The effect of abscisic acid (ABA) and methyl jasmonate (MeJA) on bulblet formation from the culture of Allium victorialis var. platyphyllum Makino was studied. Shoot clumps were cultured on MS medium containing ABA (0, 0.01∼2.0mg/L) and MeJA (0.01∼5.0mg/L). ABA at low concentrations (0.01mg/L) induced shoot proliferation without bulblet formation. However, bulblet formation started on the medium containing MeJA approximately in 4-6 weeks of culture. Furthermore, 1.0mg/L MeJA resulted in bulblet formation at high frequency (100％) as compare to the control (46.1％). Cortical cells of the bulblets enlarged on medium with MeJA had dense protein-like substance in expanded and round cells when examined under the microscope. The data described here show that formation and enlargement of bulblets from Allium victorialis can be improved by addition of appropriate concentration of MeJA.

In Ulrung floral community the growing environments and nutritive values of wild garlic was investigated. The wild garlic, grown for $3{\sim}4\;years$ in community area, were able to develope bulbs. The bulbs with 2 leaves had the highest ratio of propotion as 75.1% of share among the distribution of bulbs with completely developed leaves and 1 leaf-bulbs and 3 leaves-bulbs had 19.6% and 5.3%, respectively. Also the 2 or 3 leaves-bulbs indicated the better growth states in the part of shoot and bulbs than 1 leaf-bulbs, and there was a significant defferences in each growth between 2 leaves-and 3 leaves-bulbs. On the wild garlics we cannot find out insect injuries. However, there was deseases with symptoms of leaf-spots and lesion from May to June. At first it made a small spots on the leaves, followed by senescence at arrounding area of spots, and then it expanded to whole leaf. This pathogenic bacterium was supposed to be a member of Aristastoma. The contents of crude protein, fat, and carbohydrate in each portion of wild garlics decresed in the order of shoot, expanded leaves and bulbs. On the contrary, crude fibers increased in the same order and so it is not suitable for human consumption nutritional value. However, because the shoots of wild garlics have more than the other Allium sp., the shoots will be a good quality food stuff.

Leaf and bulb of wild garlic (Allium victorials var. platyphyllum) from Ulleung Island and Gangneung region were extracted with water and 70% ethanol and investigated on its antioxidative activity. Total polyphenol content of Ulleung island wild garlic was higher than that of Gangneung region. Total polyphenol content in bulb was high compared to content of the leaves, and 70% ethanol extract of Ulleung Island leaf was high in 72.50 mg/g. Flavonoid content in leaf was higher than that of bulb, 70% ethanol extract of Ulleung Island leaf was high in 73.30 mg/g. Electron donating activity of 70% ethanol extract from Ulleung island and water extracts (55.13%) from Gangneung were higher than those of other extracts. Bulb extracts on electron donating activity were higher than those of the leaf extracts. SOD like activity of extracts was high in 70% ethanol extract of wild gallic leaf cultivated at Gangneung. Hydroxy radical scavenging activity of wild gallic was high in leaf extracts compared to activity of bulb extracts. Hydroxy radical scavenging activity (58.85%) of Ulleung island wild gallic leaf extracts was higher than that of the wild gallic leaves of Gangneung. Lipid peroxidation inhibitory activity was both high in water and 70% ethanol leaf extracts of Ulleung island and Gangneung region, especially, 70% ethanol extract of leaves from Ulleung island was the highest 73.33%. These results suggest that extracts from wild garlic could be used as an antioxidative functional food source.

Analysis of the various constituents and determination of biological activities in the different parts (root, stem, and leaf) of Allium victorialis var. platyphyllum were carried out. Potassium and calcium were detected in higher contents (mg/100 g fresh wt.) than other minerals. The total phenolic content (mg tannic acid eq./100 g dry wt.) decreased in the order of leaves ($792.7{\pm}16.6$) > stems ($160.3{\pm}6.8$) > roots ($101.5{\pm}2.7$), and the total flavonoid content (mg quercetin eq./100 g dry wt.) was as follows: leaves ($497.9{\pm}11.1$), roots ($35.7{\pm}0.4$), stems ($18.5{\pm}1.4$). DPPH radical-scavenging activity and inhibition activity against the formation of cholesteryl ester hydroperoxide in rat blood plasma was higher in the leaves than in roots and stems. Extracts of A. victorialis separated by parts displayed antimicrobial activity against Clostridium perfringens, Staphylococcus aureus, Listeria monocytogenes, Vibrio vulnificus, Vibrio parahaemolyticus, of which the strongest activity was against C. perfringens.

The effects of angiogenesis inhibitor from the extract libraries of Korean and Chinese medicinal plants were investigated using a protein microarray chip. Protein chip was constructed by immobilization of integrin ${\alpha}_5{\beta}_1$ on protein chip base plates and employed far screening active extracts that inhibit the integrin-fibronectin interaction from the extract libraries. The 100 extracts of medicinal plants were obtained from extract bank of National Institute of Crop Science, RDA. The 14 extracts among 100 extract libraries were shown efficient inhibition activity for the interaction between integrin-fibronectin. The medicinal plants of 14 extracts were Vitex negundo var. incisa (Lam.) C.B. Clarke, Epimedium koreanum Nakai, Cedrela sinensis A. Juss, Ipomea aquatica Forsk, Schisandra chinensis Baill, Pulsatilla koreana Nakai, Paeonia lactiflora Pall. var.hortensis Makino, Oenothera odorata, Allium chinense, Allium victorialis var. platyphyllum MAKINO, Polygonatum odoratum Druce var. pluriflorum Ohwi, Hosta lancifolia, Agrimonia pilosa L. var. japonica Nakai and Potentilla chinensis SER. The Paeonia lactiflora, Oenothera, and Agrimonia pilosa from these 14 extracts libraries were shown strong inhibition activity of integrin ${\alpha}_5{\beta}_1$.

This experiment was carried out to find out the dormancy physiology, method of softening culture and evaluation of nutritional value of wild garlic, Ulrung-native Allium victorialis var. platyphyllum. In March, a new bulbs, the shoot and bulbs began to develop until the bulbs showed their complete dormant states in late August. The bulbs renewed to another one in every years. When shoots germinated about $1{\sim}2\;cm$ from mother bulbs, the soft tissues in the mother bublbs was degenerated and finally remained as only fiberous tissues unlike the other bulbaceous plants. There was a high inhibiting activities like ABA in the bulbs. This is believed that this inhibiting substance like ABA in the bulbs is related to the dormancy of wild garlic. Although the immatured bulbs, harvested at May and June, was treated with chilling for 90 days, it didn't germinate their shooting, but the matured bulbs, harvested at July and August, could germinate their shooting over 1 cm in 75 and 60 days chilling treatment, respectively. The shoot elongation was promoted by the longer chilling periods, the later harvesting day and the dark condition. The crude fiber content of leaf and stem increased at more expanded leaf and higher light intensity condition. Since the shoots, grown from germinating to leaf expanding time, had a good quality for food stuff and had less crude fibers, we supposed this period is to be most appropriate for harvesting time.

To search for cytotoxic components from Allium victoriallis , MTT assays on each extract and an isolated component, gitogenin 3-O-lycotetroside, were performed against cancer cell lines. Cytotoxicities of most extract were shown to be comparatively weak, though $IC_50$ values of $CHCl_3$fraction was found to be <31.3-368.4 $\mu\textrm{g}/ml$. From the incubated methanol extract at $36^{\circ}C, eleven kinds of organosulfuric flavours were predictable by CG-MS performance. The most abundant peak was revealed to be 2-vinyl-4H-1,3-dithiin(1) by its mass spectrum. Further, this extract showed significant cytotoxicities toward cancer cell lies. Silica gel column chromatography of the n-butanol fraction led to the isolation of gitogenin 3-O-lycotetroside (3) along with astragalin (4) and kaempferol 3, 4'-di-O-$\beta$-D-glycoside (5). This steroidal saponin exhibited significant cytotoxic activities ($IC_50$, 6.51-36.5 $\mu\textrm{g}/ml$) over several cancer cell lines. When compound 3 was incubated for 24 h with human intestinal bacteria, a major metabolite was produced and then isolated by silica gel column chromatography. By examining parent and prominent ion peak in FAB-MS spectrum of the metabolite, the structure was speculated not to be any of prosapogenins of 3, suggesting that spiroketal ring were labile to the bacterial reaction. These suggest that disulfides produced secondarily are the antitumor principles.

The virgin forests on and around Sungin-bong in Ulreung-do, an island situated between the Korean peninsula and Japanese archipelago, were investigated phytosociologically. They were classified into two communities, i.e. Fagus crenata var. multinervis - Majanthemum dilatatum community and F. crenata var. multinervis - Sasa kuriensis community. The former was subdivided into several units ; Acer takesimense - Allium victorialis var. platyphyllum group, including Tsuga sieboldii - Taxus cuspidata var. tatifolia subgroup and a typical subgroup, and Acer mono var. savatieri - Rumohra standishii group, including Dystaenia takeshimana subgroup and a typical subgroup. The other was subdivided into two subunits ; Acer okamotoanum group and a typical group. It was estimated that this area was orginally covered with beech and maple dominated forest vegetation and with Machilus dominated forest or bamboo forest. However, in these days, The natural vegetation of it has been destroyed and in future, may also be disturbed gradually by human activities. Judging from the coincidence method, the structure and distribution of the forest communities was more related to altitude than to topography. The phytomass, based upon the basal area of each community to $100m^2$ showed that Acer mono var. savatieri - Rumohra standishii group ($BA=7574.1cm^2$, $P=9,882,058cm^3$) haved the largest value and Tsuga sieboldii - Taxus cuspidata var. latifolia subgroup($BA=2126.3cm^2$, $P=1,746,755cm^3$) showed the smallest value. The flora of the vascular plants collected from this area consists of 71 families, 187 genera, 243 species, 1 subspecies, 44 varieties, 6 forms and 294 taxa in total.
