The main purpose of this paper is to look into the relationship between pavilion and exhibit in Rodin Gallery. Rodin Gallery is intended to accommodate The Gates of Hell and The Burghers of Calais, two materpieces by the French sculptor Auguste Rodin. In order to retain Rodin's intent, the museum designed by KPF is constructed primarily of glass, which maximizes natural light and minimizes shadows. Thematically, the Glass Pavilion was designed to provide a place of relaxation in a highly urban environment.

Four flavonoids were isolated from the whole plant of Kyllinga brevifolia var. leiolepsis. Their structures were identified as quercetin, (-)-epiafzelechin, vitexin and orientin on the basis of spectral data. This is the first report of the identification of quercetin, (-)-epiafzelechin and orientin from Kyllinga genus.

$\alpha$-Linolenic acid ethylester, $C_{19}$ spiroketalenolether polyyne, herniarin and steroid were isolated from the leaves of Artemisia selengensis (Compositae). The structures of the compounds were elucidated on the basis of spectroscopic evidence. Liver protective effects of these constituents were studied using galactosamine and CCI$_{4}$-induced cytotoxicity in primary cultured rat hepatocytes.

Activity-guided fractionation and repeated column chromatography afforded two cytotoxic compounds R-3 and R-4 from the root of Rumex japonicus HOUTT. Compou nds were identified as musizin and emodin, respectively, by the physicochemical and spectral data. Besides R-3 and R-4, two compounds R-1 and R-2, chrysophanol and physcion, respectively, were also isolated. The compound R-3 and R-4 exhibited cytotoxicity against cultured human tumor cell lines, A-549, SK-OV-3, SK-MEL-2, XF498 and HCT15 with $ED_{50}$ values ranging from 2.68 to $10.06{\mu}g/ml$.

Four antioxidative flavonoids were isolated from the aerial parts of Hypericum erectum. Their structures were identified as quercitrin (I), isoquercitrin (Ⅱ), hyperoside (Ⅲ) and orientin (IV) on the basis of spectroscopic means. Antioxidative activities for flavonoids $I{\sim}IV$ were determined by measuring lipid peroxide using 2-thiobarbituric acid (TBA) method and by evaluation the radical scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. Compound IV, orientin, was found to have strong antioxidative potency.

마늘의 alliinase를 ammonium sulfate 분획과 hydroxylapatite chromatography, concanavalin A-Sepharose affinity chromatography에 의해 정제하여, 23% 의 회수율과 7.6배 정제도를 나타내었다(specific activity 116.6 units/mg). SDS-polyacrylamide gel electrophoresis에서 단일 band를 나타내므로 순수한 aliinase 로 추측되며 이 효소의 분자량은 42K 로 추정된다. 기질로서 S-ethyl-L-cysteine sulfoxide를 사용한 이 효소의 $V_max$값은 2.27${\mu}$monl/mg.min이고 $K_m$은 1O mM이다 . 정제효소의 optimum pH는 6.5 phosphate buffer이며, 40$^{\circ}C$에서 최대활성을 나타내었다. Activation energy value($E^*$)는 4.6Kcal/mole로 추정된다.

Four steroids and one flavonol glycoside were isolated from the ethanol extract of the whole plant of Aconitum pseudolaeve var. erectum. Their structures were identified as ${\beta}-sitost-4-en-3-one$, 22-dihydro-stigmast-4-en-3,6-dione, ${\beta}-sitosterol$, ${\beta}-sitosterol-3-O-{\beta}-D-glucopyranoside$ and $kaempferol-3-O-{\beta}-D-glucopyranoside(astragalin)$ on the basis of spectral data.
