In this study we investigated the natural habitats of Allium grayi, Allium monanthum, Allium tuberosum' and Allium schoenoprasmum to develop a fundamental database for their breeding and cultivation. Both Allium grayi and Allium monanthum were growing wild mainly in the areas with the altitude of ${\leq}\;300\;m$. The natural habitats of Allium grayi and Allium monanthum were limited to the altitude of 1,000 and 800 m, respectively. Allium thunbergii was growing at a wide range of altitude from the lowlands (${\geq}\;100\;m$) to the high elevated areas (${\leq}\;1,000\;m$) whereas Allium maximowiczii was growing wild only at the high altitude of ${\geq}\;900\;m$. The number and the size of the natural habitat of Allium grayi were greater than those of Allium monanthum. The natural habitats of Allium grayi were in the Gyeonggi, Gangwon, Jeolla, and Gyeongsang Provinces whereas those of Allium monanthum were found mainly in the Chungcheong and Jeju Provinces. Allium grayi was growing wild in both inland and seaside districts whereas Allium monanthum was mainly in the inland areas.

In this study, the 163 edible plants that are permitted as foods by the Korea Food and Drug Administration, were extracted in methanol. Following extration, their macrophage immunostimulating effects (MIE) were examined using a macrophage from BALB/C mice at four different concentrations of plant extract, such as $10\;{\mu}g/mL$, $100\;{\mu}g/mL$, $500\;{\mu}g/mL$, and $1,000\;{\mu}g/mL$, in vivo. Forty-two samples significantly showed MIEs. Among them, 20 samples had increased MIEs at higher than 10%, as compared to the negative control group. Nineteen samples had increased MIEs at two of the plant extract concentrations, and 3 samples [Allium schoenoprasmum (chive), Aralia elata (fatsia), Capsosiphon fulvescens (seaweed fulvescens)] had increased MIEs at three of the concentration conditions. In particular, Dioscorea batatas (yam) showed MIEs at all concentrations, as well as slightly higher MIEs as compared to the positive control group. Therefore, Dioscorea batatas was evaluated to be an excellent MIE.
