목적: 본 연구는 황칠나무(Dendropanax morbifera) 잎에서 메탄올-초음파 추출법으로 유효성분을 추출하여 약물요법을 대체 할 수 있는 기능성 화장품 및 육모제 소재 개발에 자료를 제공하고자 하는 목적으로 수행하였다. 방법: 황칠나무 잎 메탄올-초음파 추출물의 총 폴리페놀 및 플라보노이드 함량을 측정하였고, 항산화능과 아질산염 소거능을 측정하였으며, 항균활성과 최소성장저해농도(minimum inhibitory concentration, MIC)를 측정하였다. HFDPC세포에 대하여 10, 100, 500 μg/mL 농도별로 처리하여 MTT assay를 통하여 세포독성을 평가하였으며, western blotting을 통한 성장인자 발현촉진 및 억제 효과를 측정하였다. 결과: 황칠나무 잎 메탄올-초음파 추출물의 총 폴리페놀 함량은 74.082±7.180 mg/g, 총 플라보노이드 함량은 97.360±2.235 mg/g로 나타났다. DPPH 소거능은 92.440±1.023%로 높은 효과를 보였으며, 아질산염 소거능은 52.6±2.4%를 보였다. Propionibacterium acnes (P. acnes), Pityrosporum ovale (P. ovale), Malassezia furfur (M. furfur) 균주에 대하여 항균활성이 나타났으며, 최소성장저해농도(MIC)는 P. acnes에서는 17.3%, P. ovale는 21.6%, M. furfur 에서는15.7% 농도로 나타났다. 인간모유두세포에 황칠나무 추출물을 10, 100, 500 μg/mL의 처리농도 범위 내에서세포독성은 관찰되지 않았으며, 농도가 증가할수록 세포생육도가 높았다. Western blotting을 통한 성장인자 단백질의 발현및 억제 효과는 대조군 대비 IGF는 156±8%로 발현촉진 효과가, TGFβ2는78.3±10%로 억제효과가 나타났다. 결론: 황칠나무 잎 메탄올-초음파 추출물은 항산화능을 가진 기능성 화장품 및 육모제의 소재로 활용가능성이 있는 것으로 사료된다.
Purpose: This study was conducted to provide data of the material development of functional cosmetics and hair growth products that could replace the drug therapies by extracting the active ingredients from Dendropanax morbifera (D. morbifera) leaf using the methanol-ultrasound extraction method. Methods: Total polyphenol and flavonoid contents of D. morbifera leaf methanol-ultrasound extract were measured. Also, the anti-oxidant capacity, nitrite scavenging ability, anti-microbial activity, and the minimum inhibitory concentration (MIC) were measured. Cytotoxicity of the extract on HFDPCs was examined by MTT assay at concentrations of 10, 100, and 500 μg/mL, respectively. Moreover, the promotive and inhibitory effects of growth factor expression were also confirmed through the western blotting. Results: Total polyphenol and flavonoid contents of D. morbifera leaf methanol-ultrasound extract were 74.082±7.180 mg/g and 97.360±2.235 mg/g, respectively. DPPH scavenging ability was 92.440±1.023%, which was very high, and the nitrite scavenging activity was 52.6±2.4%. Anti-microbial activities were investigated in the strains such as Propionibacterium acnes (P. acnes), Pityrosporum ovale (P. ovale), and Malassezia furfur (M. furfur). The MIC of P. acnes, P. ovale, and M. furfur were 17.3%, 21.6%, and 15.7%, respectively. Cytotoxicity was not observed within the range of concentrations (10, 100, and 500 μg/mL) of D. morbifera leaf methanol-ultrasound extract and the cell growth rate was increased according to the concentrations. In case of the growth factor expression by western blotting, high promotive effect was observed in IGF protein expression (156±8%) compared with the control group, while inhibitory effect was confirmed in TGFβ2 protein expression (78.3±10%). Conclusion: Therefore, it is possible to utilize D. morbifera leaf methanol-ultrasound extract as the material of functional cosmetics and hair growth products with anti-oxidant capacity.
