Cistanche deserticola from Alashan origin in Inner Mongolia were selected and analysed for their nutritional composition and antioxidant activity.The results showed that the protein content of Cistanche deserticola was 13.08 g/100 g,the fat content was 0.20 g/100 g,the total polyphenol content was(19.90±3.74)mg GAE/g DW,and the total flavonoid content was(10.67±2.56)mg RE/g DW.Both aqueous and ethanolic extracts of Cistanche deserticola were able to scavenge DPPH and ABTS free radicals,showing a dose-effect relationship in the concentration range,and the ethanolic extract of Cistanche deserticola had better free radical scavenging activity.This experiment can provide theoretical support for the development of antioxidant products of Cistanche deserticola.
