Abstract:
Two types of adventitious roots of Astragalus membranaceus from different altitudes (Antu and Changbai Mountian) were taken as materials to study the effect of the low temperature and low temperature plus light on accumulation of total flavonoids.The results showed that the total flavonoids of adventitious roots of A.membranaceus from Antu increased under low temperature which need light,and reached the maximum at the eighth day(2.37 mg?g-1),which was 1.30-folds compared to the control,and the antioxidant activity increased significantly with the increase of total flavonoids;the total flavonoids of adventitious roots of A.membranaceus from Changbai Mountain was significantly higher than that in Antu,whereas total flavonoids of it were not affected by low temperature and low temperature plus light.It suggested that there were different mechanism of flavonoid biosynthesis in different germplasms of A.membranaceus.
