This study was carried out to identify and quantify the flavonoids from 6 different plant parts of Allium victorialis var. platyphyllum (AVP), including the flower, leaf, root, stem, flower stalk, and flower seed, using liquid chromatography/ mass spectrometry. Two major flavonoids were structurally identified as quercetin (3,5,7,3'4,'-pentahydroxyflavone) and kaempferol (3,5,7,4'-tetrahydroxyflavone) at contents of 11.8-25.8 and $6.0-64.4\;{\mu}g/mL$, respectively. In particular, the flower and root plant parts contained the highest amounts of quercetin and kaempferol compared to the other parts. We also assessed the recovery effects of each plant-part extract of AVP on gap junctional intercellular communication (GJIC) in WB-F344 cells by the scrape-loading and dye transfer (SL/DT) method. According to the results, GJIC was reduced by approximately 70.2% ($62.3{\pm}12.5$ cells) compared to the control ($209{\pm}9.5$ cells, 100%) when 12-O-tetradecanoylphorbol-13-acetate (TPA) was treated alone in the WB-F344 rat liver epithelial cells. However, the stem extract (0.2 mg/mL) restored GJIC to basal levels (92%, $204{\pm}2.3$ cells, p<0.01) and the flower extract (0.2 mg/mL) stimulated GJIC to 82.5% ($172.6{\pm}8.3$ cells, p<0.05), when applied together with the TPA.

The hepatoprotective and nephroprotective effects of Allium victorialis (AV) methanol extracts were investigated on high fat diet (HFD) supplied mice. Treatment of AV extracts (62.5, 125, 250 mg/kg) once a day for 12 weeks markedly decreased the liver steatohepatitis and kidney damages. AV extracts were inhibited the serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN) and creatinine elevations and reduced the histopathological changes of livers induced by HFD supply. In addition, AV extracts strengthened the antioxidative defense system with an increased activity of superoxide dismutase (SOD), glutathione (GSH), catalase and reduced malondialdehyde (MDA) levels. The 125 mg/kg of AV extract showed similar favorable effects as compared with silymarin 100 mg/kg. It is suggested that AV methanol extract administration is beneficial to the improvement of the alleviation of liver and kidney damages in HFD supplement.

The antiobese effects of Allium victorialis (AV) leaf methanol extract were evaluated in a high fat diet (HFD) supplied mice. The changes on the body weight, food consumption, leptin and adiponectin levels as well as the periovarian fat weights and histopathology of adipocytes were examined. The effects were compared with those of a group given 250 mg/kg of metformin. After 91 days of a continuous HFD supply, the mice were significantly showed obesity. However, the obesity induced by the HFD was inhibited by the AV extract treatment at the three different doses (62.5, 125 and 250 mg/kg) respectively. The results suggest that the AV methanol extract is beneficial for improving the diet-induced obesity in humans.

To develop Allium victorialis var. platyphyllum (Liliaceae) for an available functional food, pharmacological experiments on the extracts of this plant were undertaken in the rat treated with streptozotocin, poloxamer-407 and $CCl_4$. The two MeOH extracts were obtained from the leaves and the bulbs, respectively. The three agents, streptozotocin, poloxamer-407 and $CCl_4$, were treated to induce diabetes mellitus, hyperlipidemia and hepatic injury, respectively. Treatment with the leaf extract lowered blood glucose by 24.9% at 200 mg/kg (p.o.) in the STZ-treated rat and prohibited the increase of body weight, water consumption and food intake. This exσact also significantly decreased not only thε plasma cholesterol and triglyceride in the poloxamer-407-treated rat by 35.3% but also serum ALT by 49.0%. The potency was found by overall estimation on the experimental results as followings: 200 mg/kg leaf extract> 200 mg/kg bulb extract> 100 mg/kg leaf exσact> 100 mg/kg bulb extract. These results suggested that this plant might have the availability for a functional food. It was also suggested that the leaves are more effective than the bulbs for the functional vegetable, especially in hyperlipidemia and hepatic injury.

Wild garlic (Allium victorialis var. platyphyllum, AVVP) is a nontimber forest product used as an edible and medicinal vegetable. AVVP is usually propagated form offspring bulbs but it takes a long time to harvest. Using tissue culture technology could overcome this problem. This study investigated the optimal conditions for shoot multiplication, root growth, and plant growth by scooping AVVP bulbs. AVVP bulbs harvested from Ulleung Island, Korea, the main producer of AVVP, were surface-sterilized and used for in vitro propagation. Shoot multiplication was performed by the scooping method. More than five multiple shoots were induced from scooped tissue in Quoirin and Lepoivre (QL) medium containing plant growth regulators (PGRs); the maximum number of multiple shoots were induced from scooped tissue in QL medium containing 0.45 μM thidiazuron (TDZ) after 16 weeks of culture. Roots were induced directly at the base of the shoots in all treatments. In vitro rooting depended on the type of PGRs, and the best root-inducing treatment was QL medium containing 9.84 μM indole-3-butyric acid (IBA). Plants with in vitro roots were transferred to pots containing artificial soil and successfully acclimatized for 4 weeks. The acclimatized plants showed a survival rate of 80% after 20 weeks and gradually promoted growth depending on the acclimatization period. The results of this study will be of great help to AVVP dissemination through sustainable mass propagation.

This study was conducted to gather the basic data on the alpine leek (Allium victorialis) for the expand of consumption and the production of its manufactured goods. Amino acid content in alpine leek leaves and various physiological activities were examined. Seventeen component amino acids and 38 free amino acids from alpine leek leaves were analyzed, and the total contents were 2,693.28 mg/100g for component amino acids and 535.39 mg/100g for free amino acids. Total phenolic compounds in the leaves of alpine leek showed the highest level from the methanol extract (37.7 mg/l), and followed by ethanol extract (31.9 mg/l) and hot water extract (25.4 mg/l). Total flavonoid contents in 1,000 mg/l extract was the highest in the methanol extract (22.2 mg/l). DPPH radical scavenging activity at 1,000 mg/l extract was high in the order of ethanol extract (51.6%), methanol extract (47.3%) and hot water extract (37.2%). nitrite radical scavenging activity Methanol extract from Allium victorialis leaves was the highest nitrite radical scavenging activity (79.5%). Hyperplasia suppression of lung cancer cells (Calu-6) and gastric cancer cells (SNU-601) by the methanol extract from the bulb of alpine leek were 99.9% in the extracting concentration of over 200 mg/l. No significant difference in antimicrobial activity among the 3 different solvents and extract concentrations was observed, and the inhibition zones against the gram-positive and negative microorganisms were ranged from 8.23 to 10.15 mm. It was concluded that physiological activities in a human body could be improved by the intake of alpine leek as a pharmaceutical material, and that it would be useful for the prevention of health risk such as lung and gastric cancers.
