여드름 개선용 화장품 소재 개발을 위한 솔잎 발효물에 대한 기능성 연구

Abstract

In this study, the pine needles were fermented with microorganisms originated from
 Jeju island and the antioxidant and antibacterial activities of the fermented extracts were
 investigated to develop new cosmetic materials. The microorganisms used for
 fermentation were Bacillus coagulans KK7 strain, Lactobacillus brevis GJ26 strain, and
 Pediococcus acidilactici BDD10 strain isolated from Jeju. The antioxidant activities of the
 fermented and non-fermented pine needles extracts were evaluated by the DPPH radical
 scavenging activity. The DPPH radical scavenging activities of the fermented pine
 needles extracts were relatively higher than the non-fermented pine needles extracts. In
 order to examine whether the fermented pine needle extracts can be used as acne
 improvement materials, antibacterial tests were conducted on Cutibacterium acnes,
 Staphylococcus epidermidis and S. aureus. The antibacterial activities of the fermented
 and non-fermented pine needles extracts against C. acnes were confirmed, and the
 extracts of pine needles fermented by BDD10 strain showed better antibacterial activity
 compared to non-fermented pine needles extracts. These results suggest that fermented
 pine needles can be used as a new cosmetic material with antioxidant and antibacterial
 functions.
