Abstracts

In our study, we investigated the antioxidant effect of methanol extract from the leaves of Picrasma quassioides (PQ) and Chamaecyparis obtuse (S. et Z.) ENDL (CO). Total polyphenol contents of methanol extracts from PQ and CO varied from 138.3 to $367.52{\mu}g/mg$ and total flavonoid contents varied from 8.12 to $46.41{\mu}g/mg$. Contents of polyphenol and flavonoid in PQ were found to be extremely high. In addition, the methanol extract of PQ had a higher antioxidant activity in both DPPH ($4.79{\mu}g/ml$) and ABTS ($7.21{\mu}g/ml$) compared to other plants (CO). Based on the results of the FRAP assay, PQ showed a value of $8.52{\mu}mol/{\mu}g$ and CO exhibited a value of $1.77{\mu}mol/{\mu}g$. The methanol extracts from the leaves of PQ showed the highest radical-scavenging activity in various antioxidant systems.
