EXTRACTED PREPARATION OF HOVENIA DULCIS THUNB FOR ANTIOXIDATIVE FUNCTION CONTAINING QUERCETIN 3-O-alpha- L-RHAMNOSIDE, KAEMPFEROL 3-O-alpha- L-RHAMNOSIDE, KAEMPFEROL 3,7-O-alpha- L-DIRHAMNOSIDE, CAFFEINE, KAEMPFEROL 3-O-alpha- L-RHAMOSYL(1-6)-O-beta- D-GLUCOSYL(1-2)-O-beta- D-GLUCOSIDE, AND KAEMPFEROL 3-O-alpha- L-RHAMOSIDE-7-O-beta- D-GLUCOSYL-(1-3)-alpha- L-RHAMNOSIDE

摘要

Heotgae trees (Hovenia dulcis Thunb) query from a hot water extract and ethanol extract of the stems and leaves seotin 3- O -α- L- ramno seed, campaign roll 3- O -α- L- people nopi Llano seed, campaign rolls 3,7 - O -α- D L- ramno seed caffeine campaign roll 3- O -α- L- person nosil (1 → 6) - O -β- D- glucosyl (1 → 2) - O -β- D the antioxidant activity of natural substances, such as - [(1 → 3) -α- L- ramno seed β- D- glucosyl -; - glucoside, and campaign roll 3- O -α- L- ramno seed -7- O the presence was detected. That is, freezing a hot water extract obtained by extracting the stem and leaves of the tree heotgae with hot water then dried, the methanol soluble extract obtained is dissolved in methanol through steps such as a variety of column chromatography and HPLC query seotin 3- O -α- L - to separate the seed and ramno campaign roll 3- O -α- L- ramno seed. Further heotgae tree trunk and campaign roll 3,7- O -a- L- di ramno seed caffeine campaign roll the leaves of the ethanol extract from a butanol extract obtained by solvent fractionation 3- O -α- L- person nosil (1 → 6) - O -β- D- glucosyl (1 → 2) - O -β- D- glucoside, and campaign roll 3- O -α- L- ramno seed -7- O - [β- D- glucoside room-a (1 → 3) -α- L- ramno seed] was isolated. Structure determination of the separation material has been made by the MS, NMR analysis, and the separated material was confirmed that have antioxidant activity. Heotgae extract of tree trunks and leaves that contain natural antioxidants provides the use as a functional material having a prophylactic effect of suppressing oxidation and aging.
