Free radical and nitric oxide inhibition of trigona honey

In this study, trigona honey sample was tested to evaluate the free radical scavenging activity and the nitric oxide inhibition activity. The activity was compared with u-tocopherol. The u-tocopherol is a well-known antioxidant substance. The ICso for DPPH free radical scavenging activity and nitric oxide inhibition activity for trigona honey were not determined. The ICso for DPPH free radical scavenging activity and the nitric oxide inhibition activity for n-tocopherol were 47.45 µg ml," and 78. 74 µg ml," respectively. These results indicate that Trigona honey does not exhibit potent free radical scavenging and nitric oxide inhibition activity in contrast to u-tocopherol.
