The extracts of selected plants and analyzed phenolic compounds were used to study the effects of alleloKDICicals on seed germination and seedling growth. HPLC analysis of the aqueous extracts of seven species identified 15 phenolic compounds including caffeic acid. Among them, protocatechuic acid was detected at 65.87ppm and 6.84ppm, in Erigeron canadensis and Pinus rigida, respectively. And the extract of P. rigida showed the strongest inhibitory effect on seed germination. The extract of P. rigida leaves significantly inhibited germination and radicle growth of Raphanus sativus var. hortensis for. acanthiformis in direct proportion to concentration. However, germination of Cassia mimosoides var. nomame was stimulated by the treated extracts at the same concentrations, but root growth was inhibited at high concentrations. Except chlorogenic acid, eleven of the twelve phenolic compounds inhibited the germination of R. sativus var. hortensis for. acanthiformis. In the case of C. mimosoides var. nomame, some phenolic compounds such as chlorogenic acid, vanillic acid, protocatechuic acid, ferulic acid, gallic acid and ${\rho}-coumaric$ acid stimulated germination, while the others reduced it.

The purpose of this study is to establish the scientific data of cotton fabric pretreated with skim milk powder and to improve the dyeability. The surface monophology, add on, whiteness, stiffness, air permeability, moisture regain and absorption of cotton fabrics were evaluated by varying concentration of SMP to get the optimal conditions in pretreatment. FT-IR of cotton fabrics pretreated with SMP were measured. Amino acid compositions, viscosity of SMP were evaluated. The K/S values by varying concentration of cinnamon cassia and subtract of dyed SMP-C were measured. I attempted to evalute the color fastness of untreated and AI. The results are as follow; The optimal concentration of SMP was 9%(w/v) to be pretreated with cotton fabrics. From FT-IR spectrum, formation of -NH$_2$ and -COOH was verified by SMP-C. Denaturalization of protein and condensation of carbohydrate, fat, etc. were found in a measurement of amino acid and viscocity. The K/S value of cotton fabrics pretreated with SMP was higher than that of untreated. Most of the color fastnesses were great.

Various cinnamaldehyde derivatives were synthesized and their inhibition activity $(pI_{50})$ of farnesyl protein transferase (FPTase) was measured to examine the structure-activity relationships (SAR) on the basis that FPTase was inhibited by ortho-hydroxycinnamaldehyde derived from extracts of the bark of Cinnamomum cassia Blume. The ortho-substituents on the phenyl backbone of cinnamaldehyde showed higher activity than those with meta- and para-substituents, and the side chain required unsaturated aldehyde. In particular, 2-chlorocinnamaldehyde, 5 showed the highest inhibition activity on the FPTase among them and its inhibition activity $(pI_{50})$ value was 4.45.

Antioxidative effect of ethanolic extracts of various tea materials(Camellia sinensis, Cassia tora, Lyc ium chinense, Polygonatum odoratum, Schizandrae chinensis) on red pepper seed oil was investigated. Ethanolic extracts were added to red pepper seed oil at a concentration of 0.05%(w/v). Two experimental conditions were employed : 50$\pm$0.1oC for 45 days and 150$\pm$3oC for 24 hours. Oxidation of red pepper seed oil was determined by measuring peroxide value and acid value. Electron donating ability(EDA) and total phenolic contents of each extract were also determined. The result showed that the extracts possess an antioxidative activities. The effectiveness of them was in the following order: C. sinensis>C. tora>P. odoratum>S. chinensis >L. chinense. Ethanolic extracts of C. sinensis showed substantially higher EDA value and total phenol contents than other tea materials. These results indicate that the antioxidative effect was strongly related with EDA and total phenol contents.

Mutagenic acivity of essential oils was tested using Salmonella typhimurium TA100 in the presence or absence of 59 fraction prepared from the mouse liver. Growth inhibitory effect of the oils on the bacteria was measured to warrant the mutagenic effect. Most oils were (round to be very strongly toxic against the bacteria at a high dose $(2,000{\mu}g/plate)$. At lower doses than this concentration, the Curcuma longa oil was found to be the most mutagenic with S9 fraction whereas it was not mutagenic without the fraction suggesting that this oil could undergo activation for the mutagenicity by cytochrome P45O. However, the mutagenicity of the Eugenia caryohpylata oil was disappeared under S9 fraction. Other oils obtained from Cinnamomum cassia, Chrysanthemum sibiricum, Paeonia moutan the flower of Artemisia princeps var. Orientalis, Allium sativum, were not mutagenic. This result suggested that antimutagenicity assay on the essential oil is necessary for the biological available substances.
