Antioxidant activity of Aegle marmelos and Psidium guajava leaves
Aegle marmelos, Bilwa (AM) and Psidium guajava, Guava, (PG) leaves were screened for phytochemicals by sequential extraction using a series of solvents. The antioxidant components such as β-carotene, α-Tocopherol, glutathione, ascorbic acid, total polyphenols and flavonoids were also analyzed. In addition, the leaves were extracted with methanol (ME), ethanol (EE) and water (WE) and the polyphe...
متن کاملAntioxidant power of phytochemicals from Psidium guajava leaf.
Dried ground leaves of Psidium guajava L. (guava) were extracted by water and aqueous ethyl alcohol 50% (1:10) ratio, and the total phenolic content in the extracts was determined spectrophotometrically according to Folin- Ciocalteu's phenol method and calculated as gallic acid equivalent (GAE). Remarkably high total phenolic content 575.3 +/-15.5 and 511.6+/-6.2 mg of GAE/g of dried weight mat...
