Abstract:
Taking the adventitious roots of wild Astragalus membranaceus in Changbai Mountain as materials,the biomass of adventitious roots,total flavonoids content and antioxidant activity in vitro at the different stages of growth were measured in this study.The results showed that the growth curve of adventitious roots was “S”type,there were two peak stages for the accumulation of total flavonoids but only one peak for the antioxidant activity.Biomass,total flavonoids content and free radical scavenging rate activity were all the highest when roots grew to 40 days,the values were 0.513 g,2.048 mg/g and 92.29%,respectively.Therefore,40 days were the best harvesting stage for total flavonoids.
