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 کاملPhytochemical and Proximate Analyses of Psidium Guajava Leaves
The phytochemical and proximate analyses of Psidium guajava leaves were determined using the methods of association of official analytical chemists (A.O.A.C). The quantitative analyses showed the concentrations (mg/100g) of the phytochemical constituents as flavonoids (0.40 ± 0.02), tannins (0.55 ± 0.01), glycosides (3.76 ± 0.08), alkaloids (0.04 ± 0.00), saponins (3.01 ± 0.01), phenols (0.28 ±...
متن کاملTriterpenoids from Psidium guajava with Biocidal Activity
In continuation of our studies on the phytochemical investigation of medicinal plants available in the foothills of Darjeeling and Teri, we report herein the isolation of two triterpenoids betulinic acid and lupeol from the leaf extract of Psidium guajava and their potential antimicrobial and phytotoxic activities. All the structures of the isolated compounds were confirmed by spectral (IR, NMR...
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...
