  • The effects of ethanol extracts from Astragali membranaceus Bunge (AMB) and A. membranaceus Bunge var mongholicus Hisiao (AMBMH) on antioxidant and nitric oxide (NO) production were evaluated. The total polyphenol contents of AMBMH extracts from two, four, and six-year old roots was 45.3, 71.3, and 78.0 mg/g, respectively. These values and those of total flavonoid content were higher than those of AMB extracts. The DPPH radical scavenging activity was the highest in ethanol extracts from four-year old AMBMH roots. The ABTS radical scavenging activity was also higher than those of AMB in ethanol extracts from four- and six-year old AMBMH roots, but not in two-year old roots. The NO production of ethanol extracts from six-year old AMBMH roots was higher than that of two- and four-year old AMBMH roots. However, there is no significant difference in NO production based on the cultivation period of AMB.
