Study on Extraction of Flavonoids from Dianthus superbus Assisted with Aspergillus niger Fermentation and Its Antioxidant Activity
摘要
Abstract
[Objective] The research aimed to study the different extraction methods of flavonoids from Dianthus superbus and its antioxidant activity.[Method]Aspergillus niger solid fermentation and liquid fermentation were used to assist the extracting of flavonoids from Dianthus superbus,and the content of them were compared with that by the ultrasonic extraction method.Its antioxidant activity of flavonoids from Dianthus superbus was analyzed by measuring the scavenging action of flavonoids on hydroxyl radical and DPPH radical.[Result] The content of flavonoids by Aspergillus niger solid fermentation was higher than that of liquid fermentation,both of them were higher than that of ultrasonic extraction.The extract of flavonoids from Dianthus superbus had good scavenging effect on hydroxyl radical and DPPH radical.The IC50 of scavenging hydroxyl radical and DPPH radical were 0.065 and 0.046 g/L,respectively.[Conclusion]The study provides a new method for the development and utilization of flavonoids from Dianthus superbus.关键词
