The deodorizing responses of the steam distillate from some medicinal plants(G-3) on three representative malodors were evaluated by estimating the best estimate threshold(BET) of odor responses. With a single spray of G-3, the BETs of malodors such as ammonia, acetic acid, and ethyl acetate were found to increase 4.11, 32.6 and 13.1 fold, respectively, which indicated G-3 possessed a potent deodorizing activity. The deodorizing potency of G-3 was also demonstrated to be as high as and even higher than those of the commercial deodorizing agents.

We report 14 species of flowering plants as new additions to the flora of Laos. These are Illex viridis (Aquifoliaceae), Capparis erycibe (Capparaceae), Euphorbia bokorensis (Euphorbiaceae), Exacum darae (Gentianaceae), Aeschynanthus cambodiensis (Gesneriaceae), Tetraphyllum roseum (Gesneriaceae), Utricularia gibba (Lentibulariaceae), Macrosolen brandisianus (Loranthaceae), Decaschistia siamensis (Malvaceae), Nyssa yunnanensis (Nyssaceae), Adenia penangiana var. penangiana (Passifloraceae), Pentaphylax euryoides (Pentaphylacaceae), Wikstroemia bokorensis (Thymelaeaceae), and Debregeasia wallichiana (Urticaceae). We discovered the species during a botanical survey of the Phou Khao Khouay National Biodiversity Conservation Area (PKKNBCA) of Lao PDR in 2015-2019. In addition, nine rarely collected flowering plant species in Laos are newly reported for the PKKNBCA.

Effect of various fractions from the roots of Patrinia scabiosaefolia (Valerianaceae) and whole plants of Melandryum firmum (Caryophyllaceae) on enzyme activities in mice was investigated. The butanol fractions from both plants caused a significant elevation of serum transaminase activities when administered intraperitoneally, but did not, orally. Prolonged exposure by oral administration of both plants elevated hepatic cytochrome p-450 content, indicating the induction of drug metabolizing enzymes in liver.

To produce several high-quality species of Chwinamul (Aster scaber, A. Tataricus, Ligularia fischeri), leaves of the plants grown in different natural habitats were anlayzed. Contents in vitamin C and $\beta$-carotene were generally higher in plants grown in the field. However, Aster scaber picked form Yongwol and A. tataricus from Mt.Taryong contained relatively higher vitamin c and $\beta$ carotene. Crude protein and fat contents varied depending on the growing area. Ca content was markedly higher in the plants grown in the natural havitats.

Eight species of the genus Angelica in Korea were examined for the activity of affecting drug metabolism and for the presence of coumarins. The results showed that various parts, especially roots and fruits of Angelica plants had strong effects on drug metabolism and that they contained various derivatives of coumarins.

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.
