Several curcuminoids and tetrahydrocurcuminoids (THCs), bearing various hydroxyl and/or methoxy groups on their benzene rings, have been synthesized to study their antioxidant and hydrogen donating capacities using the DPPH method at 25 °C in methanol.The results show that the tetrahydrocurcuminoids are in general much more efficient than their curcuminoid analogs if they include a phenol ...

Background: Antioxidants play an important role to protect damage caused by oxidative stress (OS). Plants having phenolic contents are reported to possess antioxidant properties. The present study was designed to investigate the antioxidant properties and phenolic contents (total phenols, flavonoids, flavonols and proanthrocyanidins) of methanolic extracts from Morus alba (locally named as Tut ...

A comparative study on the antioxidant properties of ...

Density functional theory was employed to investigate the molecular properties of two flavonoids, bractein and cernuoside, that serve as antioxidants. The B3LYP/6-311G** protocol was used for all computations. Investigations were performed in the gas phase and in two solvents with different polarity (water and benzene); the present work was devoted mainly to the determination of the O–H bond ...
