Determination of Phenolics and Flavonoid Contents, Antioxidant Capacity and Major Flavonoids Structure in Teucrium perscicum Boiss

摘要

Phytochemical and bioactivity studies of Teucrium persicum Boiss. have been investigated on the aerial parts of the plant. About 2 flavonoids, 5-hydroxy 3, 7, 4-trimethoxyflavone and 5-hydroxy 7, 3′, 4′-trimethoxyflavone were purified and identified from chloroform partition by spectroscopy methods. The crude extracts and isolated compounds were screened for their antioxidant activities using DPPH radical-scavenging, FRAP and Reducing power methods. Methanol extract and isolated flavonoids were found to be the most antioxidant active portions.
