| Popis: | Salvadora persica L. (Sp) has been widely used as folk medicine. This study aimed to identify and assess the significant phenolics' antioxidant activities in young (S1) and old (S2) leaves of Sp. Six flavonoids; isoquercitrin, kaempferol-3-neohesperidoside, myricetin-3-galactoside, apigenin-O-hexoside, isorhamnetin and isorhamnetin-3-neohesperidoside, were identified for the first time in Sp leaves using LC-ESI-QTOF MS/MS analysis. The flavonoid-rich fraction obtained after purification of S1 (S1TF7) has the highest TFC (358.88 ± 0.12 mg rutin equivalent/g) and TPC (180.82 ± 0.82 mg gallic acid equivalent/g) and exhibits significant (p 0.05). The study concludes that S1TF7 can serve as a mean to prevent oxidative diseases, and it merits further pharmacological investigations. |
