| titleOfInvention | A kind of extraction process of roxburgh anoectochilus terminal bud flavones and its application in skin-protection product |
| abstract | The present invention relates to a kind of extraction process of roxburgh anoectochilus terminal bud flavones and its applications in skin-protection product, the extraction process includes the following steps: S1: roxburgh anoectochilus terminal bud being successively beaten, is freeze-dried, crushes, extracts to obtain roxburgh anoectochilus terminal bud flavones crude extract to smashed roxburgh anoectochilus terminal bud powder；S2: by the filtering of crude extract obtained by S1, roxburgh anoectochilus terminal bud flavones crude extract is concentrated under reduced pressure to obtain；S3: roxburgh anoectochilus terminal bud flavones crude extract purify up to roxburgh anoectochilus terminal bud chromocor extract using Sephadex LH-20 gel column；Wherein, the process conditions of freeze-drying described in S1 are -70 DEG C~-80 DEG C of cryogenic temperature, cooling time 40h~60h, vacuum pressure 15Pa~25Pa.Extraction process recovery rate with higher provided by the invention, active constituent content in the roxburgh anoectochilus terminal bud chromocor extract extracted is high, impurity is few, has preferable antioxidant activity and inhibits tyrosinase activity. |
