|
In this study was investigated the growth effect of Prunella vulgaris. aleutica Fernald( leaf and flower) extracts on various lactic acid bacterias, electron donating ability and hydroxyl radical scavenging activity. The total cell count of Enterococcus faecium KCCM 12118, Lactobacillus rhamnosus KCCM 32826, Lactobacillus plantarum KCCM 11542, Pediococcus pentosaceus KCCM 40464 in the absence at 37oC after 48hr were 2.2×109 cfu/ml, 2.1×109 cfu/ml, 2.3×109 cfu/ml, 2.2×109 cfu/ml. On the other hand, the total cell count of E. faecium KCCM 12118, L. rhamnosus KCCM 32826, L. plantarum KCCM 11542, P. pentosaceus KCCM 40464 in the presence of Prunella vulgaris. aleutica Fernald(leaf and flower) extracts(10%) at 37oC after 48hr were 4.3×109-4.5×109 cfu/ml, 4.3×109-4.5×109 cfu/ml, 4.8×109-4.9×109 cfu/ml, 4.1×109-4.1×109 cfu/ml. The electron donating ability indicated to E. faecium KCCM 12118, L. rhamnosus KCCM 32826, L. plantarum KCCM 11542, P. pentosaceus KCCM 40464 added by 10% Prunella vulgaris. aleutica Fernald(leaf and flower) extracts, respectively. when 10% native plant extracts were added lactic acid bacterias, the electron donating ability is the highest. Hydroxyl radical scavenging activity of L. plantarum KCCM 11542, L. rhamnosus KCCM 32826, E. faecium KCCM 12118, P. pentosaceus KCCM 40464 showed higher than that of control.
