Abstract:
Taking Radix astragali as test materials，the contents of polysaccharides，saponian and total flavonoids of three-year-old Radix astragali were determined by using UV-Vis spectrum,to discuss the suitable harvest time of Radix astragali.The results showed that the samples of Radix astragali harvested from the beginning of October had the highest contents of polysaccharide，which was 7.79%.The sample harvested from the beginning of August had the highest contents of saponian and total flavonoids，which were 3.18% and 0.568% respectively.The suitable harvesting period of triennial Radix astragali was from the beginning of September to the beginning of October.Radix astragali harvested during this period had the best quality.
