- 摘要:
- 以黄芪为试材，采用紫外-可见分光光度法，分析了5个不同采收期的3年生蒙古黄芪的多糖、总皂苷、总黄酮含量，探讨蒙古黄芪的适宜采收期。结果表明：10月上旬采收的黄芪多糖含量最高，达7.79%，8月上旬采收的黄芪黄酮含量、皂苷含量最高，分别为3.18%和0.568%。3年生蒙古黄芪的适宜收获期为9月上旬至10月初，此期间采收的黄芪品质较佳。
- 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.
