본 연구에서는 아가위 열매(Crataegi fructus)를 70% 에탄올로 추출하여 추출물의 항산화능과 미백 효과에 대해 알아봄으로써 기능성 미백 화장품의 천연 소재로서의 가능성을 알아보았다. 아가위 열매 에탄올 추출물의 총 폴리페놀 함량은 61.31 mg/g, 플라보노이드 함량은 25.42 mg/g으로 나타났으며, 전자공여능은 $1,000{\mu}g/mL$에서 85.80%, ABTS 라디칼 소거능은 17.3%, 환원력은 0.31로 나타났다. Melanoma 세포에 대한 아가위 열매 에탄올 추출물의 최대 허용농도는 $100{\mu}g/mL$으로 확인되어 세포독성이 미약함을 확인하였다. 멜라닌 생성 저해능은 $50{\mu}g/mL$에서 8.5%, 세포 내 tyrosinase 활성 저해능은 $1,000{\mu}g/mL$에서 46.83 %를 나타내었다. 아가위 열매 추출물은 약재와 식용 및 약용식물로 이용되는 여러 천연물보다 다량의 페놀화합물 및 각종 생리활성 성분을 함유하였으며 항산화 활성 및 미백 효과를 나타내었으며 추후 용매별 분획물을 사용하여 항산화 및 미백 효능을 나타내는 지표성분의 확인의 연구가 진행된다면 연구 결과를 바탕으로 기능성 제품의 첨가제나 천연 항산화 소재 및 기능성 미백 화장품 소재로서 활용 가능하리라 생각된다.

The purpose of this study is to prepare black ginseng and evaluate its antitumor activity. In order to achieve such aim, 5 year fresh ginsenges were steamed at 95'E for 3 hr in pottery apparatus and dried at $60^{\circ}C$ for 12-36 hr. This process was repeated again nine times in same condition. Among the ginseng saponins in black ginseng, the amount of Ginsenoside $Rg_3$ was examined by HPLC. 10.05 mE of Ginsenoside $Rg_3$ was obtained from 1 g of dried black ginseng prepared. The extract of black ginseng exhibited stronger cytotoxic activity against MCF-1, HT-1080 and Hepa 1C1C7 tumor cell lines in vitro than the extract of red ginseng. Also, the extract of black ginseng exhibited stronger antitumor activity(33%) in BDFl mice bearing Lewis lung carcinoma cells(LLC) than the extract of red ginseng(23%). From these results, it was concluded that Black ginseng had antitumor activity suggesting its application for the prevention and treatment of cancer.

Objectives : The main aim of this study was to examine the LC-MS/MS used to identify phenolic compounds of CRE(Coptidis Rhizoma 70% EtOH Extract). Also, we investigated antioxidative activities and Anti-inflammatory activities. Methods : LC-MS/MS Analysis HPLC and LC-MS/MS were performed on a 1260 series HPLC system (Agilent Technologies, Inc., California, USA) and 3200 QTrap tandem mass system (Sciex LLC) operated in positive ion mode (spray voltage set at -4.5 kV). The solvent used was DW and Acetonitrile containing 0.1% formic acid, a gradient system was used at a flow rate of 0.5 mL/min for analysis, and a Prontosil C18 column (length, 250 mm; inner diameter, 4.6 mm; particle size, 5 ㎛; Phenomenex Co., Ltd., California, USA, Biochoff Chromatography) was used. The solvent conditions used in the mobile phases were 0-10 min at 10-15% B, 10-20 min at 20% B, 20-30 min at 25%, 30-40 min at 40%, 40-50 min at 70%, 50-60 min at 95%, and 60-70 min at 95%. The analysis was performed at a wavelength of 284 nm and a temperature of 35℃. The cell viability was measured using a 3-(4,5-dimethyethiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. We examined the effects of CRE on the lipopolysaccharide (LPS)-induced production of nitric oxide (NO) in a RAW 264.7 cells Results : The chemical analysis CRE by Liquid chromatography-tandem mass spectrometry (LC-MS/MS) confirmed that Rosmarinic acid, Ferrulic acid, 3-O-feruloylquinic acid, and 5-O-feruloylquinic acid as phenolic components. DPPH radical scavenging activity was the inhibitory activity of CRE showed at 200 ㎍/mL a statistically significant level. MTT assay demonstrated that the CRE did not have a cytotoxic effect in RAW 264.7 and LPS-induced RAW264.7 cells. Also, CRE reduced NO production in RAW 264.7 cells stimulated with LPS. Conclusions : Based on these findings, The chemical analysis 4 major components CRE such as Rosmarinic acid, Ferrulic acid, 3-O-feruloylquinic acid, and 5-O-feruloylquinic acid. Moreover, we confirmed that CRE has effects antioxidant and anti-inflammatory. The results demonstrate that CRE can be used as an antioxidant and a powerful chemopreventive ingredient against inflammatory diseases.
