Analysis of Active Ingredients as a Cosmetic Material of Glehenia littoralis Extract

초록

Background : This study was carried out to investigate the antioxidative activity and active ingredients of Glehenia littoralis through purification process.
Methods and Results : Above-ground and below-ground parts of Glehenia littoralis, dried in Gangneung, were purchased, crushed, sonicated for 2 hours in 100% ethanol, filtered and concentrated. Above-ground part of G.littoralis which is more effective higher antioxidant effect than below-ground part in 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays. Was used to extract the above-ground part of the solvent fraction according to polarity (hexane, ethyl acetate, water) and HP20 column separation (0, 30, 60, 100% EtOH). Using the fraction was the DPPH assay with high-performance liquid chromatography (HPLC) analysis. Comparing the antioxidant efficacy with that of fraction isolated from Glehenia littoralis extract. Hexane, water layer and 100% EtOH fraction showed lower efficacy than Glehenia littoralis extract. 60% EtOH fraction showed more than 8 times higher efficacy. In order to compare the components according to their efficacy, HPLC analysis was carried out. The fraction (hexane, water layer, 100% EtOH fraction) which showed low antioxidative activity confirmed imperatoin and nonpolar compound, the fraction (ethyl acetate, 60% EtOH fraction) showed a higher antioxidant activity was confirmed 2 flavonoid and scopoletin.
Conclusion : Glehenia littoralis extract showed low antioxidant activity of 893 ㎍/㎖ with IC50 of DPPH assay. However, it showed an increase of antioxidant activity by IC50 of 115㎍ /㎖ of DPPH assay of 60% EtOH fraction by fractionation and separation. Through HPLC analysis, the active ingredient, scopoletin and two flavonoids were identified.
