Fruiting bodies of Ganoderma lucidum cultivated in Korea were reflux extracted at $90^{\circ}C$ using water and ethanol under different pH conditions. ${\beta}-Glucan$ contents, extraction yield, and antioxidant capacities of extracts were investigated. Antioxidant activities of water and ethanol extracts were measured by DPPH radical scavenging test and the FRAP method, along with their total phenolic contents and total flavonoid contents. Extraction time for the experiment was determined to be 6 h, and ${\beta}-glucan$ contents were the highest. Overall, ${\beta}-glucan$ contents of extracts increased with higher pH values, except those of 90% ethanol extracts (P<0.05). The yields and ${\beta}-glucan$ contents of ethanol extracts were lower than those of water extracts, and highest in water extract at pH 10 ($8.53{\pm}0.17%$, $6.20{\pm}0.12g/100g$, respectively). Ethanol extracts of fruiting bodies of G. lucidum showed stronger antioxidant capacities than water extracts (P<0.05). Especially, total phenolic contents of 30% ethanol extract at pH 10 was highest (35.06 GAE mg/g). Total phenolic contents of water and ethanol extracts showed good correlations with DPPH radical scavenging activities (r=0.969).

This study was executed to breed new cultivar of E. senticosus suitable for seed harvesting by selection method from 896 native plants collected from 35 regions. Basic selection points were C.V. values of characters such as filament length, blooming period, shoot length, no. of shoot and hundred fruits weight. By four steps of selection, two lines having high biomass yielding, diseases tolerant and fruiting capacities were finally selected and registered as new cultivar of Eleutherococcus senticosus at the Korea seed & variety service by regulation for seed production and marketing of plant variety.
