RESUMO
Spearmint essential oil and pure dew were used as research objects, the antioxidant capacity of spearmint was evaluated by measuring the scavenging capacity of superoxide anion radical and hydroxyl radical, providing technical support for the subsequent development and utilization of spearmint truffle and essential oil. The results showed that when the volume fraction (V/V) of spearmint essential oil was 1%, its antioxidant capacity was the strongest, and its scavenging rates of superoxide anion radical and hydroxyl radical were 50.94% and 90.11% respectively; When the volume fraction (V/V) of spearmint hydrosol was 100%, its antioxidant capacity was the strongest, and its scavenging rates of superoxide anion radical and hydroxyl radical were 47.65% and 45.60%.
