Purpose: The anti-oxidant activity of active ingredients extracted from Rosa multiflora root was evaluated and effects of cell proliferation and growth factor expression were confirmed. Methods: Total polyphenol and flavonoid content of the active ingredients extracted from Rosa multiflora root was measured in various ways, as were 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and nitrite scavenging activity. Further, the cell proliferation effects for human hair follicle dermal papilla cell (HFDPC) were measured using thiazolyl blue tetrazolium bromide (MTT) assay, as were the effects of promoting the expression of growth factors such as platelet derived growth factor subunit B (PDGFB), keratinocyte growth factor (KGF), insulin like growth factor 1 (IGF1), vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), and epidermal growth factor (EGF) by Western blot. Results: The total polyphenol content of six kinds of Rosa multiflora root extracts was the highest in supercritical extracts (101.925 mg/g) and the total flavonoid content was the highest in supercritical extracts (14.365 mg/g). DPPH scavenging activity was the highest in methanol-sonication extracts (98.24%) and nitrite scavenging activity was the highest in supercritical extracts (55.86%). HFDPC was treated with 10, 100, and 500 μg/mL of Rosa multiflora root methanol-sonication extracts to determine cytotoxicity. The cell growth rate increased with increasing concentrations. The effects of the expression of growth factor protein were 135% greater in IGF1 and 126% greater in PDGFB. Conclusion: Rosa multiflora root extracts had no cytotoxicity but had excellent anti-oxidant ability. In addition, because the effects of promoting the expression of IGF1 and PDGFB were significant, it was confirmed that Rosa multiflora root extracts could be used as an antioxidant, functional cosmetic material, and as a natural material for hair restorer and a hair-growth promotion agent.

목적: 찔레나무(Rosa multiflora) 뿌리에서 유효성분을 추출하여 항산화 활성 평가, 세포증식효과 및 성장인자 발현촉진효과를 확인하여 천연성분을 이용한 기능성 화장품 및 육모제 소재로서의 활용 가능성을 탐색하였다. 방법: 찔레나무 뿌리에서 다양한 방법으로 유효성분을 추출하여 총 폴리페놀 및 플라보노이드 함량을 측정하였고, DPPH 라디칼 소거능과 아질산염 소거능을 측정하였다. MTT assay로 인간모유두세포에 대하여 세포 독성 효과를 측정하였으며, 웨스턴블롯을 통해 모발성장인자인 PDGFB, KGF, IGF1, VEGF, HGF, EGF의 발현촉진효과를 측정하였다. 결과: 찔레뿌리 추출물 6종의 총 폴리페놀 함량은 초임계 추출물(101.925 mg/g), 총 플라보노이드 함량은 초임계 추출물(14.365 mg/g)에서 가장 높게 나타났다. DPPH 소거능은 메탄올-초음파 추출물(98.24%)에서, 아질산염 소거능은 초임계 추출물(55.86%)에서 가장 높게 나타났다. 인간모유두세포에 찔레뿌리 메탄올-초음파 추출물을 10, 100, 500 μg/mL의 농도별로 처리하여 세포 독성을 확인한 결과, 처리농도 범위 내에서 세포 독성은 관찰되지 않았으며. 농도가 증가할수록 세포 생육도가 높았다. 웨스턴블롯을 통한 성장인자 단백질의 발현효과는 대조군 대비 IGF1은 135%, PDGFB은126%로 발현촉진효과가 높게 나타났다. 결론: 찔레뿌리 추출물은 독성이 없고 항산화능이 우수하였으며, IGF1과 PDGFB에 대한발현촉진효과가 높게 나타나 항산화제, 기능성화장품, 육모제 및 발모촉진제의 천연소재로서의 활용 가능성을 확인하였다.
