Abstract
|
|
|
Objectives : Biological activities of marine resources have been rarely evaluated compared with other herbal medicines. In the present study, we aimed to evaluate antimicrobial activities of aqueous and ethanolic extracts of five marine resources(Porphyra tenera, Laminariae Thallus, Sargassum, Ostreae Concha, Maliotidis Concha) against Propionibacterium acnes.
Methods : Aqueous axtracts of five marine resources were prepared by decocting in tenfold tap water for 3 h. Etanolic extracts were obtained by extracting five marine resources with tenfold ethanol for 72 h at room temperature. The zone of growth inhibition and minimum inhibitory concentration (MIC) were determined against P. acnes after incubation for 48 h under anaerobic condition.
Results : Ethanolic extracts of Porphyra tenera exhibited potent antimicrobial effects(MIC against KCTC3320, MIC against KCTC5527). However, all aqueous extracts tested had no effects on the growth inhibition of P. acnes. In addition, four ethanolic extracts except Porphyra tenera showed little inhibitory effect.
Conclusions : These results indicate that ethanolic extracts of Porphyra tenera has antimicrobial activities against P. acnes and also warrant further development of Porphyra tenera extracts as a natural anti-acne agent.
