithospermum erythrorhizon S. et Z., Caesalpinia sappan L. and Castanea crenata S. et Z.. The color variation of the dyed chestnut woods was also quantitatively evaluated. The wood specimens revealed abundant colors through different dyeing conditions such as dyeing temperature, dye pH, soaking time, and brushing frequency. The chroma and stain concentration of colored woods were calculated with $L^*$, $a^*$ and $b^*$ in order to make color tone measurement. Brushing treatment for colored wood was confirmed as a more economical dyeing method than soaking treatment requiring more time when natural dyeing was done. Furthermore, the desirable tone and shade of color was easily obtained by repetitive brushing treatment using low color tone. During natural dyeing, good color expression was made with high temperature and acidic condition of a dyeing liquor.

  • Objective : Frutus gardeniae, seed of Gardenia jasminoides Ellis is one of the crude drugs used for the treatment of inflammatory condition in oriental medicine. Methodes : The present study aimed to examine the analgesic effect and anti-inflammatory effect of Frutus gardeniae extract (FGE) on a rat model of ankle sprain pain, and the relations between FGE-induced effect and endogenous nitric oxide (NO) and inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), and c-Fos protein expression in the spinal cord. As a chronic pain model, ankle sprain pain model was used to test the effect of FCE injection applied to acupuncture point. After the induction of ankle sprain, rats subsequently showed a reduced stepping force of the affected limb for at least the next 4 days. The reduced stepping force of the limb was presumably due to a painful knee. FGE dissolved in normal saline was injected several acupoints. Results : After the treatment, behavioral tests measuring stepping force were periodically conducted during the next 8 hours. FGE produced significant improvement of stepping force of the hindlimb affected by the ankle sprain lasting at least 4 hours. FGE produced the improvement of stepping force of the affected hindlimb in a dose-dependent manner. In addition, FGE injection showed inhibitory effect on the paw edema induced by ankle sprain. Both NO production and iNOS, COX-2 protein expression increased by ankle sprain were suppressed by FGE. FGE on combination with electroacupuncture (EA) produced more powerful and longer lasting improvement of stepping force of the hindlimb affected by the ankle sprain than either FGE or EA did. The present study suggest that FGE produces a potent analgesic effect on the ankle sprain pain model of the rat and that FGE-induced analgesia modulate endogenous NO through the suppression of iNOS/COX-2 protein expression.

  • The purpose of this study is verification of the anti-oxidant effect and anti-inflammatory effect of Eggplant-cheongyeolsodokum composed of 8 herbs (Solanum melongena L., Lonicera japonica Thunb., Glycyrrhiza uralensis Fisch., Ligusticum chuanxiong Hort., Angelica gigas Nakai., Coptis deltoidea C. Y. Cheng et Hsiao., Gardenia jasminoides J. Ellis., Forsythia suspensa Vahl) to confirm the possibilities as useful cosmetic material. We used the modified prescription of 'cheongyeolsodokum' contained in Korean traditional medical book 'Donguibogam' as composition of Eggplant-cheongyeolsodokum and their proportions. Eggplant-cheongyeolsodokum were extracted with hot water, 70% ethanol and then powdered. To confirm anti-oxidant effect, we investigated radical scavenging ability (DPPH, $ABTS^+$, superoxide), superoxide dismutase (SOD)-like activity, total polyphenolic contents. Also to confirm anti-inflammatory effect, we investigated inhibition effect of nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages, and Inhibition effect of the expression of inflammatory-related proteins (iNOS, COX-2) by western blot analysis. As a result, Eggplant-cheongyeolsodokum showed good anti-oxidant and anti-inflammation effects, we suggest that it can be used as an active ingredient for cosmetics.

  • Twenty kinds of medicinal herbs were extracted by water and 95% ethanol and then antimicrobial activity of the extracts was investigated against various kinds of microorganisms. Water extracts of Gardeniae fructus (Gardenia jasminoides), Lycii fructus (Lycium chinense) and Schizandrae fructus (Schizandra chinensis) showed inhibitory effects on the growth of most of the bacteria. In the case of ethanol extracts, the 3 kinds of the samples such as Gardeniae fructus, Schizandrae fructus and Lithospermi radix (Lithospermum erythrorhizon) showed inhibitory effects on the growth of almost all bacteria. In particular, ethanol extract from Phellodendri cortex (Phellodendron amurense) showed the best inhibitory effect on the growth of S. aureus in the concentration of 0.01%. By the way, inhibitory effects of water extracts from these medicinal herbs were not so good on the growth of fungi but those of ethanol extracts were better and ethanol extracts of Phellodendri cortex showed best. Antimicrobial activity was variable according to the used extracting solvent. For example, inhibitory effets of ethanol ext-racts were $2{\sim}100$ times better than those of water extracts. Ethanol extract of Lithospermi radix was the most effective not only bactericidal effects but also sensory evaluation tests for tastes.

  • Gardeniae Fructus (GF) is a fruit of Gardenia jasminoides Ellis (Rubiaceae) which has been used in traditional medicine. It contains not only geniposide but also resveratrol, a kind of stilbene as a natural antioxidant. In this study, we investigated physiological activities of GF extracts by measuring electron donating ability (EDA), nitrite scavenging ability (NSA), super oxide dismutase (SOD)-like activity and inhibitory effect of tyrosinase activity (ITA). As a solvent, it was extracted with water, 50 and 100% ethanol using microwave. At the concentration of 6 mg/mL, EDA was the highest at 50% ethanol extract but the lowest at 100% ethanol extract, $96.43{\pm}0.25%\;and\;77.06{\pm}0.22%$ respectively. NSA showed the strongest activity at 50% ethanol extract like EDA (6 mg/mL: $75.26{\pm}0.28%$). ITAs were below 20% in all samples and their activities reduced according to increasing concentration. Likewise, SOD-like activities decreased with increasing concentration of extracts in all samples. In conclusion, GF extracts showed low SOD-like activities and ITAs but EDAs and NSAs were fairly high; especially EDA of 50% ethanol extract (6 mg/mL) was high as those of 0.1 and 1% L-ascorbic acid. Therefore the results suggest that GF extracts may be useful as potential sources of natural antioxidants.

  • The natural dyes from Gardenia jasminoides, Carthamus tinctorius L., Rhus javanica, Lithospermum erythrorhizon, Caesalpinia sappan L., and Castanea crenata were extracted under different pH in distilled water, As the pH in distilled water went from acid to alkali, the much deeper colors in the same color tone were generated from the individual plant species. Before dyeing, wood species were treated by different mordants including AI, Cu, Cr and Fe for color-fixing between wood and the natural dyes. Each mordant could develop independent color on the surface of the woods. The wood species dyed by the natural dyes created deep-tone colors according to higher pH and temperature of the dyeing solution, leading to deeper penetration of the dyes into the wood tissues. Finally through the computer modelling of natural-dyed wood furniture, it was confirmed that the colored furniture can adequately be compatible with the current interior spaces of diverse colors.
