The Korean Chinese Chives(Allium tuberosum Rottler) are a perennial herb and have been used from ancient as food and medical purpose in Korea. They are known to posses diuresis, sthemia activities and used for the treatment or anemia, haematemesis, and eczema. Recently the Korean Chinese Chives have been studied on the morphologic property, the classification of origin and chemical constituent. However there has not been studied on kg) (or 6 days and observed the hematological effects in dogs. The results are as follows, 1. The red blood cell count was significantly (P < 0.05) decreased on day 2. 2. The reduced glutathion(GSH) concentration was significantly (P< 0.05) increased on day 4 and Met-hemoglobin concentration was significantly (P< 0.05) increased on 3 hrs after administration. 3. Packed cell volume(PCV) and hemoglobin concentration were not showed significant difference during experimental periods. 4. The mean corpuscular volume(MCV) was significantly(P < 0.05) increased on 3 hours after administration.

The purpose of this research was to isolate an active component on immunoytes from 70% MeOH extract of Codonopsis lanceolatae Radix(CLE). CLE was fractionated successively with hexane, methylene chloride, n-butyl alcohol and water, and then the water fraction was separated with molecularporous membrane tubing(m.w. 3,500). Each fraction(50mg/kg) was administered p.o. once a day for 7 days in BALB/c mice respectively. None of these fractions affected the apoptosis and mitochondrial transmembrane potential in thymocyte. Hexane and methylene chloride fractions decreased CD4$^{[-10]}$ CD8$^{+}$ single-positive cells, and the water fraction enhanced CD4$^{+}$ CD8$^{[-10]}$ single-positive cells in thymocyte. The proliferation of thymocytes was decreased by the fraction hexane, but was enhanced by the water fraction. Hexane, methylene chloride and butyl alcohol fractions suppressed the production of nitric oxide, which was not affected by the water fraction. Hexane and butyl alcohol fraction suppressed the phagocytic activity, but water fraction enhanced it. The components(m.w. 3,500 above) separated from the water fraction enhanced the proliferation of thymocyte, the population of CD4$^{+}$ CDB$^{[-10]}$ single-positive cells, and phagocytic activity in macrophage. These results suggest that the stimulative components of proliferation, TH population and phagorytc activity is in the water fraction, and the molecular weight is 3,500 above.

The fruits of Morus alba L. were extracted with 80 % aqueous MeOH, and the concentrated extract was partitioned into EtOAc, n-butyl alcohol, and water fractions. The repeated silica gel ($SiO_2$) and octadecyl silica gel column chromatographies for the EtOAc and n-butyl alcohol fractions led to isolation of two phenolic compounds. The chemical structures of the compounds were determined as Diels-Alder type adducts, mulberrofuran E (1) and chalcomoracin (2) based on spectroscopic data analyses including nuclear magnetic resonance, mass spectrometry, and infrared spectrometry. Compounds 1 and 2 were isolated for the first time from the fruits of M. alba L. in this study.

Sparassis crispa fruits were extracted in 80 % MeOH, and the concentrated extract was partitioned into EtOAc, n-butyl alcohol, and water fractions. The repeated octadecyl $SiO_2$ and silica gel ($SiO_2$) column chromatographies for the EtOAc and nbutyl alcohol fractions led to isolation of two ergosterol peroxides. There chemical structures were determined as ($3{\beta}$,$5{\alpha}$,$8{\alpha}$,22E)-5,8-Epidioxyergosta-6,22-dien-3-ol (ergosterol peroxide) (1) and 3-O-${\beta}$-D-glucopyranosyl ergosterol peroxide (2) based on spectroscopic data analyses including nuclear magnetic resonance, infrared spectrometry, and mass spectrometry (MS). Compounds 1 and 2 were for the first time isolated from S. crispa in this study.

The purpose of this study was to research about the ingredients for anti-oxidation and anti-wrinkle effects of the solvent fractions from Agrimonia pilosa L. hot water (AW) and 70% ethanol (AE) extracts. The electron donating ability of the solvent fractions from AW and AE extracts showed 84.9, 92.5% in ethyl acetate layer of AW and AE at 1,000 ppm. The superoxide dismutase like activity of solvent fractions from AW and AE extracts showed 61.8% in ethyl acetate layer of AW extracts and 58.0% in buthanol layer of AE extracts at 1,000 ppm. For anti-wrinkle effect, elastase inhibition effect of the solvent fractions from AW and AE extracts showed 55.2, 70.1% in ethyl acetate layer of AW and AE extracts at 1,000 ppm. And collagenase inhibition effect of the solvent fractions from AW and AE extracts showed highest inhibition effect as 90.6% in ethyl acetate layer of AW extract and 88.6% in $n$-butyl alcohol layer of AE extract at 1,000 ppm. All these findings suggested that solvent fractions from AW and AE extracts has an anti-oxidation and anti-wrinkle effects.

Chrysanthemum morifolium flowers were extracted with 80 % aqueous MeOH, and the concentrated extract was partitioned into EtOAc, n-butyl alcohol (n-BuOH), and water fractions. The repeated silica gel and octadecyl silica gel column chromatographies for the EtOAc and n-BuOH fractions led to isolation of four flavonoids.

The antimicrobial substances from Rhodiola sachalinensis were extncted, isolated and identified. The highest level of antimicrobial activity and its yield were obtained in methanol extract. The minimum inhibition concentrations of the methanol extract were 500 $\mu\textrm{g}$mL on agar plate and 100 $\mu\textrm{g}$mL in broth media for four gram positive and four gram negative microbials. The methanol extract was fractionated by n-hexane, chloroform, ethyl ether, ethyl acetate, and butanol, orderly. The separate was developed on the TLC plate with different solvent system ratio of chloroform and methanol. Nine substances were isolated from chloroform and methanol mixture(9:1, v/v). Among them, three isolates showed antimicrobial activity. Three substances separated by HPLC were identified by GC/MS(EI) spectrum and $^1$H, /sup13/C-NMR spectrum. They were gallic acid, (-)-epicatechin and kaempferol. The antimicrobial activities of each substances were shown gallic acid, (-)-epicatechin, kaempferol orderly.

The antioxidant potentials of the methanol extract and its various fractions from Agrimonia pilosa Ledeb were measured as 1,1-diphenyl-2-picrylhydrazyl (DPPH), and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging abilities as well as the reducing power decreasing NO in vitro. The methanol extract of Agrimonia pilosa Ledeb showed significantly strong scavenging effects on free radicals of DPPH, ABTS, and NO. Hexane fraction (HF), ethyl acetate fraction (EF) and n-butyl alcohol fraction (BF) were prepared by solvent fractionation. By comparison of polyphenol contents among BF and HF, EF with high polyphenol contents showed the highest DPPH, ABTS, and NO scavenging effects with the value of 50.2%, 80.4%, and 65.7%, respectively, at the highest tested dose. HPLC analysis revealed the presence of various phenolic compounds in EF of Agrimonia pilosa Ledeb. These results suggest that EF could be considered as natural antioxidant sources and dietary nutritional supplements to prevent oxidation-related diseases.

Chipped stem wood from Lindera glauca was extracted repeatedly with 80% aqueous methanol at room temperature, and the concentrated methanolic extract was successively partitioned with ethyl acetate (EtOAc), n-butyl alcohol, and $H_2O$. From the EtOAc fraction, four sterols were isolated through a repeated silica gel and octadecyl silica gel column chromatography. The chemical structures of the sterols were elucidated as ${\beta}$-sitosterol (1), 7-ketositosterol (2), 7${\beta}$-hydroxysitosterol (3), and daucosterol (4). Among them, compounds 2 and 3 were isolated for the first time from the stem woods of this plant.
