Sixty kinds of medicinal plants were examined upon the cytotoxicity against L1210 mouse leukemia cells. Isolation and purification of effective antitumor substances from Chysanthemum boreale had been performed which appeared strong cytotoxicity, In cytotoxicity test of the each solvent fractions, $ED_{50}$ values of chloroform fraction against L1210, K562 and A549 cells were shown as 3.98, 4.28, 3.84 (${\mu}g/ml$), respectively. Compound I and II were purified from the chloroform fraction. Between the purified compounds, $ED_{50}$ values of Compound I against L1210, K562 and A549 cells were shown as 0.55, 0.0003, 0.001 (${\mu}g/ml$), respectivety. Whereas Compound II was shu as 4.79 against K562.

The purpose of this paper is to investigate the dyeability, antibacterial activity, and deodorization of cotton and silk fabrics dyed with extracted solution from Chrysanthemum boreale. The results are as follows： 1. The optimum conditions of dyeing temperature and time for the cotton fabrics were 90$^{\circ}C$ and 60minutes, while those of the silk fabrics were 60$^{\circ}C$ and 30 minutes respectively. 2. The K/S values of cotton fabrics were slightly higher than those of silk fabrics. The K/S values of both fabrics were slightly increased by mordanting with Cr but were decreased by mordanting with Cu and Fe 3. The colors of the cotton and silk fabrics changed from GY to Y. In both cases, the values of the fabric colors were lowered, and the values of the colors continued to be lowered with Cu and Fe. The chroma and color difference of both fabrics were high and were further increased by mordanting with Cu. 4. The fastness to dry-cleaning and rubbing of the cotton and silk fabrics was very good. The fastness to washing of both fabrics was good except when mordanted with Fe. The fastness to perspiration of both fabrics was fairly good, but the fastness to acid perspiration was poorer than that to the alkaline perspiration. The fastness to light of both fabrics was very poor. 5. The cotton and silk fabrics showed excellent antibacterial activity. Both fabrics mordanted with Cu showed perfect antibacterial activity. 6. The deodorization of the silk fabrics was very good, and that of the silk fabrics mordanted with Cu and Al was excellent, while the deodorization of the cotton fabrics was fairly good.
