This experimental study reported the physical characteristics and antibacterial efficiencies of the leaf extractobtained from Artemisia princeps var. orientalis from Kipmo, Gyunggi-do province (Korea). The leaf weightduring drying process were experimentally examined. The weight ratio was 23% after 1 day, compared toinitial weight. After 6 day, the weight of dried sample was almost constant of 12.5%. The extraction yields of thesamples were compared to ethaonl concentrations. The results showed that the yield 2.19% of 50% ethaonlwas much higher than those of other concentrations. Color of the ethaonl extracts were also evaluated byL*a*b* values. As increasing of ethaonl concentration, the L* and b* of the sample solution increased and thevalue of a* decreased. Leaf color changes that occur before and after extraction was also compared. The resultshowed that the extraction resulted in significantly improved yellowness (increased b*) according to ethaonlconcentration. The antibacterial efficiencies of the leaf 50% ethaonl extract obtained from Artemisia princepsvar. orientalis was performed to investigated compared to coumarin derivatives. Esculin, one of the glycosidiccompound of esculetin in Artemisia princeps var. orientalis was contributed to the role of anti-microbial effect. We investigated the inhibitory effects of Artemisia princeps var. orientalis ethaonl extract, esculin and esculetinon E. coli , S. aures and P. acnes using paper diffusion method. The results showed that the ethaonl extractdid not show the inhibition zone. However, esculin showed the antibacterial activities for above three bacterialspecies. Diameter of zone of inhibition shoed 2 mm, 5 mm, and 4 mm, respectively. These results demonstratedthat esculin from Artemisia princeps var. orientalis could be useful as functional ingredient for acne cosmetics.
